I would determine what kind of cell it is by cutting the cell open, then looking around inside the cel to see if it has a cell wall, a cell membrane, etc. If it has a cell membrane, then it is a Eukaryotic cell. A Prokaryotic cell does not. Another way of finding out which kind of cell it is could be to cut it open, then look around if it has cloroplast. If it has cloroplast, then it is a Eukaryotic cell.
Under the microscope, I must look for whether the cell has a cell wall, determining if it is prokaryotic or eukaryotic.
Well for me to find out wether the extraterrestrial matirial has Eukaryoti cell or either Prokaryotic cells I would look at it closely. I would need to look it threw a Microscope to tell wether what cell details it has. I would first look in it. If I cant see if I can cut it open and see what deatils the extraerrestrial matireal has. Now that I know that what the cell has I can determine if the cell is a Eukaryoti cell or Prokaryotic cell. The way I would know if the cells is eather of these two cells is cause I know the details of these two differnt cells. If it is a Prokaryotic cell it would have a Cell wall surroinding the membrane, No nuclues. I would Also know the diffence between the Eukaryoti cell because this cell has No Cell wall but has a Nucleus. But they both have DNA(genetic matireal)and Cytoplasm. These are the details that I would look for into the cell to tell what kind it is or what it's related to.

I will try to proceed to find out if the organisms are eukaryotic or prokaryotic. I will look to see if the organism has a cellwall, or not.If it does it is most likely a prokaryotic cell. If it has a cytoplasm, a nucleus and organneles, it is definetly a eukaryotic cell. A major difference between the 2 is that a eukaryotic cell is complex while a procaryotic cell is simple.
Bacterias have prokaryotic cells but plants and animals have eukaryotic cells
We will first have to have the tools to determine which contain PROKARYOTIC or EUKARYOTIC cells. We know that PROKARYOTIC cells have a cytoplasm, DNA, unicellular, has a cell wall that surrounds the cell membrane and they existed from over 3.5 billion years ago. The EUKARYOTIC cells also have a cytoplasm and DNA but they can be multicellular, not all have a cell wall. This cell has a nucleus unlike the PROKARYOTIC. So this can also help us examine the extraterrestrial material that was found on our spaceship. I think the main tool we would need is a powerful microscope, this will give us all the information we need.

If the smaples contain prokaryotic or eukaryotic cells I will determine them by making sure that the Prokaryotic cell has a nuceloid region, plasma membrane,cytoplasm,DNA and ribosomes. To check for the eukaryotci cell I have to make sure it has a plasma membrane, cytoplasm,DNA,nucleus and ribosomes. Both of these cells have a few similar things they also have their differneces things too. Like in the Prokaryotic it doesn't have a nucleus like the eukaryotic does. The eukaryotic cell doesnt have a nucleoid region and the proaryotic cell does.
To find this out, you need to first examine the living thing. Using a high-tech microscope, examine the cells of this living thing. You would need to see what kind of cell it is, either Prokaryotic or Eukaryotic. The difference between these two kinds of cells is that a Prokaryotic cell contains a Nucloid section when a Eukaryotic cell contains a Nucleus. Both contain a plasma membrane, Cytoplasm, DNA, and Ribosomes. That is how you would find out if they contain what kind of cell.

If I were a scientist and living things landed on the spaceship, my goal would be to find out what type of cells it contained, prokaryotic or eukaryotic cells.
The first thing would be to observe the physical features. If there were many of these living things I would perform surgery on 5 of them. I would have to see if the cell is complex or simple by the first glance. Afterwards I would have to investigate to see if it has a nucleus, if the cell has a nucleus it is a Eukaryotic cell. The nucleus is important to know because the two cells have similar characteristic like they both contain DNA in them, but only the eukaryotic cell contain a nucleus. It would be a short easy experiment.
To find out if the extraterrestrial material containing living things is prokaryotic or eukaryotic first I will measure the cells. Prokaryotic cells are usually .1 - 10 mini meters while Eukaryotic cells are 10 - 100 mini meters. Another way I would determine what kind of cell it is I would check to see if it is multi-cellular or uni-cellular. If it is multi-cellular that means it can only be eukaryotic but if it is uni-cellular it can be either prokaryotic or eukaryotic. If i still can not determine what kind of cells the extraterrestrial has I would check where the nucleus is because in prokaryotic cells the nucleus is more spread out and not usually in the same place while the eukaryotic cell's nucleus is usually in the same place.
If I were a scientist in NASA, I would differentiate Prokaryotic and Eukaryotic cells by checking if they have a nucleus and if they do, that is a Eukaryotic cell. If they have a cell wall surrounding the membrane, it is a Prokaryotic cell.

If I was a scientist with NASA and found extraterrestrial material containing living things, I would need to find out if the samples have prokaryotic or eukaryotic cells. I would follow this step by seeing if one has a nucleus or a nucleoid region. If it has a nucleus it would then have eukaryotic cells. If it has a nucleoid region, it would then be a prokaryotic cell. If the material has types of bacteria it would be prokaryotic cells. I wouldn't be able to tell if the extraterrestrial material has prokaryotic or eukaryotic cells when finding a plasma membrane, DNA, a cytoplasm or ribosome’s. I wouldn't be able to see this because prokaryotic and eukaryotic cells both have those things.

I would see if the extraterrestrial was multicelluar or singlecelluar. I would also seeif the cell contain a membrane, cytoplasm, DNA, nucleus, or a tail. These things help us determine whether the organism is Prokaryotic or Eukaryotic cells.
if a sample of extraterrestrial material containing living things have arrived on my spaceship i would determine if it is prokaryotic or Eukaryotic cells. I will proceed to find out which it is by seeing if it has a nucleus or a membrane. if it is prokaryotic it is a single celled organism that does not have a nuclear or membrane bound organnells; include archaebacteria and monera. if it is a eukaryotic cell its organisms made up of cells that have a nucler membrane, many chromosomes, and mitosis' includes protists, animals, plants, and fungi.
To find out if the material has PROKARYOTIC or EUKARYOTIC cells you would have to carefully examine the material. First you would have to break the material apart so you can properly examine it. Then I would have to use a microscope to take a close look.
Then I would gather information based on the appearance of the material through the microscope. With this method you can determine whether the material contains PROKARYOTIC or EUKARYOTIC cells.

I would determine if the samples contained prokaryotic or eukaryotic cells by looking for characteristics distinctive to each respective group. For example, I would use a microscope to look and see if the samples contain a nucleus or not. I would also look to see if they contained organelles and, in the case of eukaryotic cells, if the cells walls were made out of cellulose.

There are different characteristics that can help identify is the samples are prokaryotic or eukaryotic. For example, Prokaryotic cells do not have a nucleus, while eukaryotic cells have a nucleus. Prokaryotic cells gave a nucleoid regoin, while eukaryotic cells do not. Also, they have different shapes. Prokaryotic cells are small with spikes and tails. However, eukaryotic cells are larger and are round. That is how you can tell the difference.
I would determine it is a prokayotic cell because I know it is smaller than a eukaryotic cell and it is simple and a single cell. I would determine it is a Eukaryotic cell if it contained a nucleus, and is more complex than the others. It is also multicellular. I would be able to determine them and notice the difference between them.

The way to tell a Prokaryote cell from a Eukaryote cell is mainly the Eukaryote cell is bigger in size. Prokaryotes are more diverse than Eukaryotes and are also less complex than Eukaryotes. Prokaryotes have evolved to a multitude of metabolic strategies and are found in a wide range of habitats, including conditions where Eukaryote cells fail to survive.

alright, if I was a scientist for nasa and some extraterrestrial things flying around, and if I had to see if they had either prokaryotic or eukaryotic cells I would make a chart to classify them like we did in class today. I would also test the extraterrestrial things if they had similar cells as the eukaryotic and prokaryotic cells and then if they are similar I check for the differences to classify one from another.
If I was a scientist at NASA and Extraterrestrial cells were found on my ship I would try to find whether they were prokaryotic or eukaryotic in steps. First I would attempt to find a sample of the cell, next I would Use a microscope or some other form of lookingat the cell to determine whether it had the characteristics of Prokaryotic or Eukaryotic cells. This Would be the way I would find out what type of cell the foreign "Contaminent" is.
In order for me to determine whether the samples are Prokaryotic or Eukaryotic cells, there would be many things that i would check to see. Prokaryotic and Eukaryotic cells have many things in common. So seeing if the samples contain a plasma membrane, cytoplasm, DNA, and Ribosomes are not enough, for both types of cells contain all of those things. To pick them apart, Eukaryotic cells have a Nucleus. Prokaryotic cells do not have a nucleus, rather they have a nucleoid region. Prokaryotic cells are simple and unicellular, where as Eukaryotic cells are more complex and they can be unicellular, but mostly multicellular. The last thing that mostly makes the difference is if the cell measures from 0.1 to 10 micrometers, then it is a Prokaryotic cell. If it measures 10 to 100 micrometers, then it can be determined as an Eukaryotic cell.

The main differences between the two types of cells is that eukaryotic cells have a nucleus, prokaryotic cells don't. Also, Eukaryotic cells have membrane-bound orgenelles. Eukaryotics are also usually multi cellular, as opposed to prokaryotic cells that are only one cell. Prokaryotic cells actually have two different kinds: archeabacteria and eubacteria. Archeabacteria are known to thrive in extreme places.

If I were a scientist with NASA, and I came across some extraterrestrial material containing living things, I would first look at the cells under a microscope. If the cell had a cytoplasm, DNA, was simple, had a Cell wall, and no nucleus, then the cell would be a prokaryotic cell. If the cell had all of these things, but had a nucleus, then it would be a Eukaryotic cell.
If I were to determine if a living thing was prokaryotic or eukaryotic, the first thing that I would do is see if the cell is simple or complex. Then I would look at the size. If it was small it would be a prokaryotic cell and if it was bigger than a prokaryotic cell, it would be a eukaryotic cell. After that I would see if it was unicellular or multicellular. If it is unicellular it could be either prokaryotic or eukarotic, but if it is multicellular it has to be eukaryoic.

The process that i would use to find out if the samples contain prokaryotic cells or eukaryotic cells is by looking at it and if the cell does not have a nucleus then it's a prokaryotic cell and if it does have a nucleus then it's a eukaryotic cell

While I was working with NASA, some samples of extraterrestrial materials containing living things have arrived on my spaceship. When I first saw the samples of extraterrestrial, I was thinking if the sample contains Prokaryotic cells, or Eukaryotic cells. A Eukaryotic cell is a orgaqnism that is made of cells that have nuclear membrane, may have choromosomes, and mitosis. It includes protists, animals, plants, and fungi. Prokaryotic cells are a single celled organism that does not have a nuclear or membranebound organelles. It includes archaebacteria and monera. I can also determine which cell it is by knowing there similarities and differences. I know that there similarities are that they both have a plasma membrane, Ribosomes, they are unicellular, cytoplasm,and DNA. I also know that the Prokaryotic cell is simple, and it is smaller then the Eukaryotic cell. It has a Nucleoid region. An example of this cell is the kingdom Monera. On the other hand, the Eukaryotic cell has a nucleus, and it is longer than the Prokaryotic cell.This cell can also be multicellular. It is a complex cell. An example of this cell is a plant cell, or an animal cell.
to see which samples contain prophylactic and eukaryotic i will have to compare which has the details of that cells.
IF I WERE SCIENTIST, TO FIND OUT IF SOME SAMPLES OF EXTRATERRESTRIAL MATERIAL CONTAINING LIVING THINGS HAVE ARRIVED ON MY SPACESHIP CONTAIN PROKARYOTIC OR EUKARYOTIC CELLS, I WOULD EXAMINE THESE THINGS WITH MY MICROSCOPE, AND TRY, AND LOOK TO SEE IF I SEE ANY OF THESE CELLS. IF NOT I WOULD ALSO ATEMPT TO COMPARE THE LIVING THINGS BASED ON MY PRIOR KNOWLEDGE OF THESE CELLS. FOR EXAMPLE IF THE LIVING WERE AN ANIMAL AND FUNGUS. THE ANIMAL WOULD BE PROKARYOTIC AND THE FUNGI WOULD BE EUKARYOTIC.
Well i would start by identifing if the cell has a nucleus. if the cell has a nucleus then i know the cell is prokaryotic but if the cell has no nucleus then it is a eukaryoric

I am a scientist with NASA. Samples I have found arrived at my spaceship. It seems to be some extraterrestrial material that contains living things. My first task is to determine if the material found contains either Prokaryotic or Eukaryotic Cells. I am going to first take some of the material and place it underneath a microscope.
When I locate a cell, I will find out if the cell contains a nucleus or not, because that will automatically conclude what kind of cell it is, because Eukaryotic cells contain a nucleus, and Prokaryotic cells do not contain a nucleus. I have to look out for the differences between Prokaryotic and Eukaryotic cells. Prokaryotic Cells have a Nucleoid Region, and Eukaryotic cells do not. I can tell what kind of cell it is by just gaining that simple information.
To determine if the cell(s) from the extraterrestrial material is either Prokaryotic or Eukaryotic, I can also compare those cells to a legitimate cell that is Prokaryotic and another cell that is Eukaryotic. That way, I can also compare the size of the cells from the material, because the Eukaryotic cell is larger than a Prokaryotic cell. I will also be aware of the simplicity of the cell, because Eukaryotic is more complex. If the cells from the material contain characteristics of a Eukaryotic cell, then the material, indeed, contains Eukaryotic cells, same for Prokaryotic cells.
To find out if the samples contain prokaryotic cells I would look for cytoplasm, DNA, unicellular structure, a cell wall surrounding a cell membrane, and no nucleus. To see if it had eukaryotic cells I would look for cytoplasm, DNA, a unicellular or multicellular structure, cell wall or no cell wall, a nucleus and membrane bound organelles.
Some samples of extraterrestrial material containing living things that have came to the spaceship had cells which were prokaryotic and eukaryotic. I will proceed to find which Is prokaryotic by seeing if they lack a membrane bound nucleus. In prokaryotic cells the outer boundary is plasma membrane itself. The prokaryotic cells are going to be unicellular. To find out which cells are eukaryotic cells are more complex than the prokaryotic cells, so it will be easy to determine which is which. Eukaryotic cells contain internal membrane bound structures called organelles. The eukaryotic cell structure carry put the many functions required for the cell to survive, reproduce, thrive, and grow. This is how I would determine if he samples would contain prokaryotic or eukaryotic cells.
d.seizingerclass902
You can determine an extraterrestrial material is eukaryotic by checking if it's cell has a nucleus.You can determine if it is prokaryotic by checking if it's cell has a tail.You also have to check what shape it is.
To see if the samples have prokaryotic cells I´d have to see if it the cell has a membrane, a nucleoid region, and is 0.1-10 mico meters. If the samples were made up of eukaryotic cells I´d need to see if it has a nucleus, is complex, and is 10- 100 mico meters.
Michelle R.- period 3
if I was a scientist with NASA, and I was trying to determine if the samples contain PROKARYOTIC or EUKARYOTIC cells I would first check and see if the material had a nucleus, if it did then it is a eukaryotic cell. If it only has a nucleiod region then it is a prokaryotic cell. If the cell is samll and simple is another clue that it is prokaryotic cell. If it is big and more complex it is defenitly a eukaryotic cell.
Ashley Disalvo, Period 3
First I need to identify what kind of cell it is. I will do this by first seeing what the cells contain. I know that prokaryotic cells and eukaryotic cells both have the following: plasma membrane, cytoplasm, DNA, and ribosomes. That's what they have in common. To find out which is which I would first see if it's larger than the prokaryotic or smaller than the eukaryotic. I know that prokaryotic cells have a nucleoid region and eukaryotic has a nucleus enclosed. Prokaryotic cells are simple and unicellular and eukaryotic cells are complex and unicellular/multicellular. These are the steps I would take to find out if it's a prokaryotic cell or eukaryotic cell.

To determine if the samples contain PROKARYOTIC or EUKARYOTIC cells I would look at them under some kind of telescope because cells can't be seen by the naked eye. I'd have to look at the functions to see what the cell has and what it doesn't have to tell the difference, and know what a prokarytic cell contains and what an Eukaryotic cell contains. The cells that contain prokaryotic will be single celled, won't have any nuclear or membrane bound organelles, and will have a single circular chromosome. Eukaryotic cells can be unicellular,or multicellular, they contain a nucleus, and have more chromosomes.
Well first you have to recognize the difference in the two cells. Prokaryotic cells contain a Nucloid instead of a Nucleus, which Eukaryotic cells do. With this understanding, you can use a microscope to locate the difference.
Matt Aponte pr. 4
The main differences between the two types of cells is that eukaryotic cells have a nucleus, prokaryotic cells don't. So i would examine both cells and look at them carefully and see if the material and look if it's old or recently made.

Under a microscope, i would see if the cell has a nucleus and which one has a nucleus region. Then i will see which one has a cell wall.

I would probly cut it open if it had a cell wall then I would know it was prokaryotic and if it had a cell membrane I would know it was eukaryotic cell .

If i was a scientist i would place the cell under a microscope and i would cut it open. If it had a nucleus it would be a eukaryotic cell. If it didn't it would be a prokaryotic cell.

To figure out if the living thing is a PROKARYOTIC or EUKARYOTIC cell I would proceed in collecting samples from the living thing and find out if the samples contain either cytoplasm, DNA, unicellular structure, a cell wall surrounding the cell membrane and no nucleus to be a Prokaryotic cell, or i will see if the samples contain cytoplasm, DNA, a unicellular or multicellular structure, cell wall or no cell wall, a nucleus and membrane bound organelles to be sure it has eukaryotic cells.

In order for any scientist to determine whether the samples contain prokaryotic or eukaryotic cells is by first checking to see if the cell has a nucleus or not. If it does not then it is prokaryotic. Also to determine between the two i would check to see which cells was more complex. The more complex one would be the eukaryotic cell.

Period 4
To find out whether the cell was eukaryotic or prokaryotic, I would have to look at the cell very closely to see what it contains. If it has a cell wall surroinding the membrane and no nuclues, then it is prokaryotic. A eukaryotic cell would be the opposite, since it has no cell way, but it has a nucleus.
Michelle Rivera

To determine if the samples contain either Prokaryotic or Eukaryotic cells I'd have to place it under a microscope and possibly open a cell. When i open the cell i can look at every characteristic the cell has. If the cell has nucleoid region than it is a prokaryotic cell, but if it has a nucleus than its a eukaryotic cell.
