Everything is either a Prokaryotic Cell or an Eukaryotic Cell. Each of these are responsible for different things and have different characteristics. But they also share similar things:

All cells, whether they are prokaryotic or eukaryotic, have some common features.
Common features of prokaryotic and eukaryotic cells
The common features of prokaryotic and eukaryotic cells are:
1. DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes

2. Plasma membrane, a phospholipid bilayer with proteins that separates the cell from the surrounding environment and functions as a selective barrier for the import and export of materials

3. Cytoplasm, the rest of the material of the cell within the plasma membrane, excluding the nucleoid region or nucleus, that consists of a fluid portion called the cytosol and the organelles and other particulates suspended in it

4. Ribosomes, the organelles on which protein synthesis takes place

It was really good and you diagrams were very helpful in understanding you blog. I thought that the main points were that there were two types of cells, and how they were similar and different.

I really like how you explained all this lacie! I do agree with Ariel the last picture is a little blurry but I enjoyed reading your blog =)

yaya i found a site i really like that helped me out a lot! it broke the structure of the cell down into 3 categories then broke it down even more within those categories it was straight down to the point and helped me remember all the parts.

In this website, I thought it interesting, yet simple. Check it out for yourself. :) I couldn't find any credibility on it, though. But when I went to the homepage, it came from a secondary school. That's as far as I could go regarding credibility…

I feel kind of lame having the last three posts on this! But Aziz and I had a discussion and it turns out our video is kind of the same! Mine has the music and a newscast, while whoever did Aziz's took the animation and narrated it. So I thought I w…

A very interesting argument that suggests taking action to avoid any potential global climate crisis.

Now I can see this post, but not the other one where I put on the picture and claimed that this post was gone. What's going on?!? I also know Ivory posted after this one...and I saw both mine and Ivorys in class. Hmmm...

I like your pictures Laci :)

When I started my research I searched for “cellular structure and function” and even know Mr. Nash said not to just choose the first thing that pops up, but in this case the first two links that popped up were the same website called Cellular Biolog…

I was ultimately against posting a video, and doing an actual website.. BUT I really love this video from Harvard. It shows you what goes on inside the cell. It's set to beautiful background music, and I think it shows how much "art" is really insid…
