         Today I will blog about the process of Mitosis. Mitosis is when one cell becomes two cells. It begins when the DNA in the cell start to coil up. Then they merge together to make chrommosomes. Then outside the cell wall these things circle around it and make protien for the chromosomes. There is one part of this process that scientists don't know. They do not know why the nuclear membrane dissolves. Later it is regenerated or comes back. Next some spindals came and attach themselves into a cetain part of the chromosomes. Then the spindals pull the chromosomes to different sides of the cell. Now the Nuclear Membrane comes back. The spindals keep pulling to different sides.

     In my science class we are learning about animal and plant cells. We have learned alot about the cells. In science I got to look at some plant cells through a microscope. Plant cells and animal cells have almost the same structures. They also have different structures as well. One important one is the Ribosome. They both have this and it provides protien. One cell they do not have in common is the vacule. I think that animal cells do not have that. Another thing is that they both have a cell wall. Yesterday we watched on Brainpop videos about animal and plant cells and structures.

   Today I will tell you what I learned from a science project I did. The science project was called edible science. In this project I learned a lot about the cell. To do this project my group and I had to make a cell out of cake and candy. It was a lot of fun. In this project I learned about some cell parts. I learned what they did and how that part is important to the cell. I also learned how to work as a team with my group. In this project I learned about some parts of the cell like the vacule, the ribosome, and the nucleus. When my science teacher, Mrs.Poole, came to grade she asked us a lot of questions on the cell. Only two people in my group got the answers right and got a little extra credit.
