Onion root mitosis lab
For this lab, we mostly talked about mitosis and how it plays a key role this process. The Onion root cell was a general lab. This lab was to help classify the different stages of mitosis. After a few picturesThe Onion root cell was general lab. This lab was to help classify the different stages of mitosis. After a few pictures I could identify the different stages when i looked at it. The stages of mitosis are, Interphase, Prophase, Metaphase. Anaphase, and Telophase.Thing that helped me identity each stage was by looking close at where the chromosomes were located. For Interphase you can see the nucleus this is the only stage you can see it because its really dark. In prophase the chromosomes are starting to move all over the place. In Metaphase the chromosomes are usually in a line in the middle. During anaphase they are pulling a part from each other. And during telophase is when they are separated into two different sections usually top and bottom. Along with this lab I also did a lab looking through the microscope to identify the different stages of mitosis. The slide I looked at was also an onion root cell. After looking threw the microscope we had to count all the stages of the onion root cell. When we were done we tallied up all the different stages that we did and put it on this graph that is below. You can see that one really stood out when we did this, and it was interphase that was 80% of this whole graph. So looking at the graph i could see that the interphase was the most common stage in this onion root cell.
