Onion root lab
This Onion root lab really helped me not only to understand the types of phases that are in mitosis but also to understand how to identify them. I thought that this would be a complicated task on my part because I didn't think that I could identify a tiny cell and be able to compare it to another tiny cell. This lab helped me to realize that everything in this world will never be the exact same. With the tiny cells we identified yesterday each cell of the onion root had it's own little detail and process. Interphase is a bunched up cell then the process moves on to prophase which is still a bunched up cell but the nucleus is very clear and shows p as a black dot usually in the middle of the cell or close to it. Then Metaphase comes next in the process and you can identify it as the cell slowly separating, then moving on to anaphase where there is a defined divide in the cell. The last stage is Telophase which you can identify the cell because it is divided into two separate parts and looks like halves of egg shells. Learning about the process of mitosis will probably be my favorite part of biology because I feel that even after high school I will remember what I learned about it and how to identify which stage of mitosis is which!
