Homework Answers
1. In plants, as in all eukaryotic life-forms, the cell cycle comprises the processes of cell division, constituted by three preparatory phases (G1 , G2 , and S), followed by mitosis (nuclear division) which has 4 phases prophase, metaphase, anaphase, telophase and finally cytokinesis (cytoplasm division).
2. In animals, as in all eukaryotic life-forms, the cell cycle comprises the processes of cell division, constituted by three interphases phases (G1 , G2 , and S), followed by Mitosis with prometaphase & cytokinesis together define the mitotic (M) phase of an animal cell cycle.

PART 1: How Long Do Cells Spend in Each stage of Mitosis? In this activity, you will be presented with cells from the tip of an onion root. You will classify each cell based on what phase it is in. At the end you will count up the cells found in each phase and use those numbers to predict how much time a dividing cell spends in each phase. You can base your calculation on a...
