Mitosis Virtual Lab

1. Which stage does the following occur

Chromatin condenses into chromosomes: Prophase

Chromosomes align in center of cell: Metaphase

Longest part of the cell cycle: Interphase

Nuclear envelope breaks down: Prometaphase

Cell is cleaved into two new daughter cells: Cytokinesis

Daughter chromosomes arrive at the poles: Telephase

2. The colored chromosomes represent chromatids. There are two of each color because one is an exact duplicate of the other.

- How many chromosomes are visible at the beginning of mitosis? 4

- How many are in each daughter cell at the end of mitosis? 4

- The little green T shaped things on the cell are: Centrioles

- What happens to the centrioles during mitosis? They move to the poles of the parent cell.

3 . Identify the stages of these cells:

a) Interphase

b) Metaphase

c) Telephase

Classify the 36 cells:
