Cell Cycle and Cell Division
Part 1: Cell Cycle - The diagram below shows an overview of the cell cycle and mitosis.
1. Label the diagram below using the following terms: cytokinesis, M phase, Interphase, G 1
phase, G2 phase, S phase, mitosis
2. Draw a STAR in the part of the diagram where DNA replication occurs.
The Cell Cycle
Part 2: Mitosis – The diagram below represents basic cell division via mitosis with one parental
cell dividing into two daughter cells.
In each circle, write the following:
A. the number of chromosomes for human cells
B. whether the cell is diploid or haploid
C. whether the cell should be designated 2n or n
1. First, identify the name of each of the stages of mitosis on the diagrams below.
2. Then write the following phrases below the correct picture to describe what happens in each
stage.
