Mitosis/Meiosis Review Sheet Name ______
The Cell Cycle
1. Label the diagram below with the phases of the cell cycle.
2. Based on the following descriptions, name the phase from the
cell cycle.
a. Sister chromatids separate and start to move apart.
b. The cytoplasm tears apart. The nuclear membrane is intact.
Chromosomes are no longer visible.
c. Chromosomes line up in the middle of the cell. Each
chromosome is connected to a spindle fiber.
d. This phase cannot be seen. The cell grows, synthesizes
more DNA(replication), and grows more.
e. Nuclear membranes start to reform, the nucleus tears apart.
f. Mitosis begins. The chromosomes become visible,
centrioles separate, spindles form, nuclear envelope breaks
down.
