The Cell Cycle
From the moment a new body cell is formed, it begins its journey in the cell cycle. This journey
consists of a series of stages, or phases. Fill in the blanks below, using the word bank provided (next
page), in order to tell the story of a cell’s journey.

Compare Mitosis and Meiosis
Contrast between mitosis and meiosis by providing four (4) differences between the two types of
division.
Mitosis
Growth and repair of body cells.
Meiosis
Formation of gametes.
Occurs in body cells.
Occurs in sex cells.
1 division.
2 divisions.
Results in 2 diploid, genetically identical
cells.
Results in 4 haploid, genetically different
cells.
