The three phases of Cellular Division:

-Cell Cycle

-Mitosis

-Meiosis

Cell Cycle

The Cell Cycle is the cycle of growth and asexual reproduction of a cell, consisting of interphase followed in actively dividing cells by prophase, metaphase, anaphase, and telophase.

1) How many steps are there in the cell cycle?

2) What are the names of the phases?

Mitosis

-Mitosis is a type of cell division that results in two daughter cells

-Each having the same number and kind of chromosomes as the parent nucleus

6) How many steps are there in Mitosis?

Meiosis

-Meiosis is a type of cell division that results in four daughter cells

-Each have half the number of chromosomes of the parent cell
