Growth and Reproduction of Cells

7th Grade Science

The cell cycle has 3 parts: Growth Replication Division

The Cell Cycle

During Interphase: The cell grows and goes through life processes Copies genetic material (DNA) Makes protiens

Phase One: Interphase

Phase Two: Mitosis

Mitosis is the replication of the nuclear material

It is a type of asexual reproduction

The 4 Steps of Mitosis

1. Prophase- chromosomes shorten and thicken and become known as chromatids

2. Metaphase- chromatids line up at the center of the cell.

3. Anaphase- chromatids separate from each other and move to opposite side of the cell.

4. Telophase- a new nuclear membrane forms around each region of chromosomes.

Phase Three: Cytokinesis

The final stage in the cell cycle is cytokinesis

Here two identical daughter cells are formed
