1. Cell Division What are the functions of cell division?
What happens during the cell cycle?

2. Cell Division
three functions of cell division are growth, repair, and reproduction
Asexual reproduction – when a single celled organism reproduces through cell division
Sexual reproduction – cells from two parents combine and cell division occurs

3. What happens during the cell cycle?
A Cell grows(Interphase), prepares for division(Mitosis), and divides into two new cells(Cytokinesis), which are called daughter cells

4. Interphase During interphase the cell grows to full size
Replication – cell makes an exact copy of its DNA
Chromosomes – threadlike structures made of DNA and proteins in the nucleus
In Animal Cells, the centrioles are duplicated

5. Mitosis
The cells nucleus divides into two new nuclei and one set of DNA is distributed to each daughter cell
Prophase
Metaphase
Anaphase
Telophase

6. Chromosomes condense into shapes that can be seen under a microscope
Prophase
Chromosomes condense into shapes that can be seen under a microscope
Chromatids – two rod-like parts of a chromosome

7. Metaphase
Each chromosome attaches to a spindle fiber at its centromere
Chromosomes line up on the metaphase plate

8. Anaphase

9. Telophase

10. Cytokinesis
In animal cells, cell membrane squeezes together
In plant cells, a structure called a cell plate forms across the middle
