1. Purpose of the Cell Cycle

2. Cell Growth and Division
Cell division occurs in all living organisms
2 Types of living organisms
Prokaryotes-unicellular organisms
Bacteria
Eukaryotes- multicellular organisms
Plants and animal

3. DNA and Chromosomes
Genetic material of a cell contains information needed for the cell’s growth and other activities.
Genetic material in cells is DNA.
Deoxyribonucleic acid
DNA is a chemical that contains information for an organisms growth and functions.
It’s the blueprint of an organism.
Found in the nucleus (center) of the cell

4. DNA and Chromosomes Chromosomes are a structure made of DNA.
Chromosomes are only visible during cell division.

5. Prokaryotes reproduce through cell division
Prokaryotes ( unicellular) organisms reproduce by cell division

6. Cell division in Eukaryotes
Eukaryotes use cell division for specific function in an organism.
Cell division is involved in
Growth- how an organism gets larger
Development- makes specialized cells like nerve cells
Repair- heals wounds and injuries
Reproduction- creates sex cells for sexual reproduction.

7. Cells grow, develop and repair
Growth
Large organisms has more cells
Small organisms have less cells

8. Development
Cells develop and become specialized to perform specific functions
Skin
Nerve
Muscle
Liver
Can you think of more?

9. repair
Cells help an organism body repair injury through cell division

10. Reproduce Cellular division allows cells to reproduce
Asexual reproduction
Create an identical copy of itself.
Example bacteria (prokaryotes)
Cellular division create sex cells for organisms using sexual reproduction.
Sexual Reproduction
Create non-identical organisms
Example: mammals
