1. CELL DIVISION

2. DeoxyriboNucleicAcid
long molecule
double helix shape
contains genetic code (how the body 
​looks and works) of the organism
in nucleus of cell

3. 2 types of cell division:
 1. Mitosis
 2. Meiosis

4. MITOSIS - reproduction (1 cell 2 identical cells) - growth
- regeneration

5. MEIOSIS and Sexual ​Development
- production of gametes (sex cells; 
​spermatozoa in males and ova in females)
- advantages: blending of genes from both parents, differences between descendants 
​and their parents

6. Meiosis (gamete production)
Fertilization (sexual reproduction)
