1. Notes on mitosis & Meiosis

2. Reproduction
Reproduction - is the act or process of producing babies, young animals, or plants. Living things reproduce to make young plants or animals.

3. Questions for discussion:
Do all organisms reproduce?
Do all organisms reproduce in the same way?

4. Types of Reproduction
Asexual - one parent
Sexual - two parents

5. Asexual reproduction: a type of reproduction in which a new organism is produced from one parent and has the same DNA or genetic material as the parent.
Spider plant offspring
Yeast cells dividing (budding)

6. How do little elephants grow up to be BIG elephants?

7. Why do animals shed their skin?

8. The process of asexual reproduction begins after fertilization
The process of asexual reproduction begins after fertilization. (after a sperm fertilizes an egg).

9. Three reasons why cells reproduce by asexual reproduction: 1. Growth 2
Three reasons why cells reproduce by asexual reproduction: Growth Repair Replacement
Skin cancer - the abnormal growth of skin cells - most often develops on skin exposed to the sun.
Cell that reproduce by asexual reproduction reproduce constantly.

13. Sexual reproduction: a type of reproduction in which two cells, usually an egg and a sperm join to form a zygote, which develops into a new organism with its own genetic identity.
Animal
Plant

14. Meiosis Cycle

15. Question for discussion:
Can you think of other organisms that reproduce through asexual or sexual reproduction?

16. Asexual Reproduction Examples

17. A whole new starfish can grow from a single arm that was cut off a starfish organism.
A planarian is a tiny flatworm that lives in ponds. If a planarian is cut into pieces, each piece will grow into a new planarian.
Yeast are one-celled organisms that produce offspring from a bulge that forms and breaks away from the parent.

18. A paramecium is a one-celled organism that reproduces by splitting in half to become two new cells.
An ivy plant will reproduce a whole new plant if a piece of stem and leaf is placed into water or soil.

19. Review – Life Cycle – Organisms
CHARACTERISTICS OF CELLULAR SEXUAL REPRODUCTION (MEIOSIS )
One parent
No genetic variation (genotype and phenotype similar)
Quick method of reproduction
Examples fission, budding and vegetative reproduction.

20. Review Life Cycle - organisms
CHARACTERISTICS OF CELLULAR ASEXUAL REPRODUCTION (MITOSIS)
Two parent
Variety in offspring
Allows for adaptation for survival
Examples: Most plants and animals
