1. Asexual & Sexual Reproduction

2. Asexual Reproduction
Type of reproduction in which a new organism is produced from ONE parent and the offspring is identical to the parent.
Occurs in most plants, bacteria, protists, and low invertebrates.
Offspring produced by MITOSIS.

3. Asexual Reproduction One parent
Offspring are identical to the parents.
One Parent
Identical Offspring

4. Asexual Reproduction Types of Asexual Reproduction
Binary Fission – used by bacteria, an organism whose cells do not contain a nucleus copy then divide into two identical organisms
Example: bacteria

5. Asexual Reproduction Types of Asexual Reproduction (cont’d)
Budding – organism that produces a bud that breaks away to live on its own.
Example: hydra

6. Asexual Reproduction Types of Asexual Reproduction (cont’d)
Fragmentation – organism breaks into pieces and each piece becomes new organism.
Example: starfish,
flatworms

7. Asexual Reproduction Advantages and Disadvantages
Advantages – Can produce large numbers of offspring in a short time.
Disadvantages – Lacks genetic diversity, all offspring are identical to parent, less able to adapt to environment.

8. Sexual Reproduction Two parents
Offspring are a combination of both parents and are therefore different from each parent.
unique / diverse offspring
Two Parents

9. Sexual Reproduction Advantages and Disadvantages
Advantages – variety and/or diversity of offspring (color, shape, size, intelligence, ability, etc.), More able to adapt to environmental changes.
Disadvantages – uniqueness, sometimes traits needed for survival are not passed on. There are fewer offspring.
