Objective: What is the difference between sexual and asexual reproduction

Do Now: When you fall and scrape your knee, what happens to the cut over time?

• The production of offspring from one parent.

• Results in offspring that are genetically identical to the parent.

Mitosis

• Cells create new cells by dividing in two through a process called mitosis

• Used to grow and repair damaged tissues

Binary FissionBinary Fission: one organism

divides itself into 2 which results in 2 genetically identical organisms

Budding

Budding: a bud is produced by the parent, breaks off and grows into a new, genetically identical organism

Spore FormationSpore Formation: Spores made by mitosis

develop into a new organism after dispersal (Ex: fungus, algae)

Regeneration

If an organism loses a body part, it can regrow that part

Sexual Reproduction - 2 parents are involved in the production

of offspring

- Genetic material from each parent combines producing genetically different offspring
