The document discusses different types of reproduction in multicellular and unicellular organisms. It explains that asexual reproduction involves one cell splitting into two identical offspring through processes like binary fission or budding. Sexual reproduction involves the combination of two different gametes, male sperm and female eggs, which produces offspring with a mix of traits from both parents. Sexual reproduction can involve either internal or external fertilization of the eggs by sperm.

1. UNDERSTANDING
REPRODUCTION

2. Multicellular
Organisms?
Eukaryotes?

DO ALL ORGANISMS
REPRODUCE SEXUALLY?
Insects?

Plants?
Unicellular
Organisms?

3. Asexual Reproduction
One cell becomes two
Offspring are identical to the parent

4. Binary Fission
process where one cell splits into two cells

5. Budding
new offspring grows out of the side of the parent

6. Regeneration
process where an organism regrows parts like a
lizard's tail, starfish, or planaria
Skin Cells
Liver Cells

7. Sexual Reproduction
Two sex cells (Gametes) combine
Female Gamete: ovum or egg
Male Gamete: sperm
Offspring produced are similar to the parents

8. Which images reproduce Sexually?

9. Fertilization
Gametes can combine in or outside of the female
Internal Fertilization: occurs when sperm and egg
combine inside of the female
External Fertilization: occurs when sperm and egg
combine outside of the female
Can you think of examples of each
type of fertilization?

10. Internal Fertilization

11. External Fertilization
Occurs in aquatic
environments
Produces numerous offspring
Describe one drawback
and one benefit
of this process.
