Flashcards
External Fertilization
External Fertilization
Sperm swim to eggs released into water; many gametes produced, but few fertilized.
Internal Fertilization
Internal Fertilization
Fertilization occurs inside the female's body.
Courtship

Study Notes
Fertilization
- Joining of male and female gametes
- Ovary becomes the fruit, protecting the seed
- Ovules become seeds
Reproductive Strategies
- Behaviors during reproduction to ensure offspring survival
- Courtship behavior of males and females
- Three functions:
- Recognize the same species
- Ensure both are ready to mate
- Assess the health and strength of others
Types of Fertilization
- External:
- Sperm are motile (can move) and swim to the egg
- Eggs and sperm released into water
- Many gametes produced, but few are fertilized
- Examples: frogs, fish, some worms, jellyfish, sponges
- Internal:
- Eggs fertilized inside the female's body
- Most have an organ to place sperm inside the body
