Title: Reproduction and Development
1Reproduction and Development
2Asexual reproduction
- Fission
- Budding
- Gemmules
- Fragmentation
- regeneration
3Sexual reproduction
- Parthenogenesis
- Hermaphroditism
- Sequential hermaphroditism reverses its sex
during its lifetime - -protogynous female first
- -protandrous male first
4Fertilization
- External vs. internal
- External requires water environment
- Internal allowed animals to adapt to dry land
- Incited by pheremones
