UNIT 1 REPRODUCTION
Reproduction in Organisms
Reproduction a characteristic feature of all organisms for continuation of species. Modes of reproduction- Asexual and sexual.
Asexual reproduction – Uniparental
- Modes – Binary fission, sporulation, budding, gemmule, fragmentation, regeneration.
- Vegetative Propagation in plants.
Sexual reproduction in flowering plants – Flower structure.
- Development of male and female gametophytes.

- Outbreeding devices.
- Pollen-Pistil interaction.
- Double fertilization
- Post fertilization events
- Development of endosperm & embryo
