Study Notes
- Sexual reproduction in plants: Flowers are reproductive organs bearing male (stamen) and female (pistil) parts
- Bisexual flowers: Contain both male and female parts (ex: rose, China rose)
- Unisexual flowers: Contain either male or female parts (ex: gourd, pumpkin)
- Pollination: Process of transferring pollen grains to female reproductive organs
- Occurs between same type of flowers (self-pollination) or different flowers on separate plants (cross-pollination)
- Agents of pollination: Abiotic (wind, water) and biotic (bees, bats, moths, birds)
- Pollen grain reaches stigma safely
- Fertilization process involves intermediate steps (to be discussed in next video)
