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)
Learn about the reproductive organs of plants, the difference between bisexual and unisexual flowers, the process of pollination, and the agents involved in pollination. Understand how pollen grains reach the stigma and the intermediate steps involved in the fertilization process.
