Study Notes
- Sexual reproduction in plants occurs through the fusion of male and female gametes.
- The flower, the reproductive organ, contains both male (stamen) and female (pistil) parts.
- Bisexual flowers possess both male and female parts, examples include rose and China rose.
- Unisexual flowers possess either male or female parts, such as gourd and pumpkin flowers.
- Pollination is the first step in sexual reproduction, and involves transferring pollen grains from the anther to the stigma.
- Pollination occurs between flowers of the same type, and can be self-pollinated (on the same plant) or cross-pollinated (between different plants).
- Agents such as wind, water, bees, bats, moths, and birds aid in pollination.
- Fertilization does not occur directly after pollination, there are intermediate steps.
