In castor and maize plants, _________
Updated On: Apr 18, 2024
- both autogamy and geitonogamy are prevented
- the anthers and stigma are placed at different positions to encourage cross pollination
- autogamy is prevented but not geitonogamy
- male and female flowers are borne by different plants
Hide Solution
Verified By Collegedunia
The Correct Option is C

Sexual Reproduction in Flowering Plants
Sexual reproduction in flowering plants takes place or happens when the production of a new organism occurs from two parents by making use of their gametes or sex cells. Both sexual and asexual reproduction can be found in plants. Nearly all flowering plants reproduce sexually. Flowers play a captious role in the process as it carries both the male and female reproductive parts commonly known as androecium and gynoecium respectively.
An individual flower comprises the following parts -
