Question

How is papaya able to prevent both autogamy and geitonogamy?

Answer 1

Papaya plant:

1. Papaya plants belong to the group angiosperms (plants with seed-bearing fruits).
2. They are dioecious (male and female flowers in separate individuals).
3. Geitonogamy is the process by which the pollen of one flower fertilizes the ovule of another flower on the same plant.
4. Whereas, autogamy is the process of self-fertilization where the pollen of one flower are transferred to the ovule of the same flower.
5. Therefore, as papaya plants are dioecious hence they can prevent both geitonogamy and autogamy.
