Question

State the condition and plant that prevents both autogamy and geitonogamy in this plant.

• A. Male and female plants mature at different times – Hibiscus
• B. Male and female flowers on the same plant – Gloriosa
• C. Separate male plant and female plants – Papaya
• D. Male and female flowers on the same plant with different heights – Datura

Hint:

Dioecy is the condition in which a species has separate male and female individuals, thus avoiding self-pollination.

Answer 1

The Correct Option is C

Papaya is a dioecious plant, meaning it has separate male and female plants. This condition prevents both autogamy (self-fertilization within a flower) and geitonogamy (transfer between flowers on the same plant), ensuring only cross-pollination.
