Which of the following plants do cross pollination?
Papaya
Grass
Pea
None of the above
Cross-pollination can occur between papaya plants. While some papaya varieties are hermaphroditic and can self-pollinate, others are dioecious, with separate male and female plants. Cross-pollination is required for fertilization and fruit development in dioecious cultivars. Insects such as bees, wasps, and butterflies pollinate papaya plants, although they can also be cross-pollinated by wind or by hand if necessary. As a result, depending on the variety and the circumstances, papaya is an example of a plant that can experience cross-pollination. Hence option 1 is the correct answer.
