Question

Which condition is displayed by Ray florets of Sunflower to favour cross pollination?

Answer 1

Answer:

Sunflowers require a pollinator (bees) to move pollen from one flower to another. Unlike corn and other crops, very little pollination is accomplished by wind. Sunflower pollen is heavy and stick and most of it ends up on the leaves of the plant during windy days.

Explanation:

While the ray florets cannot reproduce on their own (indeed, they lack any sex organs at all), the disc florets have both male and female sex organs. This allows the flower to self-pollinate, producing an offspring that is an exact match to the original.
