Question

Characteristics that promote cross-pollination include all except

• A. the anther and stigma are at different heights
• B. having male only and female only flowers
• C. the anther and stigma is at the same height
• D. the pollen and ovules mature at different times in the same flower.

Answer 1

The correct option is C

the anther and stigma is at the same height

When pollen moves from one plant to another of the same species, it is called cross-pollination. For cross-pollination to occur, the conditions should be such that the pollen grains are able to reach another flower of same species. If the anther and the stigma are at the same height, it will be easier for the pollen grains to reach from the anther to the stigma beside each other. So, this will promote self-pollination very easily.
