a. cross-pollination involves human transfer of pollen from one flower to another.
b. cross-pollination occurs when pollen fertilizes female egg cells on the same flower.
c. cross-pollination results in a flower having only one plant as a parent.
d. cross-pollination occurs when pollen from the flower on one plant fertilizes the egg cells of a flower on another plant.

Explanation:

Hello!

Let's solve this!

Cross pollination is a type of pollination that occurs when the female and male part of the plant is on different sides or when they leave at different times on the same plant.

After the analysis, we will conclude that the correct answer is option B. Cross-pollination occurs when pollen fertilizes female egg cells on the same flower.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
