What is the difference between self-pollination and cross-pollination?

Question 2 options:

Self-pollination leads to the creation of a fruit. Cross-pollination does not.

During cross-pollination, ovules are carried from one plant to another plant ... During self-pollination the ovules stay on the same plant. During cross-pollination, ovules are carried from one plant to another plant ... During self-pollination the ovules stay on the same plant.

During cross-pollination the pollen grains are carried from one plant to another plant. During self-pollination the pollen and ovules are from the same plant.

During cross-pollination, the pollen grains travel from the stigma to the anthers. During self-pollination, the pollen grains travel from the anthers to the stigma.

The correct answer is that during cross-pollination the pollen grains are carried from one plant to another plant. During self-pollination, the pollen and ovules are from the same plant.

In self-pollination, the pollen from the anther is deposited on the same flower's stigma, or on the stigma of another flower of the similar plant. In comparison, out-crossing or cross-pollination results in greater genetic diversity as the pollen grains and ovules are obtained from different plants.
