Detailed explanation-1: -Self-pollination is the process of transfer of from anther to the stigma of the same flower or to the stigma of another flower of the same plant. Since unisexual flowering plants have either anther or stigma on all of its flowers, self-pollination is not possible in them.

Detailed explanation-2: -When pollen comes from flowers on the same plant, it’s called self-pollination or “selfing, ‘’ while reproduction involving flowers from two different plants is termed cross-pollination. Seed production after selfing is considerably lower than cross-pollination, and the resulting seedlings are not as healthy.
