Answer 1

Pollination is the transfer of pollen to the female organs of seed plants. In flowering plants (angiosperms, or "covered seeds"), immature seeds (ovules) are located within carpels. In contrast, nonflowering seed plants have uncovered ovules to which the pollen is transferred, making these "naked seeds" (gymnosperms).
