| 释义 | pollination (once / 27360 pages) n Use the noun pollination to describe the reproduction of plants, whether it happens with the assistance of insects, other animals, or the wind. Pollination can happen when a bee moves pollen from a plant to another area, helping the plant to reproduce. Plants are fertilized by the transfer of pollen to other parts of the same plant, or to neighboring plants, through pollination. The root word is pollen, used in science writing since 1760 to mean "the fertilizing part of flowers," and earlier to mean "dust or fine flour."
