Answer:
A pollen grain is transferred from an anther to the stigma of the same flower
Step-by-step explanation:
The statement "A pollen grain is transferred from an anther to the stigma of the same flower" best describes an interaction that will allow a flowering plant to reproduce by self-pollination.
Self-pollination occurs when pollen from the male reproductive structures (anthers) of a flower is transferred to the female reproductive structures (stigma) of the same flower, or to another flower on the same plant. In this case, the statement describes the transfer of pollen from an anther to the stigma of the same flower, which is a form of self-pollination. The other statements describe interactions that involve transferring reproductive structures or pollen grains to different flowers or plants, which would result in cross-pollination rather than self-pollination.
