Question

1. a flower that has both male and female reproductive structures is shown. which statement best describes an interaction that will allow a flowering plant to reproduce by self - pollination? an anther is transferred from a filament to another filament within the same flower. a pollen grain is transferred from an anther to the stigma of the same flower. an ovule is transferred from the ovary to a petal on a different flower. an ovary is transferred from a flower on one plant to a flower on a different plant. clear all

Explanation:

Self - pollination occurs when pollen from the anther of a flower is transferred to the stigma of the same flower. This allows the plant to reproduce without relying on external agents (like insects or wind) to transfer pollen between different flowers or plants.

• Option 1: Transferring an anther from one filament to another within the same flower is not pollination. Pollination is about pollen transfer, not anther transfer.
• Option 2: When a pollen grain is transferred from an anther to the stigma of the same flower, this is self - pollination.
• Option 3: Transferring an ovule from the ovary to a petal on a different flower is not a part of the pollination process. Pollination is specifically about the transfer of pollen.
• Option 4: Transferring an ovary from one plant to another is not pollination. Pollination is related to the transfer of pollen for fertilization.

Answer:

A pollen grain is transferred from an anther to the stigma of the same flower.
