Question

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 ovary is transferred from a flower on one plant to a flower on a different plant.
an ovule is transferred from the ovary to a petal on a different flower
a pollen grain is transferred from an anther to the stigma of the same flower.
an anther is transferred from a filament to another filament within the same flower.

Explanation:

Self - pollination in flowering plants is the transfer of pollen from the anther (male part) to the stigma (female part) of the same flower or another flower on the same plant. Let's analyze each option:

• Option 1: Transferring an ovary between different plants is not part of self - pollination; self - pollination is about pollen transfer, not ovary transfer.
• Option 2: Ovules are not transferred to petals for pollination. Pollination involves pollen and stigma interaction.
• Option 3: Transferring a pollen grain from an anther to the stigma of the same flower is the definition of self - pollination.
• Option 4: Anthers are part of the male structure and are not transferred between filaments for self - pollination; self - pollination is about pollen moving to the stigma.

Answer:

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