pistil
anther
in an angiosperms life cycle, when does pollination occur?
when the flower makes pollen
when the pollen lands on the pistil

Explanation:

Pollination in angiosperms is the transfer of pollen from the anther (male part) to the pistil (female part) of a flower. The first option, "when the flower makes pollen", refers to pollen production (microsporogenesis), not pollination. Pollination occurs when pollen (from anther) is transferred and lands on the pistil, matching the second option.

Answer:

when the pollen lands on the pistil
