multiple choice question
after a pollen grain lands on a
________ of the correct species, a
________ grows through tissue of the style toward the ovary.
o anther; microspore
o stigma; microspore
o stigma; pollen tube
o anther; pollen tube

Explanation:

When a pollen grain lands on the stigma (the receptive part of the female reproductive structure in a flower) of the correct species, it germinates. A pollen tube grows out of the pollen grain. The pollen tube then grows through the style (the stalk connecting the stigma to the ovary) towards the ovary. The anther is part of the male reproductive structure (produces pollen, but the pollen tube does not grow from the anther). Microspore is an early - stage cell in pollen development.

Answer:

stigma; pollen tube
