Answer:
The stigma, a female structure which collects pollen and passes it to the ovary
Explanation:
<u>The structure represented by the letter A in the diagram is the stigma.</u>
The <u>stigma of a flower represents part of the female reproductive structure</u>. The surface of a mature stigma is sticky and as such, it is able to attract pollen grains from the anther. A pollen that lands on the stigma germinates and its pollen tube grows through the style of the stigma down to the ovule where one of the sperm cells of the pollen fertilizes the egg cell of the ovule to form a diploid zygote and the other sperm cell fuses with the polar nuclei of the ovary to form a triploid cell that eventually becomes the endosperm.
<em>The sepal and the petal are labeled as D and C in the diagram respectively while the stamen is made up of B and H.</em>
