Answer 1

Answer:

Pollen grain from anther of one flower that reaches the stigma of another flower is called…Cross Pollination…

Pollen is the male reproductive part of a flower that the stamen bears. Stigma is the female reproductive part of a flower that acts as a receptor to pollen.

When there is a fertilisation in flower occuring due to the transfer of pollen to the female part stigma, it is called cross pollination. The seed hence formed will be genetically identical to two plants and will give a mixed phenotype.

Answer 2

Pollen grain from anther of one flower that reaches stigma of another flower is called cross pollination.

Explanation:

The pollen grains have male gametes of plants inside them, that are produced in anthers.

Stigma, on other hand, is receptacle of flower where pollen grains do land.

The "process of transfer of pollen" from "anther of any specific flower to stigma" of either same flower or other flower is called cross-pollination.

As here, pollen is transferred from "anther of any one flower to stigma" of a different flower, its cross-pollination.
