Where does grass pollen go when it gets to the other flower?

When grass pollen reaches another flower, it typically lands on the stigma, the receptive part of the female reproductive structure. If the pollen matches the flower's compatibility requirements, it germinates and forms a pollen tube that extends down into the ovary. This allows sperm cells carried by the pollen to travel down the tube and fertilize the ovules, leading to seed development. Thus, the pollen plays a crucial role in the reproduction process of flowering plants.
