Pollen grains from the male reproductive structures of flowering plants (stamens) land on the female reproductive structure (pistil) during the process of pollination. The pollen typically comes from the same species, as this ensures compatibility for fertilization. When the pollen grain adheres to the stigma of the pistil, it germinates and grows a pollen tube down to the ovary, allowing sperm cells to reach and fertilize the ovules. This process is crucial for the production of seeds and fruit.
Microspores mature into pollen grains in seed plants as part of the process of microgametogenesis. Pollen grains play a crucial role in the reproductive cycle of plants by carrying male gametes to the female reproductive structures.
The sticky or hairy stalk that captures pollen grains is called the stigma. This structure is part of the female reproductive organ of a flower and plays a key role in the pollination process by trapping pollen grains that land on it.
A flower's sperm is contained within the pollen grains. These pollen grains are produced in the male reproductive organs of the flower, called the stamens. When the pollen grains are transferred to the female reproductive organs of another flower, they can fertilize the ovules and lead to seed development.
An anther is the male reproductive structure of a flower that produces pollen. Pollen grains contain the male gametes of plants and are essential for the process of pollination, where the pollen is transferred to the stigma of a flower for fertilization to occur.
The part of a flower that has a sugary substance for receiving pollen grains is the stigma. The stigma is the sticky top part of the pistil, which is the female reproductive structure of the flower. It serves as a receptive surface for pollen, facilitating the process of pollination. The sugary substance helps attract pollinators and encourages the transfer of pollen grains.
The transfer of pollen grains to the female reproductive structure, the pistil, is called pollination. This transfer can be mediated by the wind.

The process of pollination.
Pollen grains come in contact with the ovule through the stigma, which is the receptive tip of the female reproductive organ (pistil) in a flower. Pollen grains germinate on the stigma, form a pollen tube, and then grow down to the ovule for fertilization.

Matured pollen grains contained sperm cells. When Pollen grains are sticky, you have pollen. Pollen grains are contained in the pollen sac, with the purpose of helping plants reproduce.

No, pollen grains are not formed within the stigma. Pollen grains are formed in the anthers of a flower's stamen. The stigma is part of the female reproductive structure of a flower, where pollen grains land and germinate to fertilize the ovules.
