stamen
a flower produce pollen sacs which has pollen grains in it
Microspore mother cell after undergoing meiosis produces pollen grains, and the pollen grains during germination produce sperms by undergoing pollen mitosis.

Stalks are structures that support the pollen grains in flowers. They connect the pollen grains to the anther, where the pollen is produced, and help in the dispersal of pollen for plant reproduction.
microsporangium
pollen grain
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.

Pollen
The size of pollen grains can vary depending on the plant species, but most are typically between 10 to 100 micrometers in diameter. Some larger pollen grains can reach up to 200 micrometers. Pollen grains are microscopic structures produced by seed plants for reproduction.
Pollen sacs are structures found on the anthers of flowers in which pollen grains are produced and stored. They are typically small, oval-shaped structures that contain numerous pollen grains. Pollen sacs can vary in color, size, and texture depending on the plant species.
The anther produces pollen grains which would be transferred to other plant's stigma which will receive the pollen grains when an insect fly pass it then the pollen grains will be stuck on its wings.
