pollen sac
plant anatomy
Quick Summary
A pollen sac, also known as a microsporangium, is a part of a seed plant's anther where pollen is formed. Within the anther, microsporocytes undergo meiosis to produce microspores, which develop into pollen grains. These pollen grains contain the male gametophyte, essential for sexual reproduction in plants. The pollen sac's primary function is the production and containment of pollen until it is ready for dispersal.12
