Stamens of a Hippeastrum with white filaments and prominent anthers carrying pollen
The stamen (plural stamina or stamens) is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium.[1]
Answer:
Stamen will decay, but the pollen does not because of the presence of the outer wall of pollen which is a resistant structure.
Explanation:
Pollen grains constitute layers of protective coverings around them. The inner covering is called the intine and the outer covering is called the exine. The exine is a very durable and resistant structure. It is capable of resisting intense heat, strong acids, or bases. It is very difficult to rupture or disintegrate this covering. Moreover, there is an intine layer too. Due to these coverings, pollen is never subject to decay. This is why the pollen grains are easily preserved and conserved for long.
The stamen is the male reproductive structure that produces pollen. Stamens do not have any covering around them. They are simple structures with only a single function of producing pollen. Thus, stamens are very easily decayed, unlike pollen grains.
