Transfer Grain
Angiosperm Pollen and Gamete Competition- Selective Advantage?
I need help with this question:
In angiosperms, an abundance of pollen is transferred by insects to the stigma. Later, pollen grains germinate to produce pollen tubes that race through the style in their bid to fertilize a limited number of egg cells within the ovules. Explain how this process of gamete competition could be of selective advantage.
This process of gamete competition could be of selective advantage to the plant because the pollen tubes that are the most fit to survive are the fastest in their race to fertilize the limited number of egg cells within the ovules. These pollen tubes that are most fit to survive must successfully grow and digest its way down into the ovary of the plant via the style and discharge their sperm into the embryo sac, resulting in the fertilization of the egg.
