(B) The cytoplasm of pollen grains has a high concentration of solutes compared to water or a dilute sugar solution.When placed in these hypotonic environments,water enters the pollen grains due to the process of endosmosis.As a result,the internal turgor pressure increases significantly,causing the pollen grains to swell and eventually burst.

Pollen grains of some plants germinate on the stigma soon,but they burst in water or a dilute sugar solution. Why?
