Vedclass · Answer

(C) The pollen tube enters the embryo sac through the micropyle. Once it reaches the synergids,the tip of the pollen tube absorbs water and nutrients from the surrounding cells. This leads to an increase in turgor pressure within the pollen tube. Simultaneously,the synergids release specific enzymes that weaken the cell wall at the tip of the pollen tube. Due to the high turgor pressure and the enzymatic degradation of the wall,the tip of the pollen tube ruptures,releasing the two male gametes into the embryo sac.

By which process does the tip of the pollen tube rupture within the embryo sac?
