Solution
The correct option is A Calcium
The correct answer is A.A series of interactions occur between male and female cells and tissues while pollen tubes are elongating through the diploid sporophytic tissue of the pistil. It is these interactions that ensure the pollen tube enters the embryo sac and that both deposited sperm cells fuse with the egg and central cell successfully. The role of the calcium ion in these interactions has received particular attention, as it appears to provide a universal signal with pleiotropic effects on attraction, long and short-distance communication, cellular fusion, and cell signaling.
