DENDROLOGY

Detailed explanation-1: -Pollination is simply the transfer of pollen grains from an anther to a stigma . Fertilization occurs much later when the pollen grains germinate on the stigma and send down a pollen tube which releases the sex cells to fertilize the ovules.

Detailed explanation-2: -The anther usually contains four pollen sacs which are responsible for producing pollen grains. Each pollen grain is a single cell containing two male gametes. Once mature, the anther splits open and pollen is released.

Detailed explanation-3: -Once pollen gets to the ovary within the flower, the ovary develops into a fruit. The ovules inside the ovary develop into seeds inside of this fruit.
