Explanation: 

Detailed explanation-1: -Pollination is the transfer of pollen grains from an anther to a stigma. Pollen can be transferred by an animal or by the wind. Fertilisation takes place inside the ovary when the nucleus of pollen grain fuses with the nucleus of an ovule to produce a zygote.

Detailed explanation-2: -The most generalized form of this process requires four steps: pollination, germination, penetration of the ovule, and fertilization. After fertilization, the zygote divides to form an embryo. Double fertilization is common in angiosperms.

Detailed explanation-3: -One well-studied example of a moth-pollinated plant is the yucca plant, which is pollinated by the yucca moth. The shape of the flower and moth have adapted in such a way as to allow successful pollination. The moth deposits pollen on the sticky stigma for fertilization to occur later.
