Answer:
1)Transfer of pollen grains from anther to stigma is termed as Pollination.
2)When sperms come in contact with an egg, one of the sperms may fuse with the egg. Such fusion of the egg and the sperm is called fertilization.
4)A seed is formed when fertilized ovule divides by mitosis.Thus fertilization takes place and so formed zygote divides and develops into an embryo. Following the fertilization, every part of the flower sheds off except ovary. The ovary of the flower develops into the fruit while ovules develop into seeds.
