Author: Created by TheEducatorsCorner. The seedling grows further and ultimately forms a new plant. The process in which a seed begins to grow is, coat splits, a tiny root grows downward and a shoot. After fertilisation, the ovary of a flower develops and becomes a fruit (with seeds inside it). When an insect sits on the flower of a plant for sucking nectar, then the pollen grains from the anther of this flower stick to its body. They get stuck to the fur of animals and thus get spread to different places. They can repeat the lessons as many times as required. The pollen tube enters the ovule in the ovary.The tip of pollen tube bursts open and male gamete comes out of pollen tube.In ovary, the male gamete of pollen combines (or fuses) with the female gamete present in ovule to form a fertilised egg cell called zygote. Are produced in structures made of haploid cells.
