Detailed explanation-1: -In a process called fertilisation, the two gametes join and their chromosomes combine, so that the fertilised cell contains a normal complement of chromosomes, with some from each parent flower. The fertilised ovule goes on to form a seed, which contains a food store and an embryo that will later grow into a new plant.

Detailed explanation-2: -When the sperm cell from the pollen grain reaches the ovary or ovule the sperm joins with the egg. This is called fertilization.

Detailed explanation-3: -Fertilization occurs as a sperm cell in a pollen tube fuses with the egg cell of an ovule, resulting in a plant embryo.

Detailed explanation-4: -In plants, fertilization is a process of sexual reproduction, which occurs after pollination and germination. Fertilization can be defined as the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote. It is a physicochemical process which occurs after the pollination of the carpel.

Detailed explanation-5: -Plant fertilization is the union of male and female gametes (reproductive cells) to produce a zygote (fertilized egg).
