Question

What is the pre fertilization stage of sexual reproduction in plants and what are the major events of this stage?

Answer 1

Main pre-fertilisation stage of sexual reproduction in plants is of gametes. Gametes are the reproductive cells that fuse to form zygote.
Main Pre-fertilization events: These include all preparatory events which occur in the organism before fusion of gametes.
They are gametogenesis and gamete transfer.
During gametogenesis two kinds of specialised cells called gamete (female gamete -ovum /egg and male gamete- antherozoid /sperm) are formed inside gametangium.
Gamete transfer involves transfer of male gamete to near female gamete for fertilization. In plants it is called pollination. The male gametes are mostly small and motile, so that can reach to the female gamete easily. Female gametes are large, non motile and store food to nourish embryo.
