Question

Write a note on:
1. Fertilization in plants.
2. Triple fusion
3. Double fertilization​

Answer 1

Explanation:

This pollen tube then penetrates into one of the synergids, post which two male gametes are released.

One of the two male gametes fuses with the nucleus of the egg cell to produce the zygote, this process is called syngamy

Answer 2

Answer:

Plant Fertilization: the process of fusion of the female gamete, the ovum or egg and the male gamete produced in the pollen tube by the pollen grain. ... The process of fertilization in plants occurs when gametes in haploid conditions meet to create a zygote which is diploid

Triple fusion is defined as fusion taking place between two polar nuclei and sperm nucleus. This happens during double fertilization in a seed plant, and therefore gives origin to a triploid nucleus known as the Primary Endosperm Nucleus(PEN). The PEN later evolves into an endosperm

Double fertilization is a complex fertilization mechanism of flowering plants (angiosperms). This process involves the joining of a female gametophyte (megagametophyte, also called the embryo sac) with two male gametes (sperm).
