Question

o Explain the phenomenon of double
fertilization and its significance
in angiosperm life cycle.​

Answer 1

Answer:

Double fertilization provides stimulus to the plant as the ovary develops into a fruit. Due to the fusion of male and female haploid gametes, a diploid zygote is formed. The zygote develops into an embryo, giving rise to a new plant.

Answer 2

One of the male gametes fertilizes the egg resulting in the formation of a zygote and the other unites with 2 polar nuclei for the formation of an endosperm. Double fertilization provides stimulus to the plant resulting in the ovarian development to fruits and development of ovules into the seed.
