Question

Describe the various steps leading to the formation of seeds in plants

Answer 1

First is pollination followed by germination of pollen grain on the stigma and fertilisation of one of the male nuclie (developes into an embryo) and egg and other male nuclie and polar nuclie (developes into an endosperm). Outer wall of the ovule like inner and outer integuments form the seed coat enclosing endosperm and embryo inside it.
