Answer 1

-An egg being fertilized by a sperm and developing into a zygote

-A child growing

-A pollen grain landing on a plant ovule that will develop into a seed

Answer 2

Ans.

Cell division or cell reproduction is a process that involves formation of new daughter cells from a single parent cell. Cell division is important for the growth and development, reproduction, and healing of wounds or damaged skin.

The somatic cells or body cells divide continuously to form daughter cells for growth and development of organism. The bacterial cells reproduce by binary fission to form new daughter cells. The cells of damaged area also show division to make new cells that heal the wound or replace the damaged ones.

Thus, the correct options are 'a child growing, a bacterial cell reproducing, and a burned area of skin healing.'
