The terms in the table by defining them.

Introduction:

A cell is the structural, functional, and biological unit of all living organisms. It is smallest unit for life. A cell can be prokaryotic or eukaryotic. Eukaryotic cells contain membrane bound cell organelles, that help in functioning of cellular machinery by carrying out biochemical reactions.

Explanation of Solution

It can be seen in mammals.	External fertilization The fertilization of egg cell and a sperm cell outside the body of female is termed as external fertilization. It can be seen in many amphibians and fish.
Blastula It is the hollow sphere of cells that is produced during embryo development.	Gastrula Gastrula is stage in embryo development just after blastula stage. It contains three layer of cells.
