Text Solution

Verified by Experts

All living organisms are made up of cells and product of cells. Cell is the basic structural and functional unit of living organism. Each cell have different organelles and perform different functions.
1) Cells obey laws of energetics i.e., they transform energy.
2) Cells highly structured with emergent properties.
3) Cells have an evolutionary origin.
4) Cells metabolize means possess metabolic pathways, process nutrients, self adjust to environment.
5) Cells self replicate - nucleic acids, ribosomes.
6) Cells osmoregulation - vacuoles, vesicles.
7) Cells communicate - Glycoproteins.
8) Cells shows animation Cyclosis.
9) Cell grow, divide and differentiate.
10) Cells die.
