A cell type is a distinct morphological or functional form of cell. When a cell switches state from one cell type to another, it undergoes cellular differentiation. Three Domains of life: Eukaryota, bacteria and archaea [1] Eukaryotes: animals, humans, plants and , also algae, and protozoa. Prokaryotes: bacteria and archaea (Special kind of prokaryotes).
Animals
Humans
Different cell types react differently to external stimuli. For instance, the function of PKA differs from cell type to cell type. Calcium, too, has specific cell type actions in humans.
