Uni-Multi cellular cells

UNICELLULAR
A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, in contrast to a multicellular organism that consists of multiple cells. Historically simple single celled organisms have sometimes been referred to asmonads.

MULTICELLULAR

Multicellular organisms are organisms that consist of more than one cell, in contrast tosingle-celled organisms. To form a multicellular organism, these cells need to identify andattach to the other cells.

Only a dozen or so species of life that can be seen with the naked eye are unicellular. The rest of the nearly two million visible species are multicellular. In particular all but one or two species of the million and a half animals are multicellular, as well as many plants and fungi.
