Organization of cell:

In living organisms, the cells organize in three ways to make the bodies of organisms Cells make unicellular, colonial, and multicellular organizations and the organisms formed through these organizations are unicellular, colonial organisms, and multicellular organisms.

Unicellular organization:

In unicellular organisms, only one cell makes the life of an organism. All the life activities are carried out by the only cell. We are familiar with Amoeba and Euglena etc.

Multicellular organization:

In multicellular organization, cells are organized in the form of tissues, organs, and organ systems. Frog and mustard are familiar examples of multicellular organization.

Colonial type of cellular organization:

In the colonial type of cellular organization, many unicellular organisms live together but do not have any division of labor among them. Each unicellular organism in a colony lives its own life and does not depend on other cells for its vital requirements. Volvox is a green alga found in water that shows colonial organization. Hundreds of Volvox cells make a colony. Sometimes a Volvox colony consists of daughter colonies. Each cell of the colony has two flagella at the anterior end, which are directed toward the surface of the colony. The colony moves in water by the combined action of the flagella of the cells.
