Cellular theory, a theory which derives all the vegetable and animal tissues from the union and metamorphosis of primitive embryonic cells.—Cellular tissue (Organic Structures), a tissue composed of an indefinite number of minute cells communicating with each other. That in animal bodies unites all parts of the body, determines their shape, and facilitates the motion of parts on each other. That of plants is the tissue made up of cells, which covers or composes plants, in distinction from the vascular tissue. The white fibrous and areolar tissues are also called cellular tissue by some authors, although they are composed mainly of fibers. Carpenter.
