A tissue consists of one or more cell types. Cells are grouped in tissues and several tissues make up an organ. The ability of plants to grow and develop depends on the ability of individual cells to divide, differentiate and to carry out their intended functions. A cell is the fundamental unit of life. Life does not exist in units smaller than cells.
Cells arise only from the division of of preexisting cells.
