Detailed explanation-1: -The three tenets of the cell theory are: All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.
Detailed explanation-2: -○ The Cell theory has three principles. 1) All organisms are made of cells. 2) All existing cells are produced by other living cells. 3) The cell is the most basic unit of life.
