Detailed explanation-1: -By the late 1830s, botanist Matthias Schleiden and zoologist Theodor Schwann were studying tissues and proposed the unified cell theory. The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
Detailed explanation-2: -The Core Principles of Physiology The cell theory states that all biological organisms are composed of cells; cells are the unit of life and all life come from preexisting life.
Detailed explanation-3: -The CELL THEORY, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology.
Detailed explanation-4: -The cell theory incorporates three principles: Cells are the most basic building units of life. All living things are composed of cells. New cells are made from preexisting cells, which divide into two.
Detailed explanation-5: -This means that cells form the parts or an organism and carry out all of the an organism’s processes, or functions.
