Detailed explanation-1: -Cell theory has 3 basic points: All living things are made of one or more cells. The cell is the smallest living thing that can perform all the functions of life. All cells must come from pre-existing cells through cellular division.
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.
Detailed explanation-3: -The classical cell theory was proposed by Theodor Schwann in 1839. There are three parts to this theory. The first part states that all organisms are made of cells.
Detailed explanation-4: -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.
