Detailed explanation-1: -The three principles of the cell theory are: Every living organism is made up of one or more cells and products of cells. The smallest living organisms are single cells that are unicellular and cells are the functional units of multicellular organisms. All 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.

Detailed explanation-5: -It states that: All living organisms are made up of cells. Cells are the smallest units in a living organism that can perform all the functions of life. Rudolf Virchow in 1858 said “Omnis cellula-e-cellula", which means that all cells arise from the pre-existing cells only.
