Detailed explanation-1: -In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
Detailed explanation-2: -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. The second part states that cells are the basic units of life.
Detailed explanation-3: -This means that cells form the parts or an organism and carry out all of the an organism’s processes, or functions.
Detailed explanation-4: -1) All organisms are made of cells. 2) All existing cells are produced by other living cells. 2) All existing cells are produced by other living cells. 3) The cell is the most basic unit of life.
Detailed explanation-5: -Virchow’s theory stated that just as animals are unable to arise without previously existing animals, cells are unable to arise without previously existing cells. The idea that new cells arose from pre-existing cells in both diseased and healthy tissue was not original.
