1. Which of the following is not correct?
(c). Virchow explained that cells are formed from pre-existing cells.
Correct statement. Earlier cell theory as proposed by Schleiden and Schwann stated that all organisms are made up of cells. The cells are the basic structural and functional units of life. However, this theory did not explain the origin of cells. Later on, Virchow suggested that all cells arise from pre-existing cells.
