Verified by Toppr

Robert Brown discovered the cell is false because cells were first discovered by Robert Hooke.
Mathias Schleiden, Theodar Schwann, and Rudolf Virchow formulated the cell theory, according to which all living organisms are composed of cells.
Much of the work of Rudolf Virchow was in proving that cells arise from preexisting cells.
Organisms consisting of a single cell carry out all functions of life by means of that single cell.
So, the correct answer is 'Robert Brown discovered the cell'.
