Cell is the fundamental structural and functional unit of all living organisms because:

(1) Anything less than a complete structure of a cell does not ensure independant living.

(2) The metabolic reactions can only occur inside a living cell.

(3) Nucleic acids present in the cells ensure living state.

(4) The membrane bound organelles cause differentiation for proper functioning.

Who concluded, based on his studies on plant tissues, that the presence of cell wall is a unique character of plant cells ?

(1) Mathias Schleiden

(2) Theodore Schwann

(3) Rudolph Virchow

(4) Robert Hooke

Mesosomes in prokaryotes do not help in:
