cell contains hereditary information (DNA + RNA) and passed on to new cells during cell division

17
Q

Modern Cell Theory 2

A

all cells are basically same in chemical activity

18
Q

Modern Cell Theory 3

A

all basic chemical and physiological functions are carried out inside the cell

19
Q

Modern Cell Theory 4

A

cell activity depends on the activities of subcellular structure (cells are inter reliant or all must function)
