The first one has been done for you. Structure Function nucleus Controls what goes in and out of the cell. cytoplasm Where all the activity of the cell happens. cell membrane Controls the activities of the cell. mitochondria Releases energy for the cell through respiration. 2 Now draw lines to match plant cell structures and functions.
