      • Nucleus: contains genetic material that controls the activities of the cell.  Cytoplasm: a gel like substance where most of the chemical reactions take place- containing enzymes that control these reactions. Mitochondria: where most of the reactions for respiration take place.. releasing energy.     Cell membrane: holds the cell together and controls what goes in and out.  Ribosomes:  these are where proteins are made in the cell.       Chloroplasts:these are where photosynthesis occurs, which makes food for the plant. They contain chlorophyll, which absorbs the light energy needed.  Permanent vacuole: contains cell sap, a weak solution of sugar and salts.
