cell structures

• cytoplasm

  • where enzymes and other proteins are made.
  • location of reactions in anaerobic respiration.
• nucleus

  • contains DNA for making enzymes and other proteins used in chemical reactions such as photosynthesis and respiration.
• cell membrane

  • allows gases and water to diffuse freely into and out of the cell.
  • controls the transport of other molecules.
• mitochondria

  • contains enzymes for the reactions in aerobic respiration
• ribosomes

  • where amino acids are joined together to make a protein.
• chloroplast

  • contains the green pigment, chlorophyll, which absorbs light for photosynthesis
  • the enzymes needed for photosynthesis.
• cell wall

  • strengthens the cell and supports the plant.
• vacuole

  • filled with cell sap to help support the cell.
