Animal / Plant cells

• Cytoplasm

  A jelly-like material that contains dissolved nutrients and salts and structures called organelles. It is where many of the chemical reactions happen.
• Nucleus

  Contains genetic material, including DNA, which controls the cell's activities.
• Cell membrane

  Its structure is permeable to some substances but not to others. It therefore controls the movement of substances in and out of the cell.
• Mitochondria

  Organelles that contain the enzymes for respiration, and where most energy is released in respiration.
• Ribosomes

  Tiny structures where protein synthesis occurs.
• Electron vs Light microscope

  Animal cell

  
• Chloroplast

  Organelles that contains the green pigment: chlorophyll, which absorbs light energy for photosynthesis. Contains the enzymes needed for photosynthesis.
• Cell wall

  Made from cellulose fibres and strengthens the cell, defines its shape, and supports the plant
• Permanent vacuole

  Filled with cell sap to help keep the cell turgid (swollen)
• Electron vs Light microscope


  Plant cell

  
• Eukaryotic cell

  • A cell that has a nucleus
  • bigger of the 2

  animal and plant cells
• prokaryotic cells

  • Does not have a nucleus - (the DNA is free in the cytoplasm)
  • The smaller of the 2
  • Bacteria cells
• What are stomata?


  Pores in the epidermis of leaves that control the rate of gas exchange
• Carbon dioxide diffuses into the leaf through the


  Stomata
