Cell Structure

• Centrioles


  Structures found in the cytoplasm made of microtubules that produce the spindle fibres during mitosis.
• Bacteria replicate by binary fission.
• Eukaryotic cells contain 80S ribosomes.
• Prokaryotic cells contain 70S ribosomes.
• Cell-surface membrane


  Controls passage of entry of substances into the cell and site of cell communication via receptors
• Large, permanent vacuole


  Maintains cell structure (turgidity) and acts as a temporary energy store
• Cell wall


  Provides support and mechanical strength
