  • Cell Organelles
    • Nucleus
      • Only in eukaryotic cells and can be seen under a light microscope.
    • Rough and Smooth Endoplasmic Reticulum
      • They are flattened membrane sacs called cisternae. The smooth doesn't have ribosomes and they are one continuous memrane.
      • Smooth ER creates the lipids that the cell needs.
      • Rough ER transports proteins made on the ribosomes.
    • Lysosomes
      • Spherical sacs surrounded by a single membrane.
      • Contains enzymes which break down materials eg white blood cells break down invading microorganisms
      • Found only in animal cells but not red blood cells.
    • Mitochondria
      • Double membrane, the inner has folds called cristae. The central part of the mitochondrian is called the matrix.
      • Produce ATP (energy) during respiration. The activities in the cell are powered by the ATP.
    • Golgi apparatus
      • Receives and modifies the proteins then packages them in vesicles so they can be transported.
      • Eukaryotic cells only
    • Chloroplasts
      • Two membranes filled with fluid, inner membrane has thylakoids (a stack is a granum)
      • The site of photosynthesis, carbohydrate molecules are made from CO2 and water.
      • Only found in plant cells.
  • There are nuclear pores on the nuclear envelope and a dense spherical structure called the nucleoulus
    • Nucleus
      • Only in eukaryotic cells and can be seen under a light microscope.
  • It houses the cell's genetic materials, the chromatin has DNA and proteins.
    • Cytoskeleton and centricles

          • The site of photosynthesis, carbohydrate molecules are made from CO2 and water.
          • Only found in plant cells.
      • Cytoskeleton is a web of fibres inside the cytoplasm. There are three types of fibres.
    • The cytoskeleton supports the cell and the centrioles help in the completion of cytokinesis. In animal cells they help with cell division.
      • Cytoskeleton and centricles
        • Cytoskeleton is a web of fibres inside the cytoplasm. There are three types of fibres.
    • Found only in eukaryotic cells and can't be seen under microscopes.
      • Ribosomes
        • They are very small and some are alone, others are bound to the ER. They have no membranes.
        • The site of protein synthesis in the cell. mRNA is used here to assemble proteins from amino acids.
        • In prokaryotic cells they are much smaller but found in all three types of cell.
      • Found in eukaryotic cells only.
        • Large stack of folded membranes. Contains vesicles and has cisternae.
