  • Organelles
    • Nucleus
      • Large organelle surrounded by a nuclear envelope containing many pores. The nucleus contains chromatin and nucleolus
      • Controls Cell's activities and the pores allow substances to move between the nucleus and the cytoplasm. The nucleolus makes ribosomes
    • Lysosome: A round organelle surrounded by membrane, no clear internal structure
      • Contains digestive enzymes, these are kept separate from cytoplasm by surrounding membrane, used to digest invading cells or to break down worn out components of the cell
    • Ribosome
      • Very small organelle, either floats free or attached to RER. Made up of proteins and RNA. Not surrounded by membrane
      • The site where proteins are made
    • Rough endoplasmic reticulum (RER)
      • System of membranes enclosing a fluid-filled space. surface is covered in ribosomes
        • Folds and processes proteins that have been made at the ribosomes
    • Smooth Endoplasmic Reticulum (SER)
      • Similar to RER, but with NO ribosomes
        • Synthesises and processes lipids

    • Vesicle
      • Small fluid-filled sac in the cytoplasm, surrounded by membrane
