- - - - pinocytosis
        
        unselective way to sample extracellular fluid
      - phagocytosis
        
        cell engulfs a large particle
      - receptor-mediated endocytosis
        
        substances bind to specific receptors on the cell membrane for transport into the cell
    - - mechanism by which large particles and macromolecules enter the cell
- - - - Endoplasmic reticulum
        
        rough ER
        
        produces proteins
        
        smooth ER
        
        metabolizes lipids and stores calcium
      - Golgi apparatus
        
        packages proteins for use in or out of the cell
      - Lysosomes
        
        break down used proteins and other cellular debris
      - Mitochondria
        
        makes energy
      - Peroxisomes
        
        neutralize and remove toxic substances
      - Ribosomes
        
        produces proteins
    - - dissolved solutes
    - - stored nutrients, pigment granules
- - - - site of ribosome subunit manufacture
    - - DNA molecule plus proteins
    - - regulates passage of substances to and from nucleus
      - separates nucleoplasm from cytoplasm
- - - - cells are metabolically active, make proteins rapidly, grow vigorously
    - - DNA replicates itself
    - - enzymes needed for cell division are synthesized
  - - - division of the nucleus
    - - division of the entire cell into two cells
