  • Plants Cells
    • Nucleus
      • contains chromosomes
        • made of DNA & proteins
        • contains genetic information
    • Cytoplasm
      • takes up space not occupied by nucleus
      • includes ions, enzymes, food molecules & organelles
      • Cytosol
        • semi-fluid substance in which organelles are suspended
        • synthesis of proteins, fats & initial steps in release of energy from sugars
      • Cytoskeleton
        • gives cell it's shape & internal organisation
        • consists of network of filaments & tubules
        • cell movement & division
    • Vacuoles
      • filled with ions
      • solution inside cells
      • storage, waste disposal & growth
    • Mitrochondria
      • energy transformers
      • chemical energy from glucose transferred to useable from called adenosine tri-phosphate (ATP)
    • Ribosomes
      • manufacture proteins
      • attached to endoplasmic reticulum
        • network of membranes
        • continuous with outer membrane of nucleus
        • rough side
          • involved in synthesis of lipids & carbohydrates
          • no ribosomes
          • not involved in protein synthesis
        • smooth side
          • ribosomes attached
          • involved in protein synthesis
    • Golgi Apparatus
      • stores, modifies & packages proteins & adds carbohydrates to them to ensure they get to the correct destination
      • processing station
    • Chloroplasts
      • contains green pigment -> chlorofil
      • only found in photosynthetic cells taking light energy, forming ATP & synthesising organic compounds from simple raw materials
