Cells

• Eukaryotic cell


  Cell which has a nucleus and other structures surrounded by membranes
• Cell membrane


  Selectively permeable membrane surrounding the cell and controlling the entry and exit of materials
• Animal cell


  • Made up of eukaryotic cells
  • Cells have a nucleus and other membrane-bound structures in the cytoplasm
• Cytoplasm


  Jelly-like material that contains dissolved nutrients and salts, and structures called organelles. Where many chemical reactions happen.
• Nucleus


  Contains genetic material, including DNA, which controls the cell's activities
• Cell membrane


  Permeable to some substances but not others, controls movement of substances in and out of the cell
• Mitochondria


  Organelles that contain the enzymes for respiration, where most energy is released in respiration
• Ribosomes


  Tiny structures where protein synthesis occurs
• Most cells are specialised and adapted for their function. Animals and plants consist of many different types of cells working together.
