- - - - Tissue
        
        Vascular tissue = xylem and phloem
        
        Ground tissue = palisade and mesophyll cells.
        
        Dermal tissue = epidermis
  - - - Tissue
        
        muscular tissue = wall of the heart is cardiac muscle
        
        epithelial tissue = enclosed in membrane called pericardium
        
        connective tissue = Blood and vessels
        
        nervous tissue = heart is controlled
- - - - contains cells in a matrix and is produced by connective cells.
      - adipose tissue (stores fat), cartilage, bone and blood
    - - composed of nerve cells, adapted to carry impulses to and from the brain.
      - Example = neurones
  - - - Location = Outer layer of stem, leaves and roots.
      - Appearance = rectangular cells, thickened cell wall, lots of chloroplasts.
      - Function = protect the plant, cuticle present - prevents water loss
    - - Location = Between dermal and vascular tissue
      - Appearance = rectangular cells, lots of chloroplasts.
      - Function = lots of chloroplasts - photosynthesis , spongy mesophyll - store gases
- - - - They grow to form a callus.
      - Change the conditions so the callus can continue to grow.
      - Grow on a suitable medium.
      - In time a young plant will form.
      - Cut plant into small pieces (e.g. carrot).
    - - Can produce lots of plants.
      - Plants are genetically identical.
      - Can be used to save threatened species.
  - - - no need for removal of skin from other parts of the body.
      - new skin is identical to the patents skin and is not as likely to be rejected.
