  • B2 Organisation
    • plant tissues
      • specialised cells in multi-cellular plants are organised into tissues & organs.
      • epidermal tissues cover the surfaces and protect them.
      • palisade mesophyll tissue contains lots of chloroplasts
      • spongy mesophyll tissue contains some chloroplasts and has big air spaces & a large surface area to make diffusion of gases easier.
      • xylem and phloem transport tissues in plants
    • plant organs
      • each organ carries out their own particular function.
      • in each plant organ there are collections of different tissues working together to perform specific functions.
      • in the body of a plant, specialised tissues such as palisade, spongy mesophyll, xylem & phloem are arranged to form organs.
    • plant organ systems
      • the whole body of a plant-roots, leaves and stem form an organ system
      • plants have tow separate transport systems to move substances around the whole plant.
      • the organ system transports substances around the plant.
    • xylem-moving water & mineral ions
      • its the other transport tissue in a plant.
      • it carries water and mineral ions from the soil around the plant.
      • mature xylem cells are dead.
  • phloem (moves food)
    • it transports the sugars made during photosynthesis.
    • the movement of dissolved sugars from the leaves to the rest of the plant is called translocation.
    • the dissolved sugars are needed for making new plant cells.
    • phloem cells are alive.
