Plant transport system

    Cards (14)

    • Root cap is a layer of cells that protects the root as it grows through the ground
    • Epidermis is a layer of cells that covers the rest of the root
    • Root hair provides anchorage to the plant and takes in water from the soil
    • Water and mineral ions (salt) are absorbed by root hairs.
    • Cytoplasm inside of root hair cell contains lots of dissolved molecules including sugars and salt
    • Osmosis is the process by which the roots absorb water
    • Water moves by osmosis
    • Minerals move by active transport
    • Active transport is a process by which the roots absorb mineral ions
    • Xylem transports water, minerals and organic compounds such as amino acids and sucrose
    • Xylem is a type of vascular tissue that transports water and dissolved minerals from the soil by the roots to the rest of the plant
    • Xylem vessels are long, thin, hollow tubes made up of dead cells
    • Phloem, also called bast, transports assimilate (substances made by the plant) from the source
    • Phloem carry sugars (in sap) from leaves to the rest of the plant
