    Translocation
  • The cell membrane of root hair is _____________ permeable in nature
    Semi
  • What does the phloem transport
    Sugar/ sucrose/ Photosynthesis product
  • Name the special cells available in plants for the transport of water and food.
    Xylem and Phloem
  • Vascular bundles are made up of _______ and _______.
    xylem - phloem
  • Transpiration is the _______ of water at surfaces of the mesophyll cells followed by loss of water vapour from plant leaves, through _______.
    evaporation - stomata.
  • What do you call the vessel that transports water and dissolved minerals and has lignified walls made of cellulose?
    Xylem
  • The plant tissue that carries food materials DOWNWARD from the leaves to the rest of the pant is the ______.
    phloem
  • What is Lignin?
    polymers that form key structural materials in the support tissues of most plants.
  • What is responsible for Translocation in plants, the xylem or the phloem?
    the phloem
  • How do water enter the roots from the soil? what is the term for the process?
    Osmosis
  • What do you call the vessel that transports nutrients?
    Phloem
  • What is the function of Xylem fibres?
    To provide mechanical support.
  • Name the 4 types of cells that make up Xylem.
    Vessels, Tracheids, Xylem Parenchyma, Xylem Fibres
  • Movement in the phloem tissue goes in one direction. True or false?
    False
  • The 3 limiting factors that affect the rate of TRANSPIRATION are temperature, humidity and light intensity. True or false?
    True
  • Rate of transpiration decreases with the increase in the humidity. State if it is True or False.
    True
  • An increase in wind or temperature will ________________ transpiration
    Increase
  • Any 2 functions of Xylem
    Food storage, Carrier of water and mineral, Mechanical support.
  • What is the function of stomata?
    Functions as a gate for the entry and exit of the gases and plays an important role in transpiration.
