  • Define Photosynthesis
    Photosynthesis: the process by which plants manufacture carbohydrates from raw materials (water and CO2) using energy from light.
  • The plant tissue that carries food materials DOWNWARD from the leaves to the rest of the pant is the ______.
    phloem
  • What is responsible for Translocation in plants, the xylem or the phloem?
    the phloem
  • How do you call the vessel that transports water and dissolved minerals and has lignified walls made of cellulose?
    Xylem
  • The 3 limiting factors that affect the rate of TRANSPIRATION are temperature, humidity and light intensity. True or false?
    True
  • The cells made up the stomata is ....
    Guard cell
  • How do water enter the roots from the soil? what is the term for the process?
    Osmosis
  • Name the equation for photosynthesis.
    water + carbon dioxide ---> glucose + oxyigen Where would you write the light and chlorophyll?
  • Movement in the phloem tissue goes in one direction. True or false?
    False
  • "Chlorophyll is a green pigment that traps light. It can be found inside the chloroplasts" True or false?
    True
  • Movement of sucrose and amino acids in phloem; from regions of production (sources) to regions of storage or to regions of utilization in respiration or growth. What term to call that process?
    Translocation
  • How do you call the vessel that transports nutrients?
    Phloem
  • As the amount of carbon dioxide increases, the rate of photosynthesis _____.
    increase

    increase
  • What does the phloem transport
    Sugar/ sucrose/ Photosynthesis product
  • An increase in wind or temperature will ________________ transpiration
    increase
  • Where does sugar transport begin?
    leaves
  • Transpiration is the _______ of water at surfaces of the mesophyll cells followed by loss of water vapour from plant leaves, through _______.
    evaporation - stomata.
  • The image represents xylem and phloem in the different transverse sections of the plant. Can you tell which drawing corresponds to the leaf and which one to the stem?
    Upright: stem, down: leaf
  • Vascular bundles are made up of _______ and _______.
    xylem - phloem
