Other questions in this quiz

2. What is the mass flow hypothesis?

  • The theory that plants transport all substances in one tube and not xylem and phloem.
  • The best supported theory for how solutes are transported from the source to the sink by translocation.
  • The theory that all substances move in coordination with gravity.

3. What is the vacuolar pathway?

  • Movement of water through the vacuole.
  • Movement of water through cell walls, allowing mineral ions and salts to be carried with the water.
  • Movement of water through the cytoplasm through the plasma membrane. The cytoplasm of cells is connected through plasmodesmata.

4. What transports organic substances up and down the plant/

  • Phloem Tissue
  • Xylem Tissue
  • Transpiration
  • Symplastic Pathway

5. What is the SINK in transportation of solutes?

  • The removal of ions from a plant.
  • The site where assimilates (solutes) are used up. e.g. roots
  • The uptake of ions in the roots.
  • The site of production of assimilates (solutes). e.g. leaves
