2. What are companion cells?

  • Living cells found in phloem that support sieve tube elements by carrying out the living functions for them e.g. providing energy
  • Dead cells that assist sieve tube elements by controlling what they do.
  • Living cells that connect phloem tissue together.

3. What factors affect transpiration rate?

  • Temperature only
  • Light Intensity, Temperature, Humidity, Wind
  • Light Intensity. Humidity, Wet Soil
  • Light Intensity, Wind, Mineral Concentration

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

  • Symplastic Pathway
  • Phloem Tissue
  • Transpiration
  • Xylem Tissue

5. What evidence is there for mass flow?

  • If a ring of bark is removed from a woody stem a bulge forms above the ring because the sugars can't move past the area where the bark has been removed. This is evidence that there is a downward flow of sugars.
  • If a ring of bark is removed from a woody stem a bulge forms below the ring because sugars can't move past. This is evidence that there is a upward flow of sugars.
