Question:
Differentiate between Apoplast and Symplast pathways of water movement. Which of these would need active transport?
Solution:
1. Apoplast consists of non-living parts of the plant whereas symplast consists of living parts of the plant.
2. Water diffusion in apoplast occurs by passive diffusion whereas in symplast occurs by osmosis
3. Resistance is less to water movement in apoplast whereas in symplast resistance is more to water movement.
Symplast pathway of water movement requires active transport.
