Differentiate between apoplast and symplast pathways of water movement. Which of these would need active transport?
The apoplast pathway facilitates the movement of water through the root, and this is due to the cortical cells being loosely arranged. The symplast pathway facilitates a very small amount of water transport. The water movement in the apoplast pathway is restricted to the Casparian strip, and thus the symplast pathway is taken instead.
