5. Differentiate between the following:
(e) Apoplast and Symplast pathways of movement of water in plants.
Apoplast pathway | Symplast pathway |
It consists of nonliving parts of the plant body such as the cell walls and intercellular spaces. |
It consists of living parts of the plant body such as protoplast connected to plasmodesmata.
|
There is little resistance in the movement of water |
Some resistance occurs in the movement of water. |
The metabolic state of the root does not affect the apoplast pathway. |
The metabolic state of the root directly affects the symplast pathway. |
