प्रश्न
Differentiate between Apoplast and Symplast pathways of water movement. Which of these would need active transport?
उत्तर
| Apoplast Pathway | Symplast Pathway |
| (i) The intercellular gaps and cell walls are the only places where water can travel apoplastically. | (i) The symplastic movement of water occurs through the cells -their cytoplasm and intercellular movement are through the plasmodesmata. |
| (ii) The apoplast pathway does not provide any barrier to water movement. | (ii) The symplast pathway provides a little barrier to water movement. |
| (iii) It consists of the nonliving parts of the plant body. | (iii) It consists of living parts of the plant body. |
| (iv) Movement of water in this pathway is faster. | (iv) Movement of water in this pathway is relatively slower. |
Active transport is not required by any of these pathways.
