प्रश्न
Differentiate between Apoplast and Symplast pathways of movement of water in plants
उत्तर
| Apoplast pathway | Symplast pathway | ||
| 1 | The apoplast pathway involves the movement of water through the adjacent cell walls of the epidermis and cortex. The movement of water is restricted at the casparian strips of the root endodermis | 1 | The symplast pathway involves the movement of water through the interconnected protoplasts of the epidermis, cortex, endodermis, and root pericycle |
| 2 | It is a faster process of water movement and water moves through mass flow. | 2 | It is a slower process of water movement. |
