Question

How is root pressure linked to guttation?

Answer 1

Root pressure:

1. Different ions from the soil are actively carried into the vascular tissues of roots.
2. The pressure in the xylem rises as water follows the potential gradient.
3. Root pressure is created as a result of this positive pressure.
4. Its effects are seen early in the morning and late at night, when evaporation is minimal and surplus water collects in droplets at the leaf tips of various herbaceous plants.
5. Guttation is the loss of water (in the liquid phase) from the surface.
6. As a result, root pressure causes a positive pressure to be formed in the xylem, causing the guttation process to occur.
