The upcoming discussion will update you about the differences between Transpiration and Guttation.
Difference # Transpiration:
1. It is the loss of water by a plant in the form of vapours.
2. The transpired water is pure water.
3. Transpiration occurs through the general surface of the leaves and the young stems.
4. It does not leave anything on the surface of the plant.
5. Most of the transpiration occurs during the hotter periods of the day. It is negligible during night.
6. Transpiration occurs through stomata, lenticels and epidermal cells.
7. Stomata can be opened or closed.
8. Transpiration causes the development of a negative pressure in the xylem of the plant.
9. It occurs during dry periods.
10. Transpiration continues even when the plant is under water stress.
11. Excessive transpiration produces wilting.
Difference # Guttation:
1. Guttation is the loss of liquid droplets from the plant.
2. Guttated water is a dilute solution of both inorganic and organic substances.
3. Guttation commonly occurs at the margins and the tips of the leaves.
4. An incrustation of salts is formed on the surface after the guttated liquid evaporates.
5. Guttation mostly occurs during night and early hours of the morning.
6. Guttation occurs only through water pores.
7. The water pore is always kept open.
8. Guttation is produced only when the xylem shows a positive pressure.
9. Guttation takes place during humid periods.
10. It does not occur under conditions of water deficiency.
11. Excessive guttation does not cause loss of turgidity.
