Guttation takes place through

✅ Explanation: Hydathodes are specialized structures, often located at the margins or tips of leaves, that facilitate guttation. They are essentially pores that allow the exudation of water droplets when root pressure is high and transpiration is low (typically at night or in humid conditions).

📌 Other Options Explanations:
-Stomata: These are pores primarily involved in gas exchange (CO2 intake and O2 release) and transpiration (water loss as vapor)
-Lenticels: These are pores found on the bark of woody stems and roots, allowing for gas exchange.
-Trichomes: These are hair-like structures on plant surfaces with various functions, including protection and reducing water loss.

🔑Key Points :
-Guttation is the process of loss of plant sap in the form of droplets from the leaf margins or tips.

✏️It occurs when two of the following conditions are present:
-transpiration is low due to low evaporation rate.
-water absorption is high due to high root pressure.
-Thus, guttation is not observed in tall trees where the force required for guttation will be too high.
-It is usually observed in grasses and mustard plant.
-Guttation takes place through special structures on the leaves called hydathodes.
-Hydathodes are small pores at the tips and margins of the leaf, which are used to remove the surplus xylem sap of the plants.
-The pores of hydathodes remain open at all times.
-The droplets that are exuded contain dissolved substances along with water.
-Guttation is usually observed at midnight or early morning.

• 🛑Additional Information:
-Lenticels – are porous tissues present in the bark of trees and help in gaseous exchange.
-Pneumatophores – are modified aerial roots that are used by roots of mangrove plants for uptake of oxygen.
-Phellogen – is also known as cork cambium that leads to the formation of the periderm in secondary growth of stem and root.
