What is guttation, and how does it differ from transpiration?
Original Khojo Papers practice question — not from a past board paper.
Answer
Guttation is the loss of water as liquid drops from the margins of leaves through special pores called hydathodes, and it happens when root pressure is high and transpiration low, usually at night. Transpiration is the loss of water as vapour, mainly through the stomata, and it takes place chiefly in the day.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Guttation water contains dissolved salts, whereas transpired water is pure.
