allery**Guttation** is:
ALoss of water vapour from stomata
BLoss of water in liquid form through specialised structures called hydathodes (water stomata)
CActive uptake of water at root tips
DPhotosynthetic by-product
Answer & Solution
Correct answer: B. Loss of water in liquid form through specialised structures called hydathodes (water stomata)
**Guttation:** liquid water exudes from hydathodes (modified stomata) at leaf margins/tips, typically at night when root pressure is high and transpiration low.
Often seen as morning droplets on grass.
