Question : Loss of water in plants in the form of liquid is known as:
Option 1: transpiration
Option 2: osmosis
Option 3: guttation
Option 4: imbibition
Correct Answer: guttation
Solution : The correct option is guttation .
Guttation is the process by which plants pass liquid water from their leaf tips due to root pressure, which occurs when water absorption exceeds transpiration, which occurs frequently in the morning or humid weather. Guttation occurs via specialised structures known as hydathodes, which are tiny apertures on the leaf edges. Guttation differs from dew production in that it occurs when moisture in the air condenses on the surfaces of plants or other things when temperatures fall.
