The process of guttation takes place
A. when the root pressure is high and the rate of transpiration is low.
B. when the root pressure is low and the rate of transpiration is high
C. when the root pressure equals the rate of transpiration
D. when the root pressure as well as rate of transpiration are high.
Guttation is the loss of water in form of water droplets via structures called hydathodes. In the evening or early morning, the rate of absorption of water exceed the rate of transpiration due to which a lot of water accumulates which if not exudated out might be of damage to the plant. So plants opt for guttation.

Define Uniport, Symport and Antiport. Do they require energy?
I) Uniport: When a single substance moves in a single direction across a cell membrane, it is called uniport.
II) Antiport: When two substances move in the opposite direction across a cell membrane, it is called antiport.
III) Symport: When two substances move in the same direction across a cell membrane, it is called symport.
