Question

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

Answer 1

The correct option is A

when the root pressure is high and the rate of transpiration is low

Guttation is the loss of water in the form of water droplets from hydathodes (small pores) on the leaf margin of a small herbacious plant. It occurs when root pressure is high and rate of transpiration is low and there is high humidity in the air.
