NEET BIOLOGY

Detailed explanation-1: -The correct answer is option 2. Concept: The evaporative loss of water through the leaf surface is called transpiration.

Detailed explanation-2: -Transpiration is the process by which plants get rid of excess water through the stomata. The excess water is lost in the form of vapours by transpiration.

Detailed explanation-3: -Guttation is the loss of water in solution form through hydathodes. It occurs under the influence of root pressure.

Detailed explanation-4: -Guttation is the process of secretion of water droplets from the pores of some vascular plants like grass. Guttation is often confused with dew droplets that condense from the atmosphere onto the plant’s surface.

Detailed explanation-5: -The process of loss of water in the form of liquid drops from the edges of leaves or the tips of veins through hydathodes is known as guttation. This process usually happens in herbaceous plants when the humidity is and the root pressure is high and the rate of transpiration is low.
