Answer 1

The correct option is B Water is lost through hydathodes.

Transpiration is defined as the loss of water in the form of vapour from the aerial parts of the plant. Transpiration occurs through stomata, cuticles and lenticels. This process occurs during the day in the presence of sunlight. It helps in temperature regulation in plants and upward movement of water and minerals in plants.
Hydathodes are specialised pores which are responsible for guttation.
