Answer 1

The correct option is A

turgor pressure

The loss of water from the living tissue of aerial parts of plant in the form of water vapour is called transpiration. More than 95% of total loss of water takes place through stomata. Opening and closing of stomata occurs due to turgor change in guard cells. Therefore, transpiration is manifestation of turgor pressure.
