Question

What is transpiration and where in the leaf does it occur

Answer 1

Answer:

Transpiration is the evaporation of water from plants. It occurs mostly at the leaves while their stomata (small pores on the underside of leaves) are open for the movement of CO2 and O2 during photosynthesis. ... Transpiration also cools plants and enables the mass flow of nutrients and water from the roots to the shoots.
