Transpiration involves the evaporation and diffusion of water vapour.What happens to the water vapour during transpiration?
A
evaporation from mesophyll cells followed by diffusion through stomata
B
diffusion from mesophyll cells followed by evaporation through stomata
C
evaporation from stomata followed by diffusion through mesophyll cells
D
diffusion from stomata followed by evaporation through mesophyll cells
Explanation: 

Detailed explanation-1: -First, the water moves into the mesophyll cells from the top of the xylem vessels. Then the water evaporates out of the cells into the spaces between the cells in the leaf. After this, the water leaves the leaf (and the whole plant) by diffusion through stomata.

Detailed explanation-2: -Plant transpiration is generally an invisible process as the water from the exiting the leaves evaporates quickly. The temperature inside the bag will increase with heating from the sun. However, the water vapor will condense back into water as it comes in contact with the bag’s surface.

Detailed explanation-3: -Stomatal Transpiration It is the evaporation of water from the stomata of the plants. Most of the water from the plants is transpired this way. The water near the surface of the leaves changes into vapour and evaporates when the stomata are open.

Detailed explanation-4: -Because there is a higher concentration of water vapor inside the leaf than outside, the water vapor moves out of the leaf through the stomata by diffusion. This process is known as evaporation.

Detailed explanation-5: -Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves.
