Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Water ____ from the plant during transpiration
A
transpires
B
evaporates
C
respiration
Explanation: 

Detailed explanation-1: -Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration. Water also evaporates directly into the atmosphere from soil in the vicinity of the plant.

Detailed explanation-2: -Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves.

Detailed explanation-3: -Transpiration is just a subset of the evaporation process, and it’s the water that is inside plants, and then when that evaporates and moves into the atmosphere, that process is called transpiration.

Detailed explanation-4: -Stomata are open to let carbon dioxide in for photosynthesis; however, this also causes the water in the mesophyll tissue in leaves to evaporate if the air outside is drier due to factors like high temperature.

Detailed explanation-5: -Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.
