Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Water vapour moves out of the plant leaf by the process of
A
osmosis
B
evaporation
C
active transport
D
diffusion
Explanation: 

Detailed explanation-1: -Transpiration-It is the process of diffusion of a water droplet through the stomatal opening. It is simply the loss of water through leaflets. It occurs mostly at night or early morning.

Detailed explanation-2: -The water eventually is released to the atmosphere as vapor via the plant’s stomata-tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.

Detailed explanation-3: -Transpiration is the evaporation of water from plants. It occurs chiefly at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis.
