TRANSPORT IN PLANT

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: -Water vapour comes out from the plant leaf through the stomatal opening. Through the same stomatal opening, carbon dioxide diffuses into the plant during photosynthesis.

Detailed explanation-2: -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.

Detailed explanation-3: -Water enters and leaves cells through osmosis, the passive diffusion of water across a membrane. In plants, water always moves from an area of higher water potential to an area of lower water potential.

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 is the biological process by which water is lost in the form of water vapour from the aerial parts of the plants.”
