Question
Transpiration is the of water from the surfaces of mesophyll cells into the air spaces, followed by the of water vapour through stomata.
Solution
Transpiration is the evaporation of water from the surfaces of mesophyll cells into the air spaces, followed by the diffusion of water vapour through stomata.
Here's the step-by-step process:
-
Water is absorbed by the roots from the soil. This is driven by a process called osmosis, where water moves from an area of high concentration (the soil) to an area of low concentration (the root cells).
-
The water then travels up the plant through a system of tubes called the xylem. This movement is driven by a process called capillary action, which is the ability of a liquid to flow in narrow spaces without the assistance of, and in opposition to, external forces like gravity.
-
The water reaches the leaves of the plant, where it is used in photosynthesis. Photosynthesis is the process by which plants convert light energy, usually from the sun, into chemical energy that can be later released to fuel the plant's activities.
-
Any excess water in the leaves is evaporated from the surfaces of mesophyll cells (specialized cells in the leaves) into the air spaces within the leaf. This process is known as transpiration.
-
Finally, the water vapour exits the leaf through tiny openings called stomata. This is a process of diffusion, where the water vapour moves from an area of high concentration (inside the leaf) to an area of low concentration (the outside air).
