Answer:
If the structure marked X is blocked, then the processes, Transpiration, Photosynthesis, Respiration will not occur
Explanation:
The structure marked X in the diagram is stomata or stomatal pore or stomatal opening. Stomata are the pores that facilitate gaseous exchange and transpiration in leaves. When these spores get blocked, water vapor cannot escape that is transpiration will not occur. Transpiration is the process of exhalation of water as vapors through the stomata. Also, the exchange of gaseous will get interrupted, which will lead to a decrease in the rate of photosynthesis and respiration. Carbon dioxide and oxygen, which are essential for photosynthesis and respiration, respectively, are taken from the atmosphere through these stomata.
If the structure marked X in the diagram given
below is blocked, then Transpiration, photosynthesis and respiration will not occur.
What are stomata?
- Stomata are gas exchange openings on the leaves of plants. Guard cells surround stomata and control their opening.
Function of stomata
- When the guard cell is fully inflated, pressure builds up, forming a pore that allows water to escape and gas to exchange. This way it helps in both transpiration and respiration.
- Carbon dioxide must travel from the air into the leaf when a plant performs photosynthesis. This is accomplished by diffusing through microscopic pores known as stomata.
Therefore, transpiration, photosynthesis and respiration will not occur if stomata are blocked.
