Which one of the following essential elements plays an important role in opening and closing of stomata?
Open in App
Solution
The correct option is B K
According to this theory, the change in the turgor pressure of the guard cells that open and close the stomata results in absorption and loss of K+ ions by guard cells. Opening of stomata in light: Starch in guard cells is metabolized into phosphoenolpyruvate (PEP). Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry.
So, the correct answer is B.
