Explanation:
Detailed explanation-1: -If guard cells in a plant were deficient in K+, which of the following would be most likely to occur? Photosynthesis would decrease. What tissue is indicated by label line 1?
Detailed explanation-2: -With the entry of several K+ ions and chloride ions, the water potential of guard cells increases.
Detailed explanation-3: -An increase in potassium(K) ion makes the guard cells hypertonic so that more water can enter inside the cells. During this, the stomatal pore is opened. Closing is just an opposite phenomenon of opening as in closing the water is removed from the guard cells and they become flaccid.
