Calculation of molar mass of glucose (C6H12O6) The molar mass of glucose can be calculated from the molar masses of individual atoms present in it. From the molecular formula, C6H12O6, one can find there are 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms in one molecule of glucose.
Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata.
Now with the GUARD cells the plants hormones can send signals to the guard cells which can help the guard cells figure out whether or not it needs to open or close the stomata. And if the plant is losing water too quickly, the guard cells may close the stomata to help prevent it from happening! :) Comments. Report.
