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.
This region of the mesophyll cells, then, is sort of, but not exactly, like our lungs and is a vital part of the photosynthesis activities of the leaf. The combination of guard cells and stoma is called the stomate. The stoma is just what they call the opening that connects the outside to the inside.
