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.
Unformatted text preview: Turgor pressure in guard cells causes stomata to open and close The two sausage-shaped guard cells on each side of a stoma stand out from other epidermal cells not only because of their shape, but also because they are the only epidermal cells containing chloroplasts.
