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.
Phloem tissue is surrounded by strong cells called fibers, which are a type of sclerenchyma, and parenchyma cells that form the cortex. Outside the phloem ring is the bark, a ring of boxy, waterproof cells that help protect the stem.
