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.
Behavior of plant guard cells: open or closed stomata. On an exam of mine, I had the following question: The interaction between the guard cells and stomata in a plant leaf can be seen in the diagram below. In which scenario could the guard cells and stomata be in situation 2? (A) High humidity (B) High light intensity (C) Low temperatures (D) Nighttime
