(a) The guard cells are bean-shaped which are found in dicot plants.
(b) The guards cells in figure (i) are turgid as, they pull the inner wall of the cell outside thus, they have more water. (ii) cells are flacid, this condition results when cells lose water and close stomatal pore.
(c) The ions when move from neighbouring cells to guards cells, lowering their water potential as a result the water moves inside making them turgid and thus opening stomata.

I. Carrier proteins are needed for both facilitated diffusion and active transport and are sensitive to inhibitors that react with protein side chains.
II. Different types of proteins present in the membrane play a major role in both active as well as passive transport.
III. The carrier proteins needed by facilitated and active transport are specific.
IV. There is no need of energy to pump molecules against a concentration in active transport.
V. Transport rate reaches a saturation point, when all the active proteins are used.
