The guard cells, unlike the rest of the epidermis, contain chlorophyll. They are so constructed that as the quantity of water the}^ contain varies tlie slit between them is either opened wider, or narrowed,—or, it may be, quite closed. The guard cells are closed together when flaccid on account of the wilting of the leaf. Stomates arc found on most of tlie green surfaces of the plant, but most al^undantly on the leaf. Here tliey arc generally more numerous on the under side. 529. Trichomes are outgrowths of the epidermis, consisting in the sim- plest cases of single cells, but in many 381.
