Closing them prevent reduces water loss, but also limits the diffusion of carbon dioxide and oxygen in and out of the leaf. Note that there are approximately the same number of stomata on either side of the leaf, that the vascular bundles are all facing you in cross section (because they run parallel to each other), and that the mesophyll is not divided into two distinct types. is a genus of flowering plants consisting of two or three very similar species of grasses.The common names for these grasses include marram grass, bent grass, and beachgrass.

American beach grass is a dominant species of sandy ocean and lake beaches and coastal dunes.
The inner (adaxial) surface absorbs water and expands (the "hinge cells" help it); and the inner-face become open. Beauv.)
