Grasses grow from the groundlevel up. Roots supply nutrients, and leaves supply ability to collect energy, carbon dioxide and water from the environment. Grasses have a tiny stem from which the leaves emerge, and a low growth-point called an apical meristem. This apical meristem or growth point is where each individual leaf originates and grows from, and reaches up to the sun. Some grasses emerge as folded leaves like Orchard grass; others are curled up and uncurl as they lengthn, like brome grass does. Because grasses have such a low growth point is the reason why they are able to not be killed when you cut your lawn. Depending on how far the leaves have progressed, some of the older leaves that are cut will die off only to be replaced by newer ones. Other newer leaves that are cut are still young enough to continue to grow.
