Grass is a very common plant consisting of large numbers of thin, spiky, green leaves that cover the surface of the ground. Small things stirred in the grass around the tent. The lawn contained a mixture of grasses.

Grasses are usually herbaceous which indicate that they produce a seed, do not develop woody tissue, and die down at the end of a growing season. They are monocotyledonous which means one leaf sprouts from the seed, and often have jointed, slender, sheathed leaves. A cotyledon is the first leaf to emerge from a seed.

This plant also has important ecological functions: it protects against soil erosion, it absorbs water, it purifies the air we breathe and so on. Every variety of grass has its own special properties. The grass family, or Graminae, has about 8,000 varieties.
