Grasses are a family of plants with leaves that usually look like blades. Most of them also have hollow stems and many branching roots. The green grass found in yards, the grasses growing on open land, grains, and bamboos all belong to the grass family. Where Grasses Grow Read Aloud: Rewind (Subscriber Feature) Read Aloud: Play/Stop (Subscriber Feature) Read Aloud: Fast Forward (Subscriber Feature) Grasses grow almost everywhere on Earth because they can survive in many different climates. Large areas of wild grass are called grasslands. The different types of grasslands include prairies, steppes, savannas, and pampas. Physical Features Read Aloud: Rewind (Subscriber Feature) Read Aloud: Play/Stop (Subscriber Feature) Read Aloud: Fast Forward (Subscriber Feature) Some grasses, such as bluegrass, are very short. Others, such as giant bamboos, grow as tall as 100 feet (30 meters). Most grasses are soft and bendable, but bamboos are harder, woody grasses. Grasses have stems with joints. A leaf sprouts from each joint. Except for corn, sorghum, and a few others, grasses have hollow stems. The stems of many grasses grow close to the ground, so mainly the leaves are visible. In tropical regions grass leaves are broad. Desert grasses have spiky leaves that help keep moisture inside. The leaves of some water grasses are waxy. The waxiness protects them from the water. Grasses depend on the wind to scatter their pollen and seeds. Some grass seeds will sprout quickly if they land in the soil. Others need to freeze before sprouting. Grasses may also spread through special underground stems. The stems grow in a horizontal direction, and new sprouts grow up from the stems. Uses Read Aloud: Rewind (Subscriber Feature) Read Aloud: Play/Stop (Subscriber Feature) Read Aloud: Fast Forward (Subscriber Feature) Since ancient times people have eaten the seeds of many grasses. These grasses, called grains or cereals, include corn, barley, millet, oats, rice, rye, sorghum, and wheat. Livestock, or farm animals that are raised by people, also eat grains. Both livestock and wild animals graze on wild grasses. After people take the seeds from cereals, the stalks of the plants are left. When dried, these stalks are called straw. Farmers cover the floors of barns with straw. People in some parts of the world use straw to build roofs. People also weave straw to make furniture, mats, baskets, and hats. People grow grass lawns because grass makes a yard look green and attractive. But grasses are also important to the environment. Grass roots spread in all directions. These roots prevent erosion, or the loss of soil, by holding the soil in place.
