If you were asked to name the parts of a plant, you probably would list roots, stems, leaves, and perhaps flowers. You may also know that many plants grow from seeds. But did you know that some simple plants have none of these parts? Nonvascular plants, the bryophytes, don?t have roots, stems, or leaves. They do have rootlike fiber, stalks that look like stems, and leaflike green growths. Instead of growing from seeds, bryophytes grow from spores. The nonvascular plants include mosses and liverworts. A moss is a simple rootless plant with leaflike growths in a spiral around a stalk. Moss plants are held in place by rootlike filaments or threads made up only a few long cells called rhizoids. One type of liverwort is a simple, rootless plant that has a flattened, leaflike body. Liverworts get their name because, to some people, they look like a liver. The ending, -wort, means ?herb,? so the word liverwort means ?herb for the liver.? In liverworts rhizoid is made up of just one cell. Both mosses and liverworts grow in damp areas and range in size from 2 to 5 centimeters in height. Of approximately 20 000 species of nonvascular plants, most are classified as mosses. H
