Classification of Plants
Classification is a method of grouping of things on the basis of common features. It helps in the easy and systematic study of plants and animals as well as in identification of living organisms. Living organisms are first classified into plants and animals. Plants may be classified in several different ways. On the basis of size and shape, plants can be classified as herbs, shrubs and trees. Plants can be grouped as annuals, biennials and perennials depending upon their life span. Perennial plants are further classified into Deciduous Trees and Evergreen Trees. Deciduous trees shed their leaves once in a year, usually before winter while evergreen trees never shed their leaves at one time On the basis of mode of nutrition, plants are classified as autotrophs and heterotrophs. Autotrophs manufacture their own food. Heterotrophs are dependent on others for their food. Heterotrophs can further be segregated as saprotrophs and parasites. Saprophytes feed on dead and decayed plants. Parasites obtain food from host. On the basis of their natural habitat, plants can be categorized as mesophytes, xerophytes and hydrophytes. Mesophytes are the land plants which can survive in neither too dry nor too wet conditions. Xerophytes grow in desert while hydrophytes grow in water.
