Plants are one of the major forms of life and contain familiar organisms such as trees, shrubs, vines, grasses, ferns, and green algae, and lichens. Plants can be divided into seed plants, algae, mosses, ferns, etc. It is estimated that there are about 450,000 species in existence.
Green plants get most of their energy from sunlight through photosynthesis, and temperature, humidity, light, and freshwater are the basic needs of plants for survival. Angiosperms have six major organs: roots, stems, leaves, flowers, fruits, and seeds. Green plants have the ability to photosynthesize – with the help of light energy and chlorophyll and catalyzed by enzymes – using water, inorganic salts, and carbon dioxide for photosynthesis, releasing oxygen and producing organic matter such as glucose for use by the plant body.
