Excerpt from Elements of ZoologyWe know that a bird eats, moves, and breathes, and that its blood circulates; but plants also eat, respire through their leaves, have a circulation of sap, and some are endowed with locomotive powers. When we descend to the lower forms of animal and vegetable life, the points of similarity become almost identical; the swift-mov ing diatom so resembling some of the lowest animal forms that it is well-nigh impossible to distinguish be tween them. The plants, however, have no nervous sys tem, no special organs Of circulation or digestion that characterize the majority of animal forms, so that an ani mal differs mainly from a plant in possessing, as a rule, a nervous system and special organs of Circulation and digestion.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
