Excerpt from Animal Forms: A Text-Book of Zoology In the oak-tree, for example, the roots reaching down into the earth, with the branches and leaves spreading out into the air and sunlight, are admirably fitted for taking up the food, which consists of very simple materials, less com plex than those forming the diet of an animal. This permits a continuous existence in one place, and accord ingly we note the entire absence of locomotion and the or gans controlling it, which form so conspicuous a part of the body of an animal. Also in the production of flowers and seeds, and in the growth of the seed into the tree, we detect many characteristics peculiar to plants.
