Thus the living cells are the plant's stomach, its lungs, and its heart, in so far as a plant has stomach, and lungs, and heart. In truth, of course, the plant has no such organs, yet what those organs do for you must also be done in some manner by a plant. Though the plant does not have the same organs that animals have, it does have the same general functions to ac- compUsh. Digestion and res- pie, one-celled plant as seen under piration are examples of these a microscope. functions. You have learned of them in your study of physiology. In plants these functions are accomplished by each cell for itself. All this about the internal structure of plants, about cells and protoplasm and the work they do, may not interest you, for it is about things with which you are not familiar and cannot see with your naked eyes. In order to make it interesting, you need to use your imagina- tion. There is need for imagination in connection with the study of science as well as in the study of anything else. For the sake of this lesson it is perhaps a pity that a plant cell is not as big as a tree and as common as a tree in your experience. In importance it is certainly as big as a tree, and you cannot begin to understand a tree until you begin to understand the cells which compose it. Your mind can readily picture a tree. Similarly, let it picture a plant Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Coulter, John G.
