Excerpt from Elementary Plant Biology In the judgment Of the authors the kind of biology most worth while for the average boy or girl of fourteen years Of age is not' one based primarily on structure. Young stu dents are naturally more interested in activities or func tions than they are in mere form or structure. Hence, if we wish to work with, rather than against the grain, we must put function in the foreground of our discussion. Every boy and girl knows, too, that both plants and animals as well as human beings must have food and drink, and that they grow and reproduce their kind. It is relatively much easier, therefore, to unify a course like this along physiological lines than on the basis of morphology, or of homologies of structure, many of which are far too complicated to be made clear to young students.
