Abstract
Shows the factors required by green plants for life and growth: sunlight, carbon dioxide, water, and soluble minerals; and describes the process of photosynthesis, by which chemical compounds are combined and changed within the plant to make food. Stresses the concept that all living things depend directly or indirectly on food make by green plants. (WorldCat)
