The difference between human nutrition and plant nutrients is often one of the concepts that students misunderstand. This is proven in documented errors found in standardized test questions. Students hear the term “plant food” and take that term literally, believing that plants eat (as animals do) to obtain nutrients. The intent of this lesson is to clear up that misconception as well as to teach students about the actual nutrients that plants require and the source of those nutrients.
