Finally, we stitch it back to the big picture: how physiology underpins development, and how both shape the plants that feed, clothe, and shelter us. For assessment, each student proposes a short, doable experiment inspired by the book: altering light quality to influence flowering time, testing a compost tea’s effect on root growth, or comparing water-conservation traits between cultivars. They must outline methods, expected mechanisms (from the text), and simple, measurable outcomes.
