This challenging worksheet asks second graders to think like real botanists about how plants use water and light. Four multiple choice questions cover photosynthesis basics, where water enters through roots, the gas plants take in (carbon dioxide), and how a desert cactus stores water in its thick, fleshy stem.

Five fill-in-the-blank sentences then introduce vocabulary like oxygen, chlorophyll, spines, and stem transport. Students explain why cactus plants have spines instead of flat leaves, why rainforest plants grow large leaves, and what gives leaves their green color. The page connects plant parts to plant survival in different habitats and stretches kids beyond memorized labels.
