About this worksheet
A first grader may know the words root, stem, leaf, and flower without understanding how those parts help a plant meet its needs. This page connects structure to function. Roots take in water and hold the plant in place, stems support the plant and carry water, leaves receive light, and flowers help many plants make seeds. The questions also separate what plants need from things people may give them by mistake. Plants need water, light, air, and room to grow; they do not need toys or milk. Exact diagrams leave the target label blank so children must use the part’s position and job rather than copy its name. Difficulty increases through less direct clues and problems that combine a part with a need. If your child names a part but cannot explain its job, return to the diagram and trace where water or light would travel.
What your child will learn
Name four main plant parts
Match each part to its job
Identify water, light, air, and space as needs
Use a diagram to explain plant growth
Worked example
Roots are below the stem. They take in water from the soil and help hold the plant in place.
Common mistake
Saying a plant gets its food from soil instead of recognizing that light helps leaves make food.
