This challenging worksheet pulls together everything second graders know about how plants live and grow. Four multiple choice questions ask students to put the life cycle in order from seed to sprout to adult plant to flower, explain why flowers are colorful, predict what happens to a plant with no water, and identify the stem as the part that holds the plant up and carries water.

Five fill-in-the-blank sentences then push deeper into pollination, seed making, and the role of leaves in photosynthesis. Students explain that pollen travels by insects or wind, that fruit grows around seeds to protect them, and that a plant without leaves cannot make food. The page rewards careful thinking about cause and effect.
