1. Taken in from the air through leaf pores

2. Energy source that drives the reaction

3. Taken up by roots and moved to leaves

✏️ Part 2: Short Answers & Activities

I can... explain photosynthesis, identify its reactants and products, and label a simple diagram.

Success criteria: I correctly label reactants and products, write the photosynthesis equation, and explain why sunlight is needed.

Differentiation & supports: Color-coded diagrams and an audio recording are available; use headphones or the printed color key. Kinesthetic learners should use models during class activity. Bilingual vocabulary cards (English/Spanish) can be requested.

Extension (advanced learners): Research one plant adaptation (e.g., cactus, water lily) and explain how it changes photosynthesis. Write your answer below.

5. Fill in the blanks to complete the simplified photosynthesis equation:

________ + ________ + sunlight → ________ + ________

6. In one sentence, explain why sunlight is essential for photosynthesis:

7. Draw and label a simple leaf showing where carbon dioxide enters, where water enters, and where oxygen exits. Then write one sentence naming where glucose is stored.

8. Extension (optional): Name one plant with a special adaptation that affects photosynthesis and briefly explain how the adaptation helps the plant.
