🌱 What is Photosynthesis?

Photosynthesis is the amazing process that plants use to make their own food! Plants take in sunlight, water, and carbon dioxide from the air to create glucose (sugar) for energy and release oxygen as a waste product. This process happens mainly in the leaves of plants.

The equation for photosynthesis is:
Sunlight + Water + Carbon Dioxide → Glucose + Oxygen

📚 Part 1: Multiple Choice Questions

1. What do plants need to carry out photosynthesis?

Sunlight, water, and carbon dioxide

✏️ Part 2: Fill in the Blanks and Short Answers

5. Complete the photosynthesis equation:

_______________ + _______________ + Carbon Dioxide → Glucose + _______________

6. Fill in the blanks:

Plants absorb _______________ through their roots and take in _______________ from the air through tiny holes in their leaves called stomata. The green substance in leaves called _______________ captures sunlight energy to power photosynthesis.

7. Label the diagram: Draw arrows and label where sunlight, water, carbon dioxide enter the plant, and where oxygen is released.

8. Why is photosynthesis important for life on Earth?
