🌱 Part 1: Photosynthesis Knowledge Check

1. What is the chemical equation for photosynthesis?

CO₂ + H₂O + light energy → C₆H₁₂O₆ + O₂

C₆H₁₂O₆ + O₂ → CO₂ + H₂O + energy

N₂ + O₂ → NO₂

2. Which parts of a plant are involved in photosynthesis? (Select all that apply)

Leaves

Stems (green parts)

Roots

Chloroplasts

3. What colour of light is LEAST useful for photosynthesis?

Red

Blue

Green

Violet

4. At what temperature range (°C) does photosynthesis work most efficiently in most plants?

5-15°C

20-30°C

35-45°C

50-60°C

🔬 Part 2: Research Challenge

5. Research and name one plant species native to New Zealand that has adapted unique photosynthesis strategies. Explain what makes it special.

6. Complete this sentence using research: CAM photosynthesis is used by plants like _____________ because it helps them survive in _____________ environments by _____________.

7. Research the "light reactions" vs "dark reactions" in photosynthesis. In your own words, explain the main difference between these two stages.

🎨 Part 3: Creative Connection

8. Design an experiment to test one factor that affects photosynthesis rate. Describe your hypothesis, method, and what you would measure.

9. Research and explain: How does photosynthesis in ocean phytoplankton differ from photosynthesis in land plants? Why is this important for Earth's atmosphere?
