Question 1:
State three main factors affecting the rate of photosynthesis.
Answer:
Light intensity, temperature and carbon dioxide concentration
State three main factors affecting the rate of photosynthesis.
Answer:
Light intensity, temperature and carbon dioxide concentration
Question 2:
State the effects of different light intensities on the rate of photosynthesis.
Answer:
At low light intensities, the stomata will close and lower the rate of photosynthesis. At high light intensities, the stomata will open and until it reaches a point. After the point, the rate of photosynthesis does not increase because other factors become limiting factors.

Question 3:
Mr. Kumar has succeeded in planting a grape plant in a greenhouse in Cameron Highlands. List the equipment needed.
Answer:
Supply of water, bulb with appropriate light intensity, adjustable heater at 25 oC, optimum temperature for enzyme reaction in photosynthesis and carbon dioxide source.

Answer:
Supply of water, bulb with appropriate light intensity, adjustable heater at 25 oC, optimum temperature for enzyme reaction in photosynthesis and carbon dioxide source.
Question 4:
Do you agree with this statement? Explain.
Answer:
Agree. A light-independent reaction requires NADPH and ATP which is produced in a light-dependent reaction.
| Light-independent reaction depends on the light-dependent reaction. |
Answer:
Agree. A light-independent reaction requires NADPH and ATP which is produced in a light-dependent reaction.
