- A plant cannot photosynthesise very quickly without enough light.
- Eventhough There is plenty of Carbon dioxide,water and suitable temperature is available.
Explanation:
Stomata are tiny openings or pores in plant tissue that allow for gas exchange. Stomata are typically found in plant leaves but can also be found in some stems. Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.
The second option because solar energy is a renewable source which can be used again.
