Temperature
2. What happens to the rate of photosynthesis if light intensity is too low?
It increases rapidly.
It decreases.
It stays the same.
It stops completely.
3. The pigment inside plant cells that absorbs light energy for photosynthesis is called .
4. Plants take in gas from the atmosphere for photosynthesis.
5. The ideal temperature range for most plants to perform photosynthesis efficiently is between and degrees Celsius.
