4. Compare and Contrast Which kind of plant–a sun plant or a shade plant-has a higher rate of photosynthesis when light intensity is below 200 umol photons/mº/s?
When light intensity is above 400 umol photons/mº/s?

Below 200 umol photons/mº/s, shade plant grow best.

Above 400 umol photons/mº/s, sun plant grow best.

Explanation:

A shade plant has a  higher rate of photosynthesis when light intensity is present below 200 umol photons/mº/s because shade plants needs low light intensity for higher photosynthesis while on the other hand, a sun plant has a  higher rate of photosynthesis when light intensity is above 400 umol photons/mº/s because it requires high intensity of light for photosynthesis if other factors are also present in large amount such as water and nutrients in the soil.
