Question

What will be the effect, when a very high intensity of light is supplied to a photosynthesis system?
A. Process will increase
B. Process will decrease
C. Process will stop due to solarization
D. None of the above

Answer 1

The process of photosynthesis requires light in order to produce food in the plants. The light intensity required by plants in order to make food is limited and both low and high intensity of light leads to a cause an effect on the process of photosynthesis in the plants.

Complete answer: The plants need 400 to 700 nm wavelength of light in order to perform the process of photosynthesis. The light intensity below and above this wavelength adversely affect the photosynthesis in the plants. Plants generally acquire wavelengths from blue and red light and if the intensity of light increases it will lead to no photosynthesis in the plants as the chloroplast present in the plants would not be able to trap this light. The high intensity of light leads to an effect on chloroplast present on the leaves of the plants as it will not be able to trap the high-intensity light which could also damage the chloroplast of the plants. The process of photosynthesis will stop due to solarization which means that due to the high intensity of light from the sun, the chlorophyll will not be able to make food by converting light into energy molecules.
Hence, the correct option is C, Process will stop due to solarization.

Note: The chlorophyll present in the leaves of the plants can only perform their activity in presence of the light of appropriate wavelength as they cannot function with low and high intensity of light. These chloroplasts can also damage due to a very high intensity of light.
