Hint: Photosynthesis is a phenomenon where a plant uses water and carbon dioxide in the presence of sunlight and synthesises starch and oxygen is released during the reaction within the chlorophyll.
Complete Answer:
- Photosynthesis is carried out by many molecules such as proteins and glycoproteins within chlorophyll reaction centres.
- Proteins usually work efficiently within optimum temperature. If a plant encounters low temperature the bonds within the proteins which have folded within particular configuration tend to remain stable and thereby decrease the efficiency of its reaction.
- In case of medium temperature enzymes work at optimal level, at this condition the limiting factor will be diffusion of carbon dioxide into leaves. At high temperature enzymes in plants lose their confirmation and become less efficient and hence the rate of photosynthesis is affected.
So the correct answer is option D that is photosynthesis is efficient in 35-50 degree Celsius.
Note: Rate of Photosynthesis depends on temperature and pH and other physical aspects. Maintaining temperature is a necessary aspect in greenhouse farming so only a thermostat is installed to maintain temperature. Rate of increase of temperature gradually increased the rate of photosynthesis by increasing the chance of collision within the photosystem but after a particular temperature the rate of photosynthesis drops due to change in conformation of proteins.
