Over a 24-hour period, which factor would have the LEAST effect upon the rate of photosynthesis in a geranium plant

Photosynthesis is defined as the process of making food in the presence of sunlight, carbon dioxide, and chlorophyll. It is carried out by algae and plants.

The correct options are:

Option B. Quality of nitrates in the soil

The rate of photosynthesis is highly dependent on the light, concentration of carbon dioxide, and water.

These are the key reactants of photosynthesis, which help the plant prepare food and release oxygen.

The quality of the nitrated in the soil will have the least effect on the rate of photosynthesis of the germanium plant.

Therefore, the correct answer is the quality of nitrate in the soil.

This question lacks options, the options are:

A. Concentration of carbon dioxide in the air

B. Quality of nitrates in the soil

C. Wavelengths of light

D. Availability of water in the soil

The answer is B

Explanation:

Photosynthesis is the process whereby cells of autotrophic organisms manufacture their food in the presence of sunlight. The rate at which the process of photosynthesis occurs, however, is dependent upon certain factors including the concentration of reactants (water and carbon dioxide), availability of light source etc.

Among the options, the concentration/availability of light, carbon dioxide and water, which are key reactants of photosynthesis, will have greater effect on the rate at which the process occurs than the availability of nutrients (nitrates) in the soil. Hence, the quality of nitrates in the soil will have the LEAST effect upon the rate of photosynthesis in a geranium plant.
