Which would have the GREATEST effect on the rate of photosynthesis in a plant? A) oxygen level B) light intensity C) sugar concentration D) starch concentration

Respuesta :

Oxygen levels make no impact, they need CO2.
Sugar concentration makes no impact as that is a product.
Starch makes no impact.
Only light from the choices above is the factor in photosynthesis that could have the greatest effect as it is not a product yet a reactant

The correct answer is option B, Light intensity

Reason -

Light intensity plays a major role in the regulation of photosynthesis. In the absence of light a plant is unable to photosynthesize. As the plant receives light through the chlorophyll , essential chemical reactions takes place thereby releasing free electrons which keep on driving the further processes or reactions in a plant to produce food and oxygen and energy..  

The higher the light intensity, the higher is the rate of photo synthesis
