Factors Affecting Photosynthesis - NEET MCQ

Frederick Frost Blackman proposed the law of limiting factors. Blackman proposed this law in 1905 according to which, a chemical process depends on multiple factors the rate of the process will be limited by the pace of the slowest factor or limiting factor.

Chloroplasts are specialized subunits, in plant and algal cells. Their main role is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures  energy from sunlight and converts it into glucose with the help of various enzymes

The genetic predisposition or the genetic make up of a plant is an internal factor that affects the rate of photosynthesis. The arrangement of genes present in the plant is expressed in a certain way in different plants.

Answer: B.

Solution: Chlorophyll's primary role in photosynthesis is to absorb sunlight and convert it into chemical energy. This process is crucial for driving the light-dependent reactions, where the absorbed light energy is used to produce ATP and NADPH, which are then utilized in the Calvin cycle to fix carbon dioxide into carbohydrates
