Question

Observe the graph between light intensity and rate of photosynthesis.

Choose the correct match w.r.t. A, C, D, E mentioned in the graph.

• A. A(ii), B(i), C(iv), D(iii)
• B. A(iv), B(iii), C(ii), D(i)
• C. A-(iii), B-(iv), C-(i), D-(ii)
• D. A(iv), B(iii), C(i), D(ii)

Answer 1

The correct option is C A-(iii), B-(iv), C-(i), D-(ii)

A- Under low light intensity, the rate of photosynthesis is directly proportional to increasing light intensity.
C- Limiting factors for rate of photosynthesis are water, temperature, ${\mathrm{CO}}_2$ concentration, but not light. After 10% of total sunlight, the rate of photosynthesis gets saturated.
D- Value of light intensity after which there is no increase in rate of photosynthesis.
E- Maximum rate of photosynthesis.
