Question

Given below are two statements:
Statement (I) : The Photosynthetic Photon Flux Density (PPFD) at which the $\text{CO}_2$ uptake by photosynthesis is exactly equal to $\text{CO}_2$ released through respiratory process is called Light Compensation Point (LCP).
Statement (II) : LCP of sun plants range from $1 - 5\text{ }\mu\text{mol m}^{-2}\text{ s}^{-1}$, whereas the corresponding values for shade plants are $10 - 20\text{ }\mu\text{mol m}^{-2}\text{ s}^{-1}$.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Shade-adapted plants have lower light compensation points ($1-5\text{ }\mu\text{mol m}^{-2}\text{ s}^{-1}$) and lower light saturation points than sun-adapted plants.
This adaptation allows them to maintain a positive carbon balance even in deeply shaded environments.

Answer 1

The Correct Option is C
