Question

Plants adapted to low light intensity have what modification?

• A. Leaves are modified to spines.
• B. Presence of large photosynthetic unit with size more than that of sun plants.
• C. Fix CO${}_2$ at a rate higher than the sun plants.
• D. A more extended root system.

Answer 1

The correct option is B Presence of large photosynthetic unit with size more than that of sun plants.

Plants have specific requirement of the light. It is a common observation, that plants growing in shade have dark green leaves as compared to the plants growing in sun. The shade loving plants have more chlorophyll content. This is an adaptation to help shade growing plants capture the optimum amount of light for the process of photosynthesis. In other words, plants adapted to low light intensity, have larger photosynthetic unit size than the plants growing in bright sunlight.

So, the correct answer is option B.
