Question

Plants adapted to low light intensity have:

• A. Higher rate of $C{O}_2$ fixation than the sun plants
• B. More extended root system
• C. Leaves modified to spines
• D. Larger photosynthetic unit size than the sun plants

Answer 1

The correct option is D Larger photosynthetic unit size than the sun plants

They have larger photosynthetic unit size so that they can absorb maximum amount of light of the photosynthetically active radiation (PAR) for photosynthesis.
