Question
Biology Question on Plant Growth and Development
Plants adapted to low light intensity have
A
Higher rate of CO2 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
Larger photosynthetic unit size than the sun plants
Explanation
Solution
These plants possess a greater photosynthetic unit size compared to sun-exposed plants. This larger unit size enables them to capture the maximum available amount of photosynthetically active radiation (PAR) light for the process of photosynthesis.
