Question

True xerophytes have

• A. Lower rate of transpiration than mesophytes
• B. Transpiration rate equal to mesophytes
• C. Transpiration rate higher than mesophytes
• D. No transpiration

Answer 1

The correct option is A Lower rate of transpiration than mesophytes

In dry environments, a typical (mesophytic) plant would evaporate water faster than the rate at which water was replaced in the soil, leading to wilting. To reduce this effect, xerophytic plants exhibit a variety of specialized adaptations to survive in such conditions. Xerophytes use water from their own storage, allocate water specifically to sites of new tissue growth, or lose less water to the atmosphere and so convert a greater proportion of water in the soil to growth

So, the correct answer is 'Lower rate of transpiration than mesophytes'
