Question:
Which one of the following characters does not belong to xerophytic plant?
Which one of the following characters does not belong to xerophytic plant?
Show Hint
Xerophytic plants have fewer stomata on the upper surface to reduce water loss in arid environments.
Updated On: Sep 3, 2025
- Thick cuticle on leaf surface
- Stomata are arranged in deep groove
- Stem starts to perform the function of leaves
- Stomata are found equal in number on both surfaces of leaves
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Define xerophytic adaptations.
Xerophytic plants are adapted to dry conditions. They have features like thick cuticles, stomata located in deep grooves or pits to reduce water loss, and some even have stems that perform photosynthesis in place of leaves.
Step 2: Analyze the options.
- Option ((A): A thick cuticle helps in reducing water loss, typical of xerophytes. - Option ((B): Stomata in deep grooves prevent direct exposure to air, limiting water loss, which is characteristic of xerophytes. - Option ((C): Xerophytes have modified stems (like succulents) that perform photosynthesis when leaves are reduced or absent. - Option ((D): Stomata are usually fewer on the upper surface of xerophytic leaves to reduce water loss, so having equal stomata on both sides is not typical.
Step 3: Conclusion.
The correct answer is ((D), as it is not a characteristic of xerophytic plants.
Final Answer: \[ \boxed{\text{Stomata are found equal in number on both surfaces of leaves}} \]

The Indian National Army plans went away with the defeat of Japan. Subhash Bose was killed in a plane accident while on his way to Tokyo. It is true that many leaders did not like the idea of India winning freedom with the assistance of a country like Japan and her fascist allies. But during the closing years of the war, Subhash Bose and the Indian National Army served to hold up the dropping spirits of the nationalist Indians at home, who were feeling helpless and frustrated. They set before all sections of the Indian people, including those serving in the army, an example of courage and patriotism which was both inspiring and ennobling. Therefore, when the Government announced their decision to prosecute some of the Indian National Army officers for treason because they had broken their oath of loyalty to the British crown, there was a wave of nationalist protest. There were massive demonstrations all over the country. There were persistent demands that the officers should be released.
