Question:
Stomatal transpiration takes place during day time in the following plants EXCEPT __________
Stomatal transpiration takes place during day time in the following plants EXCEPT __________
Show Hint
Plants with CAM metabolism open stomata at night.
Updated On: Nov 13, 2026
lotus
mango
grass
cactus
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Most plants keep stomata open in the day, but xerophytes such as cacti open stomata at night to save water.
Step 2: Compare the options
Lotus, mango and grass transpire through stomata in the day, while cactus does not.
Step 3: Conclusion
Therefore, cactus is the exception.
Final Answer:
Cactus is the exception. \[ \boxed{\text{(D) }\text{cactus}} \]
