- Both statement I and statement II are correct.
- Both statement I and statement II are incorrect.
- Statement I is correct but statement II is incorrect.
- Statement I is incorrect but statement II is correct.
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Statement I
Dumbbell-shaped guard cells are found in grasses and sedges. Most other monocots have kidney-shaped guard cells. So saying they are usually dumbbell shaped in monocots is not correct.
Step 2: Statement II
Cyperus is a sedge. Like grasses, it has dumbbell-shaped guard cells, so saying they are kidney shaped is wrong.
Step 3: Conclusion
Both statements are incorrect.
Final Answer:
Both statements are incorrect. \[ \boxed{\text{(B) }\text{Both statement I and statement II are incorrect.}} \]
