Given below are two statements about guard cells of stomata in plants.
Statement I - In monocotyledonous plants, guard cells are usually dumbbell shaped.
Statement II - In Cyperus, a monocot plant, the guard cells are also kidney shaped.
In the light of above statements, choose the correct option given below:
Statement I - In monocotyledonous plants, guard cells are usually dumbbell shaped.
Statement II - In Cyperus, a monocot plant, the guard cells are also kidney shaped.
In the light of above statements, choose the correct option given below:
Options
- ABoth statement I and statement II are correct.
- BBoth statement I and statement II are incorrect.
- CStatement I is correct but statement II is incorrect.
- DStatement I is incorrect but statement II is correct.
Correct answer
B. Both statement I and statement II are incorrect.
Step-by-step solution
Statement I is incorrect. In most monocotyledonous plants, the guard cells are kidney-shaped (bean-shaped). Dumbbell-shaped guard cells are a specific characteristic feature primarily restricted to the families Poaceae (grasses) and Cyperaceae (sedges). Therefore, it is incorrect to generalize that monocots "usually" have dumbbell-shaped guard cells.
Statement II is incorrect. Cyperus belongs to the family Cyperaceae (sedges). As a member of this family, its guard cells are dumbbell-shaped, not kidney-shaped.
Therefore, both Statement I and Statement II are incorrect.
Answer: Both statement I and statement II are incorrect.
Statement II is incorrect. Cyperus belongs to the family Cyperaceae (sedges). As a member of this family, its guard cells are dumbbell-shaped, not kidney-shaped.
Therefore, both Statement I and Statement II are incorrect.
Answer: Both statement I and statement II are incorrect.
