The correct Answer is:
To solve the question regarding the shape of guard cells of stomata in grasses, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Question**: The question asks about the shape of guard cells of stomata specifically in grasses. 2. **Identify the Options**: The options given are: - (a) Bean-shaped - (b) Kidney-shaped - (c) Sickle-shaped - (d) Dumb-bell shaped 3. **Recall the Shapes of Stomata**: Stomata can have different shapes based on the type of plant. The two main shapes identified in plants are: - Kidney-shaped stomata - Dumbbell-shaped stomata 4. **Focus on Grasses**: It is important to note that grasses typically have a narrow leaf blade. In these plants, the guard cells are adapted to this structure. 5. **Determine the Correct Shape**: In grasses, the guard cells are specifically described as being dumbbell-shaped. This shape is more efficient for the function of stomata in grasses compared to kidney-shaped stomata. 6. **Select the Correct Option**: Based on the information gathered, the correct answer to the question is: - (d) Dumb-bell shaped ### Final Answer: The guard cells of stomata in grasses are (d) Dumb-bell shaped. ---
