In kranz anatomy, the bundle sheath cells have

Options

A. a) thin walls, many intercellular spaces and no chloroplasts
B. b) thick walls, no intercellular spaces and large number of chloroplasts
C. c) thin walls, no intercellular spcaes and several chloroplasts
D. d) thick walls, many intercellular spcaes and few chloroplasts.

Answer

To solve the question regarding Kranz anatomy and the characteristics of bundle sheath cells, we can follow these steps:

### Step 1: Understand Kranz Anatomy
Kranz anatomy is a specialized structure found in C4 plants. It involves two types of cells: mesophyll cells and bundle sheath cells.

### Step 2: Identify the Role of Bundle Sheath Cells
Bundle sheath cells are located around the vascular bundles in C4 plants. They play a crucial role in the C4 photosynthetic pathway, which is efficient in hot and dry environments.

### Step 3: Analyze the Characteristics of Bundle Sheath Cells
- **Chloroplasts**: Bundle sheath cells contain a large number of chloroplasts, which are essential for photosynthesis.
- **Cell Walls**: These cells have thick walls, which help in maintaining the integrity of the vascular bundles.
- **Intercellular Spaces**: Bundle sheath cells typically do not have intercellular spaces, allowing for efficient transport of photosynthetic products.

### Step 4: Compare with the Given Options
Now, let's evaluate the options provided in the question:
- **Option A**: Thin walls and many intercellular spaces and no chloroplasts (Incorrect)
- **Option B**: Thick walls, no intercellular spaces, and a large number of chloroplasts (Correct)
- **Option C**: Thin walls, no intercellular spaces, and several chloroplasts (Incorrect)
- **Option D**: Thick walls, many intercellular spaces, and few chloroplasts (Incorrect)

### Conclusion
Based on the analysis, the correct answer is **Option B**: Thick walls, no intercellular spaces, and a large number of chloroplasts.
