The basic feature of typical `C_(4)` plants showing 'Kranz' anatomy is

Options

A. the presence of chloroplasts in bundle heath and epidermal cells
B. the presence of chlorplasts in mesophyll and epidermal cells
C. the presence of typical chloroplasts with well-formed grana in bundle sheath cells and rudimentary chloroplasts in the mesophyll cells
D. the presence of non granal chloroplasts in bundle sheath cells and typical granal chloroplasts in mesophyll cells

Answer

### Step-by-Step Solution:

1. **Understanding C4 Plants**: C4 plants are a group of plants that utilize a specific photosynthetic pathway, which is different from the more common C3 pathway. They are adapted to high temperatures and light intensities.

2. **Kranz Anatomy**: The term 'Kranz' refers to the unique leaf structure found in C4 plants. This anatomy is characterized by the arrangement of bundle sheath cells and mesophyll cells around the vascular bundles.

3. **Chloroplast Distribution**: In C4 plants, the bundle sheath cells contain a high number of chloroplasts that are typically agranal (without granules). In contrast, the mesophyll cells surrounding the bundle sheath cells contain granal chloroplasts (with granules).

4. **Vascular Bundles**: The vascular bundles in C4 plants are surrounded by these specialized bundle sheath cells, which are thick-walled and have no intracellular spaces. This structure is crucial for the efficient capture of carbon dioxide and the subsequent photosynthetic process.

5. **Correct Option Identification**: Based on the characteristics of C4 plants:
- The correct description is that there are non-granule chloroplasts in bundle sheath cells and typical granule chloroplasts in mesophyll cells.

### Final Answer:
The basic feature of typical C4 plants showing 'Kranz' anatomy is the presence of non-granule chloroplasts in bundle sheath cells and typical granule chloroplasts in mesophyll cells.
