In Hatch and Slack pathway

Options

A. has chloroplasts of same type
B. occurs in Kranz anatomy where mesophyll cells have small granal chloroplast and bundle sheath cells have agranal chloroplast
C. occurs in Kranz anatomy when mesophyll have small chloroplast whereas bundle sheath have larger granal chloroplasts
D. occurs in Kranz anatomy where mesophyll cells are diffused

Answer

### Step-by-Step Solution:

1. **Understanding the Hatch and Slack Pathway**:
The Hatch and Slack pathway, also known as the C4 pathway, is a photosynthetic process that occurs in certain plants, allowing them to efficiently fix carbon dioxide.

2. **Kranz Anatomy**:
In C4 plants, the structure of the leaves is specialized, known as Kranz anatomy. This anatomy consists of two types of cells: mesophyll cells and bundle sheath cells.

3. **Chloroplast Types in Cells**:
- **Mesophyll Cells**: In C4 plants, mesophyll cells contain small chloroplasts. These cells are responsible for capturing carbon dioxide and initiating the photosynthetic process.
- **Bundle Sheath Cells**: These cells have larger, granule-type chloroplasts. They are located around the vascular bundles and are involved in the Calvin cycle, where the fixed carbon is converted into sugars.

4. **C4 Cycle Characteristics**:
The C4 cycle involves the fixation of carbon dioxide into a four-carbon compound (hence the name C4). The first stable compound formed in this pathway is oxaloacetic acid (OAA).

5. **Conclusion**:
Based on the characteristics of the Hatch and Slack pathway and the structure of the chloroplasts in mesophyll and bundle sheath cells, the correct answer to the question is that this pathway occurs in Kranz anatomy where mesophyll cells have small chloroplasts and bundle sheath cells have larger granule chloroplasts.

### Final Answer:
The Hatch and Slack pathway occurs in Kranz anatomy, where mesophyll cells have small chloroplasts and bundle sheath cells have larger granule chloroplasts.
