Periplastidial space is found in

Options

A. between two membranes of a chloroplast.
B. between two thylakoids
C. between two intergrana lamellae.
D. between lumen of thylakoids

Answer

To solve the question regarding where the periplastidial space is found, follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Periplastidial Space":**
- The periplastidial space refers to a specific area associated with plastids, particularly chloroplasts. It is crucial to know its location to answer the question correctly.

2. **Identify the Structure of Chloroplasts:**
- Chloroplasts are surrounded by two membranes: an outer membrane and an inner membrane. Between these two membranes lies a space.

3. **Locate the Periplastidial Space:**
- The periplastidial space is specifically located between the outer and inner membranes of the chloroplast. This area is also referred to as the intermembrane space.

4. **Evaluate the Options Provided:**
- Option 1: Between two membranes of chloroplast - This is correct as it describes the periplastidial space accurately.
- Option 2: Between two phthalate quites - This option is incorrect.
- Option 3: Between two intergana lamellae - This option is also incorrect.
- Option 4: Between lumen of phthalate quites - This option is incorrect as well.

5. **Conclusion:**
- The correct answer is **Option 1**, as the periplastidial space is found between the two membranes of the chloroplast.

### Final Answer:
**The periplastidial space is found in the chloroplast, specifically between the two membranes of the chloroplast.**
