Which one of the following pairs is not correctly matched

Options

A. Cristae - The "Shelves'' formed by the folding of the inner membrane of the mitochondrion
B. Plasmodesmata - The membrane surrounding the vacuole in plants
C. Grana - Membrane bound discs in chloroplasts that contain chlorophylls and carotenoids
D. Middle lamella - Layer between adjacent cell walls in plants derived from cell plate

Explanation

To determine which pair is not correctly matched, we will analyze each option provided in the question.

### Step 1: Analyze the first option - Kriste
- **Definition**: Kriste refers to the folds of the inner membrane of mitochondria.
- **Function**: The function of Kriste is to increase the surface area for the electron transport chain reactions.
- **Conclusion**: This pair is correctly matched.

### Step 2: Analyze the second option - Plasmodesmata
- **Definition**: Plasmodesmata are channels that connect adjacent plant cells.
- **Function**: They allow for communication and transport of materials between cells.
- **Incorrect Match**: The option states that Plasmodesmata is a membrane that surrounds the vacuole, which is incorrect. The membrane surrounding the vacuole is called the Tonoplast.
- **Conclusion**: This pair is not correctly matched.

### Step 3: Analyze the third option - Grana
- **Definition**: Grana are stacks of thylakoids found in chloroplasts.
- **Function**: They contain chlorophyll and are involved in the light-dependent reactions of photosynthesis.
- **Conclusion**: This pair is correctly matched.

### Step 4: Analyze the fourth option - Middle Lamella
- **Definition**: The Middle Lamella is the layer that cements adjacent plant cell walls together.
- **Function**: It is formed during cell division from the cell plate and is composed of pectins.
- **Conclusion**: This pair is correctly matched.

### Final Conclusion
The only pair that is not correctly matched is the second option, Plasmodesmata, which is incorrectly described as a membrane surrounding the vacuole instead of being the connection between adjacent cells.
