Which is wrongly matched

Options

A. Sorghum - Kranz anatomy
B. PS II -700
C. Photorespiration `-C_(3)`
D. PEP carboxylase - Mesophyll cells

Answer

To determine which option is wrongly matched, we will analyze each option one by one.

### Step-by-Step Solution:

1. **Option A: Sorghum shows Kranz anatomy.**
- Sorghum is a C4 plant, and C4 plants are characterized by a specialized leaf anatomy known as Kranz anatomy. This option is correctly matched.

2. **Option B: PS2 contains P700.**
- Photosystem II (PS2) actually has a reaction center at P680, not P700. P700 is associated with Photosystem I (PS1). Therefore, this option is incorrectly matched.

3. **Option C: Photorespiration is shown in C3 plants.**
- Photorespiration is a process that occurs in C3 plants, where oxygen is taken up and carbon dioxide is released, leading to a loss of energy. This option is correctly matched.

4. **Option D: PEP carboxylase is found in mesophyll cells.**
- PEP carboxylase is indeed an enzyme found in the mesophyll cells of C4 plants, where it plays a crucial role in carbon fixation. This option is correctly matched.

### Conclusion:
The wrongly matched option is **B: PS2 contains P700**.
