(2)WBC is amoeboid in shape.
(3) Mycoplasma is the largest cell.
(4) Microbodies are cell organelles.
(5) Prokaryotes do not exhibit a wide variety of shapes.

Options

A. 2,4 and 5
B. 2,3 and 5
C. 3,4 and 5
D. 3 and 5 only

Answer

To solve the question, we need to analyze each statement and determine whether it is correct or incorrect. Let's go through each statement step by step.

### Step-by-Step Solution:

1. **Statement 1: Blue-green alga is a prokaryotic cell.**
- Blue-green algae, also known as cyanobacteria, are indeed prokaryotic organisms. They lack a true nucleus and membrane-bound organelles. Therefore, this statement is **correct**.

2. **Statement 2: WBC is amoeboid in shape.**
- White blood cells (WBCs) are known to have an amoeboid shape, which allows them to move and engulf pathogens. This statement is also **correct**.

3. **Statement 3: Mycoplasma is the largest cell.**
- Mycoplasma are actually the smallest known cells and do not have a cell wall. This statement is **incorrect** because it claims that Mycoplasma is the largest cell.

4. **Statement 4: Microbodies are cell organelles.**
- Microbodies, such as peroxisomes and glyoxysomes, are indeed considered cell organelles. This statement is **correct**.

5. **Statement 5: Prokaryotes do not exhibit a wide variety of shapes.**
- Prokaryotes, particularly bacteria, can exhibit a wide variety of shapes, including cocci (spherical), bacilli (rod-shaped), and spirilla (spiral-shaped). Therefore, this statement is **incorrect**.

### Conclusion:
The incorrect statements are:
- Statement 3: Mycoplasma is the largest cell.
- Statement 5: Prokaryotes do not exhibit a wide variety of shapes.

### Final Answer:
The incorrect statements are 3 and 5.
