The correct Answer is:
To solve the question of identifying the incorrect statements, we will analyze each statement one by one. ### 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 well-defined nucleus and membrane-bound organelles. Therefore, this statement is **correct**. 2. **Statement 2: WBC is amoeboid in shape.** - White blood cells (WBCs) are known for their ability to change shape, and they exhibit an amoeboid form, which allows them to move and engulf pathogens. Thus, this statement is **correct**. 3. **Statement 3: Mycoplasma is the largest cell.** - Mycoplasma is a genus of bacteria that is known to be the smallest known cellular organisms. They lack a cell wall and are much smaller than typical bacterial cells. Therefore, this statement is **incorrect**. 4. **Statement 4: Microbodies are cell organelles.** - Microbodies, which include peroxisomes and glyoxisomes, are indeed considered cell organelles. They perform various functions within the cell. Thus, this statement is **correct**. 5. **Statement 5: Prokaryotes do not exhibit a wide variety of shapes.** - Prokaryotes, especially bacteria, exhibit a wide variety of shapes including cocci (spherical), bacilli (rod-shaped), and spirilli (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 statements 3 and 5.
