Cell Shape and Type Analysis
The question asks to identify the INCORRECT statement regarding cell types and their shapes.
Analyzing Cell Shapes
- Muscle Cell Shape: Muscle cells are typically elongated and spindle-shaped, which aids in contraction. Statement 1 is correct.
- Red Blood Cell (RBC) Shape: RBCs have a characteristic biconcave disc shape, meaning they are disc-shaped with a depression in the center. This shape increases surface area for gas exchange. Statement 2 is correct.
- White Blood Cell (WBC) Shape: White blood cells are known for their motility and ability to change shape (amoeboid movement) to perform functions like phagocytosis and migrating through tissues. They do not possess a fixed, round shape. Statement 3 is incorrect.
- Nerve Cell Shape: Nerve cells (neurons) are highly specialized with a cell body, dendrites, and a long axon, making them characteristically long and branched. Statement 4 is correct.
Conclusion on Incorrect Statement
The statement that the white blood cell (WBC) has a round and fixed shape is factually incorrect because WBCs are known to change shape.
