The correct Answer is:
To solve the question "Which ones have round and biconcave shape?" we need to analyze the options provided: WBCs (White Blood Cells), RBCs (Red Blood Cells), epithelial cells, and nerve cells. ### Step-by-Step Solution: 1. **Identify the Shapes of Each Cell Type**: - **WBCs (White Blood Cells)**: WBCs have an irregular shape. They are not round or biconcave. - **RBCs (Red Blood Cells)**: RBCs are known for their unique biconcave shape, which makes them round and allows for increased surface area for gas exchange. - **Epithelial Cells**: Epithelial cells can have various shapes, including squamous (flat), cuboidal (cube-shaped), and columnar (tall and column-like). None of these shapes are round and biconcave. - **Nerve Cells**: Nerve cells (neurons) have a complex structure with a cell body and long extensions (axons and dendrites), resembling a mushroom shape. They are not round or biconcave. 2. **Conclusion**: - From the analysis above, the only cell type that has a round and biconcave shape is **RBCs (Red Blood Cells)**. ### Final Answer: The correct answer is **RBCs (Red Blood Cells)**. ---
