Largest animal cell is that of

Options

A. Ostrich egg
B. Nerve cell
C. Muscle cell
D. RBC

Answer

To determine the largest animal cell, we can follow these steps:

1. **Identify the Options**: The options given are the ostrich egg, nerve cell, muscle cell, and red blood cell (RBC).

2. **Understand Cell Types**: Recognize that all these options are different types of cells. The ostrich egg is a reproductive cell, while nerve cells and muscle cells are specialized cells in the body. RBCs are unique because they lack a nucleus.

3. **Consider Size**: Eukaryotic cells, which include animal cells, typically range from 5 to 100 micrometers in size. However, the largest animal cell is significantly larger than this range.

4. **Identify the Largest Animal**: The ostrich is known to be the largest living bird and, consequently, has the largest egg among birds.

5. **Conclude with the Largest Cell**: The ostrich egg is not only the largest egg but also contains the largest animal cell, as the egg itself is a single cell with a nucleus.

6. **Final Answer**: Therefore, the largest animal cell is that of the **ostrich egg**.
