Which of the following cell does not divide ?

Options

A. Nerve cell
B. Yeast
C. Apical meristematic cell
D. E, coli

Answer

To determine which of the following cells does not divide, we will analyze each option provided:

**Step 1: Understand the types of cell division**
- Cell division occurs primarily through two processes: mitosis and meiosis. Cells can also enter a phase known as the G0 phase, where they lose the ability to divide and often differentiate into specialized cells.

**Step 2: Analyze the options**
- **Option A: Nerve cell**
- Nerve cells, or neurons, are specialized cells that conduct nerve impulses. They lack centrioles, which are essential for the formation of spindle fibers during mitosis. As a result, nerve cells do not divide and remain in the G0 phase after differentiation. Therefore, this option is likely correct.

- **Option B: Yeast**
- Yeast is a unicellular eukaryote and belongs to the fungi kingdom. Yeast cells can reproduce asexually through budding or fission, indicating that they do divide. Hence, this option is incorrect.

- **Option C: Apical meristematic cell**
- Apical meristematic cells are found in plants and are responsible for growth. These cells are actively dividing and are crucial for the elongation of roots and shoots. Therefore, this option is also incorrect.

- **Option D: E. coli**
- E. coli is a type of bacteria that reproduces rapidly through binary fission, typically every 20-30 minutes. This indicates that E. coli cells do divide. Thus, this option is incorrect.

**Step 3: Conclusion**
- After analyzing all the options, we conclude that the correct answer is **Option A: Nerve cell**, as nerve cells do not divide due to the absence of centrioles and remain in the G0 phase.
