Cell cycle is the character of-

Options

A. Only bacteria
B. Only plants and animals
C. Only protists
D. All organisms

Answer

**Step-by-Step Solution:**

1. **Understanding the Cell Cycle**: The cell cycle is a series of phases that a cell goes through to grow and divide. It is a fundamental characteristic of all living organisms.

2. **Phases of the Cell Cycle**: The cell cycle consists of several phases:
- **G1 Phase (Gap 1)**: The cell grows and prepares for DNA replication.
- **S Phase (Synthesis)**: DNA is replicated, resulting in two copies of each chromosome.
- **G2 Phase (Gap 2)**: The cell continues to grow and prepares for mitosis.
- **M Phase (Mitosis)**: The cell divides to form two daughter cells.

3. **Applicability to Organisms**: The cell cycle is not limited to a specific type of organism. It is a characteristic feature of:
- Bacteria (though they divide differently, they still undergo a form of the cell cycle)
- Plants
- Animals
- All other living organisms

4. **Conclusion**: Since the cell cycle is a universal characteristic of all organisms, the correct answer to the question is option number 4, which states that the cell cycle is a characteristic of all organisms.

**Final Answer**: The cell cycle is the character of all organisms.
