Cells originate

Options

A. from pre existing cells
B. from abiotic materials
C. by bacterial fermentation
D. by regeneration ofold cells

Answer

### Step-by-Step Solution:

1. **Understanding Cells**:
- Cells are the basic structural and functional units of living organisms. They are often referred to as the "building blocks of life."

2. **Cell Theory**:
- According to the cell theory, one of the fundamental principles in biology, all cells arise from pre-existing cells. This means that new cells are formed from the division of existing cells.

3. **Biotic vs. Abiotic Factors**:
- Biotic factors refer to living components that can influence the origin of cells, such as other cells and biomolecules.
- Abiotic factors include non-living components like light, temperature, and pH. These factors do not contribute to the origination of cells.

4. **Conclusion**:
- Based on the cell theory and the distinction between biotic and abiotic factors, we conclude that cells originate from pre-existing cells, not from abiotic factors.

### Final Answer:
Cells originate from pre-existing cells, as stated in the cell theory.
