The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question states that every living plant cell should be able to regenerate a whole plant. We need to identify the concept that explains this ability. 2. **Analyzing the Options**: - **Option 1: Cell Theory**: This theory states that all organisms are made up of one or more cells and that all cells arise from pre-existing cells. While important, it does not specifically address the ability of a single cell to regenerate an entire organism. - **Option 2: Protoplasmic Theory**: This theory posits that protoplasm is the physical basis of life. It does not explain the regenerative capabilities of plant cells. - **Option 3: Cell Culture**: This refers to the process of growing cells under controlled conditions. It does not relate to the regeneration of a whole plant from a single cell. - **Option 4: Totipotency**: This is the correct concept. Totipotency refers to the ability of a single cell to divide and develop into a complete organism. In plants, this means that a single living plant cell can regenerate into an entire plant. 3. **Conclusion**: The correct answer to the question is **Totipotency**. ---
