Steward et al performed experiment to prove celluar totipotency on

Options

A. Tomato
B. Carrot
C. Tobacco
D. Potato

Answer

**Step-by-Step Solution:**

1. **Understanding Cellular Totipotency**: Cellular totipotency refers to the ability of a single cell to divide and produce all the differentiated cells in an organism, including the extra-embryonic tissues. This means that a totipotent cell can develop into a complete organism.

2. **Identifying the Experiment**: The question refers to an experiment conducted by Steward et al. to demonstrate cellular totipotency. It's important to know the context of this experiment and the organism used.

3. **Reviewing the Options**: The options provided are:
- a. Tomato
- b. Carrot
- c. Tobacco
- d. Potato

4. **Recalling the Experiment Details**: Steward et al. conducted their experiments specifically on the roots of the carrot plant. They demonstrated that cells from the carrot root could regenerate into a whole new plant, thus proving the concept of totipotency.

5. **Selecting the Correct Answer**: Based on the information gathered, the correct answer to the question is option B, carrot.

**Final Answer**: The correct answer is **B. Carrot**.
