The correct Answer is:
### Step-by-Step Solution: 1. **Identify the Question**: The question asks who stated that "cell arises from pre-existing cells." 2. **Review the Options**: The options provided include various scientists. We need to evaluate each option to find the correct answer. 3. **Evaluate Option A - Heckel**: - Heckel was known for proposing notions related to evolutionary descent, not specifically about cell theory. Therefore, this option is incorrect. 4. **Evaluate Option B - Virchow**: - Rudolf Virchow stated "Omnis cellula e cellula," which translates to "all cells come from cells." This statement was made in 1858 and is a fundamental concept in cell theory. This option is correct. 5. **Evaluate Option C - Hooke**: - Robert Hooke is known for discovering cells by examining cork under a microscope, but he did not state that cells arise from pre-existing cells. Thus, this option is incorrect. 6. **Conclusion**: The correct answer is **Option B - Virchow**, as he articulated the principle that cells arise from pre-existing cells.
