Theory of Biogenesis explains

Options

A. origin of first life
B. Life arising from pre-existing lifw
C. Life camera from outer space
D. Creation of lfe by super natural power

Answer

### Step-by-Step Solution:

1. **Understanding the Theory of Biogenesis**:
- The theory of biogenesis is a scientific principle that states that life arises from pre-existing life, rather than from non-living matter. This concept was established to counter the idea of spontaneous generation, which suggested that life could arise from inanimate objects.

2. **Historical Context**:
- The theory was proposed by Rudolf Virchow in 1858. He emphasized that all living organisms come from other living organisms. This was a significant shift in understanding the origins of life.

3. **Key Phrase**:
- Virchow's famous phrase "Omnis Cellulae Cellula" translates to "every cell is born from another cell." This indicates that life is a continuous chain, where each new life form originates from a pre-existing one.

4. **Supporting Evidence**:
- The theory was further supported by Louis Pasteur in the early 1860s, who conducted experiments that demonstrated that microorganisms arise from other microorganisms, not from spontaneous generation.

5. **Evaluating the Options**:
- **Option A**: Origin of first life - Incorrect, as biogenesis does not explain the origin of the first life.
- **Option B**: Life originating from pre-existing life - Correct, as this is the core principle of biogenesis.
- **Option C**: Life came from outer space - Incorrect, as there is no scientific evidence supporting this hypothesis.
- **Option D**: Creation of life by supernatural power - Incorrect, as this is not a scientific explanation.

6. **Conclusion**:
- The theory of biogenesis explains that life originates from pre-existing life forms, making option B the correct answer.
