During regeneration, modification of an organ to other organ is known as : -

Options

A. morphogenesis
B. epimorphosis
C. morphallaxis
D. acretopmaruy growth

Explanation

To solve the question "During regeneration, modification of an organ to another organ is known as:", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Regeneration**: Regeneration is the process by which organisms can replace or restore lost or damaged body parts. It often involves the modification of existing tissues.

2. **Identify the Options**: The options given are Morphogenesis, Apimorphosis, Morphalexis, and Atriparatory growth. We need to analyze each term to find the correct answer.

3. **Analyze Morphogenesis**:
- Morphogenesis refers to the development and arrangement of new body structures. While it is related to regeneration, it does not specifically refer to the modification of one organ into another.

4. **Analyze Apimorphosis**:
- Apimorphosis is a term used to describe the regeneration process in certain organisms, such as amphibians, where lost limbs are replaced by the growth of new cells. This process involves cell proliferation but does not involve the modification of one organ into another.

5. **Analyze Morphalexis**:
- Morphalexis is the process where existing cells modify to form new structures. For example, in Hydra, when it is cut, the remaining cells can modify to form new tentacles and a head. This directly relates to the modification of one organ into another during regeneration.

6. **Conclusion**: Based on the analysis, the correct answer to the question is Morphalexis, as it specifically describes the modification of existing cells into different organs during the regeneration process.

### Final Answer:
The correct answer is **Morphalexis**.
