Organs that are common in embryonic origin and have the same fundamental structure but perform different functions are called

Options

A. Homogenous organs
B. Homologous organs
C. Analogous organs
D. Vestigial organs

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:** The question asks for the term that describes organs that share a common embryonic origin, have the same fundamental structure, but perform different functions.

2. **Identifying Key Terms:**
- **Embryonic Origin:** This refers to organs that develop from the same embryonic tissues.
- **Fundamental Structure:** This indicates that the organs have a similar anatomical structure.
- **Different Functions:** This means that although the organs are similar in structure, they serve different purposes in different organisms.

3. **Analyzing the Options:**
- **Homogeneous Organs:** This term does not exist in biological terminology, so it can be eliminated.
- **Homologous Organs:** These are organs that arise from a common ancestor and have similar structures but may perform different functions. This fits the description given in the question.
- **Analogous Organs:** These organs perform similar functions but have different structures, which does not match the question's criteria.
- **Vestigial Organs:** These are remnants of organs that were functional in ancestors but are now reduced or non-functional, which is not what the question is asking.

4. **Conclusion:** The correct answer is **Homologous Organs** because they meet all the criteria outlined in the question.

**Final Answer:** Homologous organs.
