The correct Answer is:
To solve the question, we need to identify the type of symmetry described in the statement: "When any plane passing through the central axis of the body divides the organism into two identical halves." Let's break this down step by step. ### Step-by-Step Solution: 1. **Understanding Symmetry**: - Symmetry refers to the property of an organism that allows it to be divided into two equal halves. This can occur in various ways depending on the organism's structure. 2. **Analyzing the Options**: - **Radial Symmetry**: This type of symmetry allows an organism to be divided into two identical halves by any plane that passes through the central axis. Organisms like jellyfish exhibit this type of symmetry. - **Bilateral Symmetry**: This type of symmetry means that an organism can only be divided into two identical halves by one specific plane (usually down the middle). Humans and many animals exhibit bilateral symmetry. - **Central Symmetry**: This term is not commonly used in biological contexts and generally refers to symmetry around a central point, which does not fit our description. - **Axial Symmetry**: Similar to central symmetry, axial symmetry refers to symmetry around an axis and does not apply to the definition provided in the question. 3. **Identifying the Correct Answer**: - Given the definitions, the only type of symmetry that allows for division into identical halves through any plane passing through the central axis is **Radial Symmetry**. 4. **Conclusion**: - Therefore, the correct answer to the question is **Radial Symmetry**. ### Final Answer: The correct answer is **Radial Symmetry**.
