The correct Answer is:
To answer the question, "The central core of cilium (or flagellum) is known as," we need to identify the correct term that describes this structure. ### Step-by-Step Solution: 1. **Understanding Cilia and Flagella**: - Cilia and flagella are hair-like structures that protrude from the surface of some eukaryotic cells. They are involved in movement and sensory functions. 2. **Identifying the Central Core**: - The central core of cilia and flagella is known as the "axoneme." This structure is crucial for the movement of these appendages. 3. **Composition of the Axoneme**: - The axoneme is composed of microtubules arranged in a specific pattern. The typical arrangement is known as the "9 + 2" structure, which consists of nine pairs of microtubules arranged in a circle surrounding two central microtubules. 4. **Evaluating the Options**: - **Option 1: Axoneme** - This is the correct answer as it refers to the central core of cilia and flagella. - **Option 2: Microtubule** - This is incorrect as it refers to the individual components that make up the axoneme. - **Option 3: Duplet** - This is also incorrect; it does not refer to any structure in cilia or flagella. - **Option 4: Triplet** - This is incorrect as well; while triplet arrangements are found in centrioles, they do not describe the axoneme. 5. **Conclusion**: - The correct answer to the question is **"axoneme."** ### Final Answer: The central core of cilium (or flagellum) is known as the **axoneme**.
