The correct Answer is:
To answer the question on how cilia differ from flagella, let's analyze the options one by one based on the information provided in the video transcript. ### Step-by-Step Solution: 1. **Understanding Cilia and Flagella**: - Cilia and flagella are both hair-like structures that protrude from the surface of cells and are involved in movement. - Cilia are generally shorter and more numerous than flagella. 2. **Analyzing Option (A)**: "in having small size" - Cilia are indeed smaller in size compared to flagella. This statement is **true**. 3. **Analyzing Option (B)**: "in having non-coordinated movement" - Cilia exhibit coordinated movement, often beating in a wave-like fashion, while flagella typically have a more whip-like motion. Therefore, this statement is **false**. 4. **Analyzing Option (C)**: "in taking part in attachment, feeding and sensation" - Cilia can play roles in attachment, feeding, and sensation, especially in certain epithelial cells (like those in the trachea). This statement is **true**. 5. **Analyzing Option (D)**: "in number of microtubules" - Both cilia and flagella have a similar arrangement of microtubules (typically 9 pairs of microtubules surrounding 2 central microtubules). Hence, this statement is **false**. 6. **Analyzing Option (E)**: "in working like oars" - Cilia do indeed move in a coordinated back-and-forth motion, similar to the action of oars. This statement is **true**. ### Conclusion: Based on the analysis: - The true statements are (A), (C), and (E). - Therefore, the correct answer is **(A), (C), and (E)**.
