Write "True" or "False".
Sarcomere is covering of striated muscle fibre.

Answer

To determine whether the statement "Sarcomere is covering of striated muscle fibre" is true or false, we can follow these steps:

1. **Understand the Definition of Sarcomere**: A sarcomere is the basic contractile unit of striated muscle fibers. It is the segment between two Z-lines and is made up of actin and myosin filaments.

2. **Identify the Function of Sarcomere**: The primary function of the sarcomere is to facilitate muscle contraction through the sliding filament mechanism, where actin and myosin filaments slide past each other.

3. **Identify the Covering of Muscle Fibers**: The covering of striated muscle fibers is known as the sarcolemma. The sarcolemma is the cell membrane that encloses the muscle fiber.

4. **Compare Sarcomere and Sarcolemma**: Since the sarcomere is a structural and functional unit within the muscle fiber, and the sarcolemma is the outer covering of the muscle fiber, it is clear that the two are distinct entities.

5. **Conclude the Statement**: Based on the definitions and functions, the statement that "Sarcomere is covering of striated muscle fibre" is incorrect.

Final Answer: **False**
