Plasma membrane of ...... is known as sarcolemma.

Options

A. Myofibre
B. Myofibril
C. Muscle
D. Fascicles

Answer

To solve the question "Plasma membrane of ...... is known as sarcolemma," we need to identify which type of cell has its plasma membrane referred to as sarcolemma. Here’s the step-by-step solution:

### Step 1: Understand the Term "Sarcolemma"
- Sarcolemma is a specific term used to describe the plasma membrane of muscle cells. It is important to recognize that this term is not used for all types of cells but is specific to muscle tissue.

### Step 2: Identify the Type of Cells
- The question asks for the type of cell whose plasma membrane is called sarcolemma. In this context, we are looking for muscle cells.

### Step 3: Define Myofiber
- Myofibers are the individual muscle fibers that make up muscle tissue. They are the basic structural and functional units of muscle. The plasma membrane of myofibers is specifically referred to as sarcolemma.

### Step 4: Conclusion
- Based on the information gathered, the correct answer to the question is "myofiber." Therefore, the complete answer is:

**Plasma membrane of myofiber is known as sarcolemma.**
