Cytoskeleton of cell is made up of

Options

A. Lysosome & vacoules & ribiosomes
B. microtubules
C. microfilaments and microtubules
D. all of the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Cytoskeleton**: The cytoskeleton is a network of protein filaments and tubules that provide structural support to the cell. It plays a crucial role in maintaining the shape of the cell and facilitating movement.

2. **Components of the Cytoskeleton**: The cytoskeleton is primarily made up of three types of proteinaceous filaments:
- **Microtubules**: These are hollow tubes made of tubulin proteins. They are involved in maintaining cell shape, enabling cell motility (like cilia and flagella), and facilitating intracellular transport.
- **Microfilaments**: Also known as actin filaments, these are thin strands composed of actin proteins. They are important for cell movement, shape, and muscle contraction.
- **Intermediate Filaments**: These filaments provide mechanical support and help maintain the integrity of the cell structure. They are made of various proteins depending on the cell type.

3. **Functions of the Cytoskeleton**: The cytoskeleton supports the cell, helps in motility, and maintains the cell's shape. It is essential for various cellular processes, including division and intracellular transport.

4. **Conclusion**: Therefore, the cytoskeleton of the cell is made up of microtubules, microfilaments (actin), and intermediate filaments.

**Final Answer**: The cytoskeleton of the cell is made up of microtubules, microfilaments, and intermediate filaments.
