The Correct Option is C
Solution and Explanation
The cytoskeleton is a system that consists of filaments or fibres with an interlinking network of protein filaments. These are present in the cytoplasm of eukaryotic cells. Cytoskeleton supports and maintains the shape of cells and helps in their division too. The cytoskeleton consists of three types of filaments i.e., actin filaments, microtubules, and intermediate filaments.
- Actin filaments: These are the smallest filaments and are made up of actin protein. These filaments help determine the shape of the cell and also help in movement of the cell.
- Microtubules: These filaments are the largest and are made up of tubulin proteins. Microtubules play an important role in movement of daughter chromosomes to form new daughter cells in mitosis.
- Intermediate filaments: These filaments are mid-sized and made from several subunit proteins. These filaments are very stable structures and their function is to place the nucleus within the cell and provide cell with elastic properties.
It can be thus concluded that cytoskeleton are made up of filaments that are proteinaceous. Therefore, Option C is the correct answer.

Cell: The Unit of Life
- A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
- It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
