cytoskeleton
The cytoskeleton is a network of protein fibers inside cells that provides structure and shape, much like a scaffolding in a building. It helps maintain the cell's integrity, enables movement, and assists in transporting materials within the cell. Composed of three main components—microfilaments, intermediate filaments, and microtubules—each plays a specific role. For example, microtubules act like tracks for transporting organelles. Overall, the cytoskeleton is essential for various cellular functions, including division, communication, and adaptability to changes in the environment.

The cytoskeleton is a network of fibers within cells that provides structure, support, and shape. Think of it as the scaffolding that holds up a building. It consists of three main types of fibers: microtubules, actin filaments, and intermediate filaments. These fibers help the cell maintain its shape, facilitate movement, and transport materials within the cell. Additionally, the cytoskeleton plays a crucial role during cell division, ensuring that genetic material is properly distributed to daughter cells. In essence, it is vital for the cell's overall organization and functionality.
