Question

What are the functions of the cytoskeleton?

1) Cell shape and support
2) Cell movement
3) Cell division
4) Cell communication

Answer 1

The cytoskeleton has functions related to cell shape and support, cell movement, cell division, and cell communication.

Step-by-step explanation:

The cytoskeleton, a group of fibrous proteins, performs several important functions within cells. These functions include:

1. Cell shape and support: The cytoskeleton provides structural integrity and helps maintain the shape of the cell.
2. Cell movement: Components of the cytoskeleton, such as microfilaments and microtubules, enable cell motility by forming cytoplasmic extensions and facilitating the movement of organelles and vesicles.
3. Cell division: Microtubules of the cytoskeleton are involved in separating replicated chromosomes during cell division.
4. Cell communication: Certain components of the cytoskeleton are involved in cell-to-cell or cell-to-matrix junctions, enabling communication between cells.
