Question

A component of cytoskeleton is

• A. Microtubule
• B. Bone
• C. Chitin
• D. Cartilage

Answer 1

The correct option is A Microtubule

• The eukaryotic cell is composed of a network of protein fibres that is known as the cytoskeleton.
  
• It is responsible for the movement of organelles around the cytoplasm (organelles are attached to the cytoskeleton).
  
• This network of proteins consists of protein microfilaments, intermediate filaments, and microtubules.
  
• Microtubule provides structure and shape to the cytoplasm of cells (eukaryotic cell, few bacteria).
  
• It is mainly made up of the protein tubulin.
• So, the correct answer is 'Microtubule'.
