Question

An elaborate network of filamentous proteinaceous structures which helps in the maintenance of cell shaped is called

• A. Plasmalemma
• B. Cytoskeleton
• C. Endoplasmic reticulum
• D. Thylakoids

Answer 1

Answer: (B)

Cytoskeleton

• 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.
• So, the correct answer is 'Cytoskeleton'.
