Question

Which one provides support to microvilli, membrane rufflings and pseudopodia?

• A. Microfilaments
• B. Desmin and vimentin filaments
• C. Microtubules
• D. Endoplasmic reticulum
  

Answer 1

The correct option is A Microfilaments

• Microfilaments (actin filaments) are a part of the cytoskeleton found in the cytoplasm of a eukaryotic cell.
  
• They are made up of polymers of actin and its main function is to provide support to the cell.
• Its main function includes:

1. to provide shape to the cell.
2. to provide support to the cell protrusions- microvilli, pseudopodia etc.
3. to provide adhesion to cells and matrix.

• Membrane ruffling refers to the formation of a motile cell surface which contains a meshwork of newly polymerized actin filaments (microfilaments).
  
• So, the correct answer is 'Microfilaments'.
