Solution

The correct option is C Microfilaments
  • Cyclosis is caused by the activity of microfilaments.
  • Microfilaments (actin filaments) are the filaments that are present in the cytoplasm of the cells (eukaryotic) and it forms a part of the cytoskeleton.
  • It is made up of polymers of actin.
  • These microfilaments cause cytoplasmic streaming or protoplasmic streaming which is the movement of the cytoplasm within a cell.
  • When one of the protein is fixed on a microfilament then, the motor proteins can move organelles and molecules within the cytoplasm.
  • So, the correct answer is 'Microfilaments'.
