<u>Removing waste from cel</u>l is NOT a function of the cytoskeleton
Answer: Option B
<u>Explanation:</u>
The cytoskeleton provides the shape and support to the cell. It has a rigid wall to give a shape and structure for the cell. It helps in the mobility of the cell and aids in the cell movement.
It also helps in transporting the communication signals from one cell to another. The cytoskeleton is made up of micro tubules, micro filaments and intermediate filaments. It also helps to move the nutrients within the cells. But it doesn’t help the removal of waste from the cell.
