NEET BIOLOGY

Detailed explanation-1: -The organelle that acts as a supporting skeletal framework of the cell is the endoplasmic reticulum. The endoplasmic reticulum provides additional mechanical support to the cell by dividing the fluid content of the cell into compartments. That is why it is considered one of the elements of the cytoskeleton.

Detailed explanation-2: -The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments.

Detailed explanation-3: -The cytoskeleton provides a structural framework for the cell, serving as a scaffold that determines cell shape and the general organization of the cytoplasm. In addition to playing this structural role, the cytoskeleton is responsible for cell movements.
