Which of the following cell structures is mainly responsible for providing support and maintaining the shape of eukaryotic cells?
Cytoskeleton
The cytoskeleton is a dense network of protein filaments (microfilaments, intermediate filaments and microtubules) inside the eukaryotic cell.
It gives the cell mechanical support, holds organelles in place and maintains the overall cell shape.
The nucleus stores DNA, ribosomes make proteins and the endoplasmic reticulum synthesises lipids and proteins; none of these is primarily a shape-support structure.
Hence, the answer is Cytoskeleton.
