Root Explanation

Cytoskeleton → It is formed from "cyto-" (from Greek "kytos", meaning cell) and "skeleton" (from Greek "skeletos", meaning dried or withered body). The word "cytoskeleton" refers to the structural framework within a cell that provides shape and support, akin to a skeleton in a body.

Memory Tip

Think of 'cyto-' meaning 'cell' and 'skeleton' as the structure that supports it — this helps you remember that a cytoskeleton is the framework that gives shape to a cell.
