Cytoskeleton is an example of which type of organelle?

The cytoskeleton is classified as a non-membranous organelle because it does not have a surrounding membrane, unlike membranous organelles such as the nucleus, mitochondria, and endoplasmic reticulum. Instead, the cytoskeleton consists of a dynamic network of protein filaments and tubules that provide structural support, facilitate intracellular transport, and enable cell movement and division.

This structural framework is crucial for maintaining the shape of the cell, anchoring organelles in place, and assisting in cellular processes like mitosis and cytokinesis by organizing the mitotic spindle. Non-membranous organelles, such as ribosomes and the cytoskeleton, are vital for cellular function, even though they lack the lipid bilayer that characterizes membranous organelles. Understanding the distinction between these types of organelles is important in the context of cell biology and how various cellular components work together to maintain cellular homeostasis and function.
