Organelles that are not made of membranes include ribosomes, the cytoskeleton, and centrioles. Ribosomes are composed of ribosomal RNA and proteins and are responsible for protein synthesis. The cytoskeleton provides structural support and aids in cell movement, while centrioles play a role in cell division. Unlike membrane-bound organelles, these structures are more akin to complex protein assemblies.
