each of the following is an example of a nonmembranous organelle except

○ cilia.
○ centrioles.
○ lysosomes.
○ ribosomes.
○ cytoskeleton.

Explanation:

To solve this, we recall the difference between membranous and nonmembranous organelles. Nonmembranous organelles lack a membrane, while membranous ones have a membrane.

• Cilia: Nonmembranous (made of microtubules).
• Centrioles: Nonmembranous (composed of microtubules).
• Lysosomes: Membranous (have a single membrane, contain digestive enzymes).
• Ribosomes: Nonmembranous (composed of RNA and protein).
• Cytoskeleton: Nonmembranous (network of protein filaments).

So lysosomes are the exception as they are membranous, while the others are nonmembranous.

Answer:

C. lysosomes
