Which of these cell organelles found exclusively in eukaryotes is not membrane bound?

Options

  1. ARibosomes
  2. BCilia
  3. CNucleolus
  4. DLysosome

Correct answer

C. Nucleolus

Step-by-step solution

The nucleolus, ribosomes, and centrioles are non-membrane bound cell organelles. Ribosomes are found in both prokaryotes and eukaryotes. The entire endomembranous system (ER, Golgi body, lysosome, vacuole), peroxisomes, cilia, flagella have a single membrane surrounding them. Mitochondria and nucleus are surrounded by two membranes.
