Prokaryotic and eukaryotic cells generally have which of the following features in common?
Correct answer: B. Presence of ribosomes
- A. A membrane-bound nucleus
- B. Presence of ribosomes
- C. A cell wall made up of cellulose
- D. Linear genome
Explanation
Both prokaryotic and eukaryotic cells share the presence of ribosomes, which are crucial for protein synthesis. Although eukaryotic cells have additional complex structures like a membrane-bound nucleus, this is not present in prokaryotic cells. Cell walls made of cellulose are characteristic of plant cells (a type of eukaryotic cell), while most prokaryotic cell walls are composed of peptidoglycan. Lastly, eukaryotic cells contain linear chromosomes, whereas prokaryotic cells have circular DNA.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
