Eukaryotes can share which of the following structures with prokaryotes?
Correct answer: A. Cell wall
- A. Cell wall
- B. Golgi
- C. Mitochondria
- D. Nucleoid
Explanation
The cell walls of prokaryotes have a unique macromolecule called peptidoglycan. Its amount varies in different types of bacteria. It is composed of a framework of long glycan chains cross-linked with peptide fragments. The intact cell wall also contains chemical constituents such as sugar molecules, teichoic acid, lipoproteins, and lipopolysaccharides, which are linked to peptidoglycan. The most distinctive feature of the prokaryotic cell is its cell wall, composed of polysaccharide chains bound covalently to shorter chains of amino acids forming peptidoglycan or murein. The entire cell wall is often regarded as a single huge molecule or molecular complex called a sacculus The cell wall of plants is generally made up of cellulose and is differently structured than that of a bacterium.

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.
