Cell wall structure of a cell of unknown origin was studied and was found to contain polysaccharide chain linked with short chains of amino acid. What do you think it can be?
Correct answer: A. Bacteria
- A. Bacteria
- B. Fungi
- C. Algae
- D. Plants
Explanation
The correct answer is Bacteria. The question describes a cell wall structure featuring polysaccharide chains linked by short chains of amino acids, indicative of peptidoglycan. This is a unique feature of bacterial cell walls, providing them with necessary structural integrity. In contrast, fungal cell walls are made of chitin, algal walls of cellulose or other substances, and plant walls of cellulose and hemicellulose, all lacking the peptidoglycan structure.
