Detailed explanation-1: -A cell wall made up of peptidoglycan is found in bacteria and not in eukaryotes. Eukaryotic cell wall is made up of cellulose hemicellulose, pectin chitin etc. Thus, is not true for eukaryotic cell.
Detailed explanation-2: -Because protein synthesis is an essential function of all cells, ribosomes are found in practically every cell type of multicellular organisms, as well as in prokaryotes such as bacteria. However, eukaryotic cells that specialize in producing proteins have particularly large numbers of ribosomes.
Detailed explanation-3: -Therefore, the correct option is b. The chromosome similarity of organelles (mitochondria and chloroplast) does not support the endosymbiotic theory and having non-coding DNA.
