Prokaryotic All bacterial cells are prokaryotic. Bacteria are a single-celled microscopic organism. Bacterial cell lacks a membrane-bound nucleus, specialized membrane-bound organelles like mitochondria and lysosomes. Bacteria also lack the plasma membrane. All these features are characteristic of prokaryotic organisms. Prokaryotes also have a single circular DNA chromosome, which is much smaller than DNA in eukaryotes.
DNA is stored in the nucleoid, which is found in the cytoplasm. Eukaryotic cells, on the other hand, contain membrane-bound organelles such as mitochondria, Golgi apparatus, chloroplast, endoplasmic reticulum, and so on. It also includes a nucleus. DNA in eukaryotes is linear, and they are stored as chromosomes in the nucleus. Eukaryotes can be single-celled or multi-celled.
