Detailed explanation-1: -So, the correct option is ‘False’.
Detailed explanation-2: -Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus. The chromosome, a single, continuous strand of DNA, is localized, but not contained, in a region of the cell called the nucleoid. All the other cellular components are scattered throughout the cytoplasm.
Detailed explanation-3: -Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.
Detailed explanation-4: -Answer and Explanation: The statement “Bacterial cells have a cell wall made of cellulose” is false.
Detailed explanation-5: -Eukaryotes (meaning ‘true nuclei” where “karyote” is derived from the ancient Greek for “kernel") include fungi, protozoa, eukaryotic algae, and of course plants and animals including ourselves. Eukaryotic cells have a nucleus containing chromosomal DNA bounded by membranes.
