Detailed explanation-1: -Prokaryotes lack an organized nucleus and other membrane-bound organelles.
Detailed explanation-2: -Which of the following is not a characteristic of prokaryotes? Explanation: Prokaryotes do not have membrane-bound organelles, such as the nucleus or mitochondria.
Detailed explanation-3: -Nucleus and nuclear membrane are not present but it consists of nucleoid region. Membrane-bound organelles (like Golgi complex, mitochondria, chloroplast etc.) are absent.
Detailed explanation-4: -They are small in size 0.1 mm to 10 mm. They do not possess membrane-bound organelles. They have single circular DNA as genetic material and plasmid. They possess mesosomes for respiration. Some are autotrophic and some are saprotrophic. 05-Sept-2022
Detailed explanation-5: -Membrane bound cell organelles such as Mitochondria, Golgi apparatus, Chloroplasts are absent. A membrane bound well defined nucleus is absent.
