Detailed explanation-1: -Prokaryotic cells, such as bacteria, have a free-floating chromosome that is usually circular and is not enclosed in a nuclear membrane . Instead, the DNA simply exists in a region of the cell called the nucleoid. Prokaryotic cells only have a small range of organelles, generally only a plasma membrane and ribosomes.

Detailed explanation-2: -The prokaryotic cell’s genetic material is located in an area with an irregular form called a nucleoid, which is a nucleus-like structure. Prokaryotic cells lack a true nucleus. The nucleus is devoid of the nuclear membrane.

Detailed explanation-3: -Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Detailed explanation-4: -These cells do not have membrane-bound cell organelles such as Golgi bodies, mitochondria, lysosomes, ER, peroxisomes, etc. Prokaryotes do not have a nucleus, so hence do not have a nucleolus.

Detailed explanation-5: -Does Bacteria Have a Nucleus? Bacteria cells are prokaryotic cells; therefore, they lack a nucleus. In eukaryotic cells, the nucleus is where the DNA is housed. However, in bacteria cells, the DNA or genetic information is found floating freely in the cytoplasm of the cell.
