EVERYDAY SCIENCE

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: -Prokaryotes are small and lack membrane-bound nuclei Their genetic material isn’t stored within a membrane-bound nucleus. Instead, it is stored in a nucleoid that floats in the cell’s cytoplasm.

Detailed explanation-3: -The nucleus is where most of the genetic material (genes, DNA) is housed. It is enclosed by a two-layered nuclear membrane that is perforated by pores that regulate the passage of molecules and particles. Within the nucleus is the nucleolus that makes the ribosomes.

Detailed explanation-4: -The nucleus is where cells store their DNA, which is the genetic material. Prokaryotes do not have a nucleus. Instead, their DNA floats around inside the cell. Eukaryotes are single-celled (unicellular) organisms.

Detailed explanation-5: -The genetic material in prokaryotes is generally contained within a central region of the cell called nucleoid that is not surrounded by the nuclear membrane. Both prokaryotic and eukaryotic cells are surrounded by a plasma membrane (cell membrane).
