Detailed explanation-1: -Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

Detailed explanation-2: -Ribosomes are the non-membranous cell organelles observed in both prokaryotic and eukaryotic cells as well.

Detailed explanation-3: -Ribosomes are different from other organelles because they have no membrane around them that separates them from other organelles.

Detailed explanation-4: -Complete answer: Ribosomes are non-membrane bound organelles found in all living cells i.e. both in eukaryotic as well as prokaryotic.
