Detailed explanation-2: -Which structure could be found in a prokaryotic cell? Explanation: Prokaryotic cells differ from eukaryotic cells in that they lack any membrane-bound organelles, including a nucleus. Instead, prokaryotic cells simply have an outer plasma membrane, DNA nucleoid structure, and ribosomes.

Detailed explanation-3: -Ribosomes are the smallest cell organelles which can be seen only through an electron microscope. They are found in both prokaryotic as well as eukaryotic cells. Ribosomes are dense, round bodies which occur freely in the cytoplasm and may remain attached to the surface of the endoplasmic reticulum.
