Which of the following components is found in both prokaryotic and eukaryotic cells?

In both prokaryotic and eukaryotic cells, a common fundamental component is the presence of organelles, albeit with notable differences. Prokaryotic cells, such as bacteria, do not have membrane-bound organelles, but they contain ribosomes, which are considered a type of organelle involved in protein synthesis. Eukaryotic cells, such as those in plants and animals, have a variety of membrane-bound organelles, including the nucleus, endoplasmic reticulum, and others, which facilitate complex cellular functions.

The distinction lies in the definition of organelles; while prokaryotes have fewer and simpler structures, they still possess essential components necessary for life. The absence of a nucleus in prokaryotic cells does not negate the presence of organelles overall.

In contrast to the other options, such as multiple chromosomes, mitochondria, and chloroplasts, these components are specific to certain types of eukaryotic cells or are completely absent from prokaryotes. For example, multiple chromosomes are primarily found in eukaryotic cells, mitochondria are membrane-bound organelles unique to eukaryotic organisms, and chloroplasts are present only in the plant cells and some protists. Thus
