select the structure below that is not found in both prokaryotes and eukaryotes
No structures shown.
To determine the structure that is not found in both prokaryotes and eukaryotes, we need to compare the characteristics of these two types of cells. Let's start with understanding the differences between prokaryotes and eukaryotes.
Prokaryotes are single-celled organisms that lack a nucleus and other membrane-bound organelles. They are simpler in structure and are represented by bacteria and archaea.
Eukaryotes, on the other hand, are more complex organisms that have a nucleus and various membrane-bound organelles. They include all multicellular organisms like plants, animals, fungi, and protists.
Now, let's look at the structures commonly found in both prokaryotes and eukaryotes, such as cell membranes, ribosomes, cytoplasm, and genetic material (DNA). These components are present in both cell types.
To find the structure that is not common to both, we need to identify a structure that is found only in either prokaryotes or eukaryotes. One such structure is the nucleus.
The nucleus is a membrane-bound organelle that contains the cell's DNA and is present only in eukaryotic cells. Prokaryotic cells lack a defined nucleus; instead, their DNA floats freely in the cytoplasm.
Therefore, the structure that is not found in both prokaryotes and eukaryotes is the nucleus.
