JC has created a Venn diagram to help him remember which cell structures are present only in prokaryotes, only in eukaryotes, or in both. Complete JC's diagram with the cell structures shown below.

nucleus
DNA
cell membrane
mitochondria
ribosomes
cytoplasm

Here is how JC's Venn diagram can be completed:

Prokaryotes:
- DNA
- Cell membrane
- Ribosomes
- Cytoplasm

Eukaryotes:
- Nucleus
- DNA
- Cell membrane
- Mitochondria
- Ribosomes
- Cytoplasm

Both:
- DNA
- Cell membrane
- Ribosomes
- Cytoplasm
