Question

which cell structures are seen in prokaryotic and eukaryotic cells?
□ nucleus
□ cell membrane
□ mitochondria
□ dna
□ ribosomes
□ cytoplasm
done

Explanation:

1. Nucleus: Prokaryotic cells lack a nucleus (they have a nucleoid region instead), so this is not in both.
2. Cell membrane: Both prokaryotic and eukaryotic cells have a cell membrane to control the movement of substances in and out of the cell.
3. Mitochondria: Prokaryotic cells do not have mitochondria (they use other means for energy production), so this is not in both.
4. DNA: Both prokaryotic and eukaryotic cells contain DNA as their genetic material (prokaryotes have circular DNA, eukaryotes have linear DNA in the nucleus and other organelles).
5. Ribosomes: Both types of cells have ribosomes, which are involved in protein synthesis (prokaryotic ribosomes are smaller, 70S, and eukaryotic are 80S, but they are present in both).
6. Cytoplasm: Both prokaryotic and eukaryotic cells have cytoplasm, the gel - like substance within the cell where many cellular processes occur.

Answer:

• cell membrane
• DNA
• ribosomes
• cytoplasm
