Question

which structures are found in each cell type? complete the table.
ribosomes
nucleus
mitochondria
dna

Explanation:

• Ribosomes: Both cell types need ribosomes for protein synthesis. Prokaryotes have 70S ribosomes; eukaryotes have 80S (with some 70S in mitochondria/chloroplasts).
• Nucleus: Prokaryotes lack a membrane - bound nucleus (have a nucleoid); eukaryotes have a true nucleus.
• Mitochondria: Energy - producing organelles. Prokaryotes generate energy through their cell membrane; mitochondria are exclusive to eukaryotes (for most, except some like anaerobic protozoa which have related organelles).
• DNA: Genetic material. Prokaryotic DNA is circular and in the nucleoid; eukaryotic DNA is linear and in the nucleus (plus some in mitochondria/chloroplasts).

Answer:

Ribosomes: Prokaryotic cells (✔️), Eukaryotic cells (✔️)
Nucleus: Prokaryotic cells (❌), Eukaryotic cells (✔️)
Mitochondria: Prokaryotic cells (❌), Eukaryotic cells (✔️)
DNA: Prokaryotic cells (✔️), Eukaryotic cells (✔️)
