Presence of a true nucleus
Circular DNA genome
Lack of ribosomes
2. Which organelle is responsible for ATP production in eukaryotic cells?
Endoplasmic reticulum
Golgi apparatus
Mitochondria
Ribosomes
1. Prokaryotic cells typically reproduce by , while eukaryotic cells divide by mitosis and meiosis.
2. The genetic material of a prokaryotic cell is found in the , which is not enclosed by a membrane.
