Guida verificata passo dopo passo1
Understand the basic differences between prokaryotic and eukaryotic cells. Prokaryotic cells are simpler and do not have membrane-bound organelles, while eukaryotic cells have complex structures with membrane-bound organelles.
Identify the organelles listed in the problem: Chloroplasts, Nucleus, Mitochondria, and Ribosomes.
Recall that chloroplasts, the nucleus, and mitochondria are membrane-bound organelles, which are typically found only in eukaryotic cells.
Recognize that ribosomes are not membrane-bound and are present in both prokaryotic and eukaryotic cells. They are responsible for protein synthesis in all living cells.
Conclude that the organelle present in both prokaryotic and eukaryotic cells is ribosomes, as they are essential for protein synthesis in all cell types.
