Organelles

Ribosomes are the organelles responsible for protein synthesis.

In the plant cell model that Mario presented, a horse chestnut took the place of the nucleus, a handful of plasticine was the cytoplasm, the organelles were represented by lentils and other beans, small bits of green pipe cleaner served as chloroplasts, and the plastic bottle that held everything was the cell membrane, surrounded by a thick papier-mâché coat for the cell wall.

Mitochondria evolved from independent organisms into organelles.

Prokaryotes do not have organelles such as mitochondria or chloroplasts; eukaryotes have a variety of organelles, some of which are separated from the cytoplasm by membranes.

In their unaltered state, macrophages try to fix damaged arteries by cleaning up cellular waste, including misshapen proteins, excess fat, and dysfunctional cellular structures called organelles.
