Typical axons almost never contain ribosomes, except some in the initial segment.

In 1967 it was discovered that mitochondria contained ribosomes.

Rhizopus arrhizus spores contain ribosomes as a spore ultrastructure.

The schizonts also contain numerous cytomers also with trilaminar membranes and containing multiple ribosomes.

Like mitochondria, chloroplasts also contain their own DNA and ribosomes.

The teloplasm contains the nucleus, ribosomes, mitochondria, and other subcellular organelles.

The mitochondrial matrix also contains the mitochondria's DNA and ribosomes.

Dendrites contain granular endoplasmic reticulum or ribosomes, with diminishing amounts with distance from the cell body.

The cytoplasm contains numerous large ribosomes.

In this experiment, using a ribosome binding assay, various combinations of mRNA were passed through a filter which contained ribosomes.
