Ribosomes

Explanation:

Ribosomes are structures in charge of manufacturing proteins, every cell needs to have proteins. They can be found in prokaryotic and eukaryotic cells. On the other hand, chloroplasts, mitochondria and nuclear envelope are not found in prokaryotic cells.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.
