Ribosomes are pear or heart shaped cell organells.These are non-membrane bound.These sre the smallest cell organells.

The ribosomes are described by Palade.
In eukaryotes,ribosomes are either free in the cytoplasm or attached to Endoplasmic Reticulum by Ribophorins.(glycoproteins)

Ribosomes are involved in protein synthesis .During protein synthesis,many ribosomes are attached to the messenger RNA molecule forming Polysomes or Polyribosomes or Ergosomes.

Ribosomes are the sites for protein synthesis.Ribosomes are called Protein factories of a cell.
