Ribosomes are used. They are required by all Eukaryotic cells.


Ribosomes are mostly protein, combined with some ribosomal RNA (rRNA). Together, they form active 'protein factories'.

Ribosomes are made in the nucleolus of a cell's nucleus.

They are then transported out through the nuclear pores into the cytoplasm.

Eukaryotes have both free-floating ribosomes and embedded ribosomes.
Both types perform the same basic function, translation.
Translation is changing a messenger RNA transcript into a Polypeptide chain.

The Endoplasmic Reticulum ribosomes are for membranous proteins to be made. This structure is called the
'RER' or rough endoplasmic reticulum.
It is an organelle attached physically to the nuclear membrane and which folds over and over into channels.
