The Endoplasmic reticulum is the organelles that is involved in the synthesis of oils.
<u>Explanation:</u>
The endoplasmic reticulum is of 2 types that is the ''smooth endoplasmic reticulum'' and the ''rough endoplasmic reticulum''. The rough endoplasmic reticulum is lined with ribosomes whereas the smooth endoplasmic reticulum is plain.
Since ribosomes are present the rough endoplasmic reticulum is involved in protein synthesis whereas the smooth endoplasmic reticulum is involved in the production of oils or lipids that are required for the cell.
