AnsweR:
Rough endoplasmic reticulum.
Explanation:
The endoplasmic reticulum is a member of the endomembrane system and is present as a continuation of the nuclear membrane. They are divided into the rough endoplasmic reticulum and smooth endoplasmic reticulum.
Rough endoplasmic reticulum has ribosomes on its surface and is responsible for the synthesis of secretory proteins. Smooth endoplasmic reticulum synthesize lipids.
Therefore cells that intensely biosynthesize secretory proteins like neurons, white blood cells have a greater amount of rough endoplasmic reticulum than another cell of the body.
