Answer:The cells that produce hair contain a lot of ROUGH ENDOPLASMIC RETICULUM , while the cells that produce the oils that coat the hair contain a lot of SMOOTH ENDOPLASMIC RETICULUM.
Explanation: ROUGH ENDOPLASMIC RETICULUM or RER is a cisternae organelle that have two faces: the cytosolic face and the nucleus face. The cytosolic face is studded with ribosomes that are responsible for synthesizing proteins, a process known as translation. In the cells that produce hair, keratinocytes, the main protein synthesized is keratin.
SMOOTH ENDOPLASMIC RETICULUM is an organelle that lacks ribosomes and the function is related to lipid synthesis, different case that proteins synthesis. Specialized cells located in the SER (smooth endoplasmic reticulum) produces the oils that coat the hair called sebum to lubricate the hair. These cells secrete the sebum in an holocrine way. The composition of the sebum is made of triglycerides, wax esters, squalene.
