ANATOMY

Detailed explanation-1: -The ER also contains domains that contact the plasma membrane (PM) and other organelles including the Golgi, endosomes, mitochondria, lipid droplets, and peroxisomes.

Detailed explanation-2: -The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

Detailed explanation-3: -Organelles : Example Question #3 Explanation: Ribosomes are composed of a unique type of RNA, rRNA, and are located within the cytoplasm of the cell and on the surface of the rough endoplasmic reticulum.

Detailed explanation-4: -The process of protein synthesis occurs in ribosomes. Ribosomes are either floating freely in the cytoplasm or found attached to the endoplasmic reticulum.
