Small bumps located on portions of the endoplasmic reticulum

Ribosomes are small organelles which are sphere- shaped. They are usually found freely in the cytoplasm and also attached to the endoplasmic reticulum. When attached to the endoplasmic reticulum (ER), they make such ER rough endoplasmic reticulum. Ribosomes comprises of RNA and protein and functions as a site for the synthesis of proteins. Ribosomes can be found in both prokaryotic cells and eukaryotic cells, all cells need ribosomes because all cells require it for the synthesis of protein.

Answer:

Ribosomes

Explanation:

The small bumps located on portions of the endoplasmic reticulum are ribosomes.

There are two types of endoplasmic reticulum, namely:

Smooth endoplamic reticulum
Rough endoplasmic reticulum

The smooth endoplamic reticulum is ribosome-free while the rough endoplasmic reticulum appears rough when viewed under the microscope due to the attachment o ribosomes.

The ribosomes are small circular organs and are utilized in protein synthesis. Hence, the rough endoplasmic reticulum functions in the production of protein in the cell.
