Any cell that is currently manufacturing proteins. The bumps are ribosomes - protein factories - having attached to the ER after latching onto the mRNA.
Ribosomes
They are ribosomes which translates messenger RNA into proteins
Ribosomes are small "bumps" located on the rough endoplasmic reticulum.
The small bumps located on portions of the endoplasmic reticulum are ribosomes. Ribosomes are responsible for protein synthesis within the cell. The endoplasmic reticulum with ribosomes attached is called rough endoplasmic reticulum, and it plays a crucial role in protein production and transport within the cell.

The bumps on the rough endoplasmic reticulum are ribosomes, which are responsible for protein synthesis in the cell. Ribosomes on the rough ER synthesize proteins that are either inserted into the ER membrane or exported from the cell.
Ribosomes would be the simple answer, but they only bind to the endoplasmic reticulum once it begins to synthesize a protein. Other bumpy structures you may encounter on the endoplasmic reticulum are proteins and vesicles.
protein
Used for moving nutrients and things throughout the cell. Like a conveyer belt.
Ribosomes.
The rough endoplasmic reticulum is characterized by ribosomes on the surface. When viewed (using an electron microscope) they appear as black dots. Ribosomes are responsible for translating mRNA into protein and use tRNA to obtain the amino acids needed for the process. Ribosomes are actually composed of two subunits (30S and 50S in humans).
