Answer:
Ribosomes are the machinery of protein synthesis in the cell. They are associated with different organelle of the cell. They are also found free-floating in the cytoplasm of the cell.
The organelle which ribosomes interact are plasma membrane in prokaryotes and endoplasmic reticulum(ER) in eukaryotic cell. Ribosomes are present on the surface of the ER and helps in protein synthesis in the ER. In prokaryotes, there is no ER so it is associated with plasma membrane and perform protein synthesis.
The specialized function of ribosome is to perform protein synthesis and these proteins are necessary for cell because protein are important to make enzymes that regulate the metabolism of the cell. So if protein synthesis stops cell will not able to perform important metabolic activities to survive and it will die.
Having a large number of ribosomes benefits cells because it fastens the protein synthesis process in the cell. So large amount of protein can be produced in less time.
The gel like substance inside the cell but outside of the nucleus is known as <em>Cytoplasm </em>
