GENERAL HISTOLOGY

Detailed explanation-1: -Ribosomes are the cellular structures responsible for protein synthesis. When viewed through an electron microscope, ribosomes appear either as clusters (polyribosomes) or single, tiny dots that float freely in the cytoplasm.

Detailed explanation-2: -The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence.

Detailed explanation-3: -The proteins and nucleic acids that form the ribosome sub-units are made in the nucleolus and exported through nuclear pores into the cytoplasm.

Detailed explanation-4: -Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins.

Detailed explanation-5: -Then there’s the smooth endoplasmic reticulum, which doesn’t have those ribosomes on it. And that smooth endoplasmic reticulum produces other substances needed by the cell. So the endoplasmic reticulum is an organelle that’s really a workhorse in producing proteins and substances needed by the rest of the cell.
