Detailed explanation-1: -Ribosomes are the smallest organelle present in the cell irrespective of the type of the cell. These are a complex of ribosomal RNA molecules and proteins that is responsible to carry out protein synthesis. Ribosomes are spheroidal dense particles ranging from 20-30 nm in diameter.

Detailed explanation-2: -Proteins are assembled at organelles called ribosomes.

Detailed explanation-3: -Ribosomes are the smallest cell organelles. They are not membrane bound and have important role in synthesis of proteins. They are found in both prokaryotic and eukaryotic cells.

Detailed explanation-4: -The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes.

Detailed explanation-5: -The smallest organelle is ribosome. The diameter of ribosome is about 20 nm. It is the site for the manufacture of proteins within the cell.
