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: -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-3: -The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

Detailed explanation-4: -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.

Detailed explanation-5: -Lysosome: Lysosome is large, 0.1-1.2 µm in size. Ribosome: Ribosome is comparatively small, 20-30 nm in size.
