Detailed explanation-1: -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-2: -The nucleolus is a ribosome production factory, designed to fulfill the need for large-scale production of rRNAs and assembly of the ribosomal subunits.

Detailed explanation-3: -Explanation : Nucleolus is a darkly pigmented portion of nucleus . It produces rRNA which moves from there to cytoplasm and join with proteins to form ribosomes. So it concludes that nucleolus is the portion of cell which forms ribosomes.

Detailed explanation-4: -An area inside the nucleus of a cell that is made up of RNA and proteins and is where ribosomes are made.

Detailed explanation-5: -The primary function of the nucleolus is in facilitating ribosome biogenesis, through the processing and assembly of rRNA into preribosomal particles.
