Detailed explanation-1: -Ribosomes are cell organelles that function in the synthesis of proteins. They are present on the surface of rough endoplasmic reticulum. They produce proteins from amino acids by a process called protein synthesis. Therefore, ribosomes are called protein factories as they synthesize proteins.

Detailed explanation-2: -Nucleolus: the ribosome factory.

Detailed explanation-3: -What looks like a jumble of rubber bands and twisty ties is the ribosome, the cellular protein factory. The ribosome is made up of proteins and strands of RNA, a chemical relative of DNA. It has two interlocked parts that behave as a single molecular machine to assemble all of the cell’s protein molecules.

Detailed explanation-4: -The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells.

Detailed explanation-5: -If DNA is the blueprint, then ribosomes are the masons-they build the protein using amino acids as the ‘bricks’. To build proteins, the two ribosomal subunits, small and large, assemble together to form the complete ribosome. It has binding sites for mRNA and transfer RNA (tRNA) molecules.
