ANATOMY

Detailed explanation-1: -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-2: -As mentioned above, ribosomes are the molecular machines responsible for protein synthesis. A ribosome is made out of RNA and proteins, and each ribosome consists of two separate RNA-protein complexes, known as the small and large subunits.

Detailed explanation-3: -Nucleolus: the ribosome factory.

Detailed explanation-4: -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-5: -Ribosomes are the protein factories of the cell. Composed of two subunits, they can be found floating freely in the cell’s cytoplasm or embedded within the endoplasmic reticulum.
