Verified step by step guidance

Understand the function of ribosomes: Ribosomes are cellular structures responsible for protein synthesis. They translate messenger RNA (mRNA) into polypeptide chains, which then fold into functional proteins.

Identify the location of ribosomes: Ribosomes are found in both prokaryotic and eukaryotic cells. In eukaryotic cells, they can be free-floating in the cytoplasm or attached to the endoplasmic reticulum, forming rough ER. They are not confined to the nucleus.

Clarify the nature of ribosomes: Ribosomes are not membrane-bound organelles. They are composed of ribosomal RNA (rRNA) and proteins, forming two subunits that come together during protein synthesis.

Differentiate ribosome functions: Ribosomes are not involved in lipid synthesis. Lipid synthesis primarily occurs in the smooth endoplasmic reticulum and other specialized organelles.

Conclude with the correct statement: Based on the above clarifications, the statement 'Ribosomes are responsible for protein synthesis' is true, as it accurately describes the primary function of ribosomes in the cell.
