Verified step by step guidance

Identify the organelle in question: the smooth endoplasmic reticulum (SER).

Understand the structure of the smooth endoplasmic reticulum: it lacks ribosomes on its surface, unlike the rough endoplasmic reticulum.

Recall the primary functions of the smooth endoplasmic reticulum: it is involved in the synthesis of lipids, metabolism of carbohydrates, detoxification of drugs and poisons, and storage of calcium ions.

Differentiate the functions of the smooth endoplasmic reticulum from other cellular processes: DNA replication occurs in the nucleus, photosynthesis occurs in chloroplasts (in plant cells), and protein synthesis primarily occurs in the rough endoplasmic reticulum and ribosomes.

Conclude that the primary function of the smooth endoplasmic reticulum is the synthesis of lipids, as it is not directly involved in DNA replication, photosynthesis, or protein synthesis.
