Which organelle synthesises lipids?

Explanation:
Lipids are synthesized in the smooth endoplasmic reticulum because it contains enzymes specialized for lipid formation and it lacks ribosomes, giving it a "smooth" surface. This contrasts with the rough endoplasmic reticulum, which is studded with ribosomes and specializes in protein synthesis. The Golgi apparatus modifies and packages lipids and proteins after they’re made, rather than synthesizing them. The nucleus stores genetic material and is not involved in lipid production. So the smooth endoplasmic reticulum is the organelle responsible for lipid synthesis.
