AIIMS 2018 Botany Cell Organelles MCQ Question

Smooth endoplasmic reticulum (SER) is responsible for the synthesis of lipids, including phospholipids and cholesterol, which are essential for cell membrane formation. Additionally, it plays a crucial role in detoxifying drugs and harmful metabolic byproducts, particularly in liver cells, by modifying these substances to make them more water-soluble for excretion. Other options are not provided, but it is important to note that organelles like rough endoplasmic reticulum and ribosomes primarily focus on protein synthesis, not lipid synthesis or detoxification. Understanding the specific functions of organelles helps clarify their roles in cellular metabolism and homeostasis.
