Which cell organelle plays a crucial role in detoxifying many poisons and drugs in a cell?
(a) Golgi apparatus
(b) Lysosomes
(c) Smooth endoplasmic reticulum
(d) Vacuoles
Explanation: The smooth endoplasmic reticulum (SER) plays a crucial role in the detoxification process within cells. It is particularly abundant in liver cells, known as hepatocytes, which are vital for metabolizing various substances. The SER is responsible for breaking down drugs, alcohol, and harmful toxins, thereby protecting the body from potential damage. Hence, (c) is the correct option.
