$(a)$ What would happen to the life of a cell if there was no Golgi apparatus?
$(b)$ Which cell organelle detoxifies poisons and drugs in the liver of vertebrates?

(N/A) If there were no Golgi apparatus,the materials synthesized near the $ER$ would not be packaged,modified,stored,or transported to various targets inside and outside the cell. Furthermore,the formation of lysosomes would not take place,as they are produced by the Golgi apparatus.
$(b)$ The smooth endoplasmic reticulum $(SER)$ is the cell organelle responsible for detoxifying many poisons and drugs in the liver cells of vertebrates.
