Which organelle modifies, sorts, packages, and secretes chemicals in and out of the cell?

Explanation:
The Golgi apparatus handles modifying, sorting, packaging, and secreting molecules. It receives proteins and lipids from the rough endoplasmic reticulum, then enzymes in the Golgi modify them—such as adding carbohydrate groups to proteins. After modification, the Golgi sorts these products and packages them into vesicles that bud off from the Golgi. These vesicles then travel to the plasma membrane to secrete contents outside the cell, or deliver enzymes to lysosomes or to other destinations inside the cell. This combination of processing, directing, and dispatching is why the Golgi apparatus is the correct organelle for this role.
