What is the function of the Golgi apparatus?

Processing Energy

Most eukaryotic cells contain mitochondria, where
energy-releasing reactions occur.

Chloroplasts are membrane-bound organelles
that use light energy and make food—a sugar called
glucose—from water and carbon dioxide through the
process of photosynthesis.

Processing, Storing, and
Transporting Molecules

The Golgi apparatus prepares proteins for their
specific functions and packages the proteins into
vesicles.

Vesicles are organelles that transport substances
from one area of a cell to another area of a cell.

Vacuoles—organelles found in some cells—store
food, water, and waste material.
