Golgi Complex (Golgi Body)

Packages and ships proteins and materials.

Lysosomes

Break down waste and old cell parts

Vacuole

Stores water, food, and waste

Centrioles

Help the cell divide during cell reproduction

Microtubules

Give support and shape to the cell. Help move materials.

Microvilli
