Nucleus

contains cell DNA

Ribosomes

make protein for the cell

Cytoplasm

Endoplasmic Reticulum

moves materials around in the cell

Golgi Apparatus

used for packing and secreting

Vacuole

storage areas for the cell

Lysosomes

chemicals used to digest waste

Chloroplast

break down food and release energy to the cell

Cytoskeleton

provides support for organelle and is important in cell locomotion

Cilia and Flagella
