This cellular structure is responsible for making proteins that will be used either inside or outside of the cell. There are two types; free and bound. They receive their instructions from the DNA of the cell.

• Smooth ER

• Ribosomes

• Rough ER

• Golgi

This cellular structure acts as the gatekeeper of the cell. It protects the cell and determines what comes in and what goes out of the cell.

• Cell membrane

• Cell wall

• Chloroplast

• MItochondria

This organelle is found in plant cells, but not in animal cells. It uses sunlight, water, and carbon dioxide to make sugars to be used for food in a process called photosynthesis.

• Cell wall

• Central Vacuole

• Mitochondria

• Chloroplast

This organelle makes lipids and helps to detoxify the cell of poisons and drugs.

• Smooth ER

• Rough ER

• Golgi

• Mictochondria
