Functions of Organelles in a Cell

Question	Answer
Mitochondria	Produces energy for the cell. Made of a double folded membrane.
Nucleus	Controls cellular activity. Think of it as a control centre. A large organelle that contains genes.
Endoplasmic Reticulum	Two types: 1)Smooth- doesn't contain ribosomes. Transports substances. Produces lipids. 2)Rough- contain ribosomes. Found near the Nucleus. Transports protein to the Golgi body
Ribosomes	Produce protein. Found on the rough endoplasmic reticulum.
Cell Membrane	Keeps all the organelles together. Controls what enters and exits the cell. Found in BOTH plant and animal cells.
Cell Wall	ONLY found in PLANTS. Provides protection and support for the organelles. Shapes cells.
Golgi Apparatus (Bodies)	Changes, stores and distributes substances created by the endoplasmic reticulum.
Vacuole	Stores water and other substances. In plant cells it tends to be one large vacuole, and several small ones in animal cells. They also provide some support/structure to the cell.
Chloroplast	ONLY found in PLANT cells. The area in which most cellular activity occurs due to photosynthesis. Tends to be green in colour when viewed under an electron microscope without any dye.
Lysosomes	Help break down and destroy damaged cells.
