Cell Organelles and Their Functions

Vacuole

• Storage bin for water, food, nutrients, and waste

• Site of protein synthesis

• Powerhouse of the cell

• Control center of the cell

Rough Endoplasmic Reticulum

• Manufactures and packages proteins

• Synthesizes lipids

• Detoxifies harmful substances

• Stores genetic information

Nucleus

• Brain of the cell

• Powerhouse of the cell

• Control center of the cell

• Site of protein synthesis

Golgi Body

• Gathers and sorts molecules and then packages them

• Produces energy for the cell

• Synthesizes proteins

• Breaks down waste materials

Centrioles

• Help cell divide

• Store genetic information

• Produce energy for the cell

• Transport nutrients within the cell

Cell Membrane

• Rigid structure that protects the cell

• Flexible material that holds the parts of cell together.

• Inflexible barrier that prevents substance movement

• Solid layer that provides energy to the cell

Ribosome

• Connects amino acids to build proteins

• Transports oxygen in the blood

• Stores genetic information

• Breaks down waste products in cells

Lysosome

• Removes cell waste

• Produces energy for the cell

• Synthesizes proteins

• Transports materials within the cell

Nucleolus

• Sphere shape in the nucleus makes ribosomes

• Flat structure that synthesizes DNA

• Round organelle that produces ATP

• Membrane-bound structure that stores proteins

Cytoplasm

• Fluid that fills cell and suspends organelles

• The outer membrane of the cell

• The control center of the cell

• A type of cellular respiration
