written reposes Drew visits a coal-fired power plant with his class. He learns how the power plant works: 1. Coal is delivered to the power plant. 2. The coal is ground to a powder and mixed with air. 3. The air and coal mixture is burned at very high temperatures in the firebox of a boiler to produce heat energy. 4. Water piped into the boiler is heated and becomes steam under high pressure. 5. The high-pressured steam spins a turbine (blades that spin under pressure, similar to a propeller). 6. The turbine is connected to a generator, where magnets turn inside of wire coils to produce electricity. Drew decides that the function of a coal-fired power plant is similar to the function of a part of a cell. a. Identify the cell part that functions in a similar way to a coal-fired power plant. b. Describe how the coal-fired power plant and the cell part identified in part (a) are similar in function.
