The Cell is like a truck because a truck has many different parts and works the same way as a cell does. A Nucleus is like a vehicle computer because the computer controls everything the vehicle does. The Cell Membrane is like a fuel filter because the filter catches trash in it and lets the clean go through. It only lets clean fuel go to the engine. The Cell Wall is like a vehicle frame because the frame supports the vehicle and gives it structure. The Endoplasmic Reticulum is like a fuel line because it carries gas to the intake. The Golgi Apparatus is like a fuel pump because the fuel pump pumps gas from the tank through the gas line. The Mitochondrion is like an engine because the engine is what produces all the power. The Vacuole is like a gas tank because the tank stores the gas until it the vehicle needs it. The Ribosome is like a piston/cylinder head because this is where the fuel combusts and produces power. The plant cell has a cell wall for structure and support . This is located on the outside of the cell. The animal cell has a cytoskeleton for structure and support. This is located on the inside of the cell, somewhat like our human skeleton. A plant cell is always square and an animal cell can be any shape. A plant cell goes through a process called photosynthesis and also cell respiration. An animal cell only goes through cell respiration. Plant cells have only one large, central vacuole. Animal cells have many small vacuoles.
