Plant Cell as a Car
Transcript of Plant Cell as a Car
The nucleus of a cell can be compared to the driver of a car. Without a driver, the car cannot function. The driver of a car controls the car's activity and allows the car to move (drive), but only under the driver's control and demand. A car depends on its driver to function, just as a cell depends on its nucleus. The Cell Wall The cell wall of a plant cell is very important. The cell wall of a cell is what makes and maintains the cell's shape. It also provides structural strength and support to the cell. The cell wall of plant cell protects the cell from mechanical injury or getting damaged. Without this protective casing, the cell could easily become damaged.
The cell wall of a plant cell is very similar to the outer shell of a car. A car's outer shell creates the car's shape and provides a strong support that holds the car together. It also protects the people inside of the car in the event of an accident. Mitochondrion The mitochondrion of a plant cell serve as the cell's fuel source; they generate most of the cell's supply of energy. The mitochondrion convert energy into forms that are usable by the cell, and are often referred to as the "power houses" of the cell. They are the sites of cellular respiration within the cell, which generates fuel for the cell's activity.
The mitochondrion of a plant cell can be compared to the engine of a car. The engine of a car converts gasoline into energy, which fuels the car and helps it function, just as the mitochondrion fuel the cell with energy, which generates power for it's activity. The Endoplasmic Reticulum The endoplasmic reticulum of a plant cell has two parts to it; the smooth ER and the rough ER. The smooth ER's job is to make lipids and hormones, while the rough ER has ribosomes attached to it, which create proteins. Both transport substances throughout the cell and are referred to as "cellular highways".
The endoplasmic reticulum of a plant cell is similar to the wires and pipes of a car. These wires and pipes transfer and carry materials around the car, just as the endoplasmic reticulum carries and transfers substances around a plant cell. Vacuole The vacuole of a plant cell stores food, water, and waste. When there is enough water in a plant cell, the solutes in the vacuole attract water in a process called osmosis. The cell then becomes inflated, which gives support to the soft parts of the plant, such as the leaves. When you do not water your plants, they wilt because there is not enough water in the vacuoles to provide support.
The vacuoles of a cell are like the trunk and other compartments of a car. These compartments of a car serve as a storage space for materials, just as the vacuoles serve as a storage space for water, food, and waste in a cell. Lysosomes The lysosomes of a plant cell serve as the "digesters" of the cell; they break down cellular waste. Lysosomes break down the worn out parts of a cell and help to get rid of unwanted waste products that are created in parts of the cell.
The lysosomes of a plant cell can be compared to the exhaust pipes of a car, which allow waste products to be taken out of the car. Lysosomes behave the same way within a cell by helping to get waste out of the cell. Golgi Body The golgi bodies, also known as the golgi apparatus, package proteins and carbohydrates within a cell into vesicles for "export" from the cell. These proteins and carbohydrates are distributed all around the cell. Without golgi bodies in our cells, our cells wouldn't be able to function properly.
Golgi bodies can be compared to the carburetor on an engine of a car. The carburetor packages fuel and air, and then circulates the mixture throughout the engine, which allows it to function; just as the golgi bodies package proteins and carbs and send them throughout the cell. The ribosomes of a plant cell could be compared to the controls between the driver and the car, such as the steering wheel and pedals. The nucleus can be compared to the driver of the car. The ribosomes create proteins for the nucleus to use, just as the controls of a car help create the movement of the car for the driver. By Sarah Edgerton
