Transcript of Cell Comparison to a Car

Chloroplast is an organelle found in a cell that takes in carbon dioxide, water and captures the energy found in sunlight (ATP) and converts that into oxygen and sugar. Chloroplast helps plant cells preform photosynthesis.
The Mitochondria
The mitochondria is an organelle that converts energy into a form that is usable to that cell. It is fundamentally the "power house" of that cell because they generate most of the energy to power a cell.
Plant Cell Comparison to a Car

Golgi apparatus
The Golgi apparatus packages and process macromolecules like proteins and lipids that have been synthesized in the endoplasmic reticulum . It releases thse things into the cell for further use
Cell Wall
The cell wall is the outermost part of the plant cell. The cell wall is a rigid structure that surrounds the plasma membrane. It is composed mostly of cellulose that is a tough, rigid cellular structure. The main purpose of the cell wall is to protect the cell and also to regulate the life cycle of the cell.
The Nucleus
The nucleus can be compared to the driver of a car. The nucleus of a plant cell controls the cells activities. Just like a driver controls what the vehicles does and where it goes.
The nucleus of a cell also controls the inheritance of the cell. It is the main power center where it holds complex DNA called chromatin which makes up the cell's chromosomes. Just like the nucleus controls the genetics or "inheritance" of what future cells will be like, the driver controls who will own the car once he decides to give it up.
The mistochondria can be compared to an engine of a car because without the engine of a car, the car would not be able to function. The engine is where gasoline is changed into energy that can power the car.
Chloroplast can be compared to the gas tank of a car. The cas tank of a vehicle "captures" gasoline. Just as in chloroplast organelles, a gas tank is where energy enters originally.
The cell wall can be compared to the metal around the frame of the car. The metal of the car protects the contents inside the car from the outside. Like the cell wall, the metal of the car is rigid and not likely to loose its structure.
Ribosomes are found in the cytoplasm of the cell and are used for protein synthesis. Ribosomes assemble amino acids into polypeptides.
Ribosomes can be compared to the transmission of a car. The transmission of a car is where the steering wheel, gas pedals, and clutch are found. This is where the controlled part of functioning the car is used. Just like Ribosomes, without the appliment of the transmission, the car could function, but it would not go anywhere.
The Endoplasmic Reticulum
The endoplasmic reticulum serves as the transportation for the plant cell. It also manufactures and processes chemicals for the cell. It is used to connect the nucleus to the cytoplasm and functions in a way as a median between the two (it contains ribosomes). It is involved with the synthesis of proteins and lipids.
The endoplasmic reticulum can be compared to all the pipes and electrical circuits found throughout the car. Like the endoplasmic reticulum, the pipes and wires carry many different things to every other place within the car. It can range from electricity to even fuel. The endoplasmic reticulum serves the same purpose of transportation
The vacuole is a part of a plant cell that functions as the storage unit for the cell. The vacuole contains and exports toxins/wastes, stores small molecules (salts, minerals, pigments), and removes yucky things floating around in the cytoplasm. A plant cell has a single vacuole that takes up about 80 percent of the cell's space. Because of this, the pressure maintains the cell's shape which is the reason the vacuole helps uphold a celld structure.
The vacuole of a plant cell can be compared to the trunk of a car. Like the vacuole of a cell, the trunk is used for storage of many different things. Those things can range from foods to yesterday's trash that about to go to the dump. The trunk is usually where unwanted things end up. There is also only one trunk per car, just like there is only on vacuole per plant cell. The trunk does not uphold the cars shape but it is involved in a large part of the structure of the car.
Cell/Plasma Membrane

The Golgi apparatus can be compared to the arms of the driver giving the Starbucks coffee to the passengers in the backseats. Like the Golgi apparatus, the arms are delivering items to other areas of the "cell" (car).
Cytoplasm fills the spaces between the organelles. It is a jelly-like liquid that is eighty percent water. Cytoplasm contains nutrients for the plant cell and also helps dissolve waste.
The cytoplasm can be compared to the air of the car. like cytoplasm, the air in the car takes up a lot of space and is in between all of the objects within it. Air also provides nourishment to the people within it because without air (oxygen), the people inside would die
The cell membrane (also called the plasma membrane) is a thin layer after the cell wall that regulates what enters the cell and also what leaves the cell. It is semi-permeable. Cell membranes use a method called diffusion. The cell membrane also holds in all the contents within the cell
the cell membrane can be compared to the doors of a car. the doors of a car act as a barrier between the outside and also keeps thing on the inside. Like the cell membrane, the car doors "decide" what to let into the car (aka the "cell")
The Nucleolus

The nucleolus is found within the nucleus and is full of nucleic acids and proteins. It is the spot where RNA is synthesized
The nucleolus could be compared to the data chip of a car. It has the main information that controls the car.

Nuclear envelope
Plasmodesmata are organelles that connect directly to the cytoplasm of neighboring plant cells.
Plasmodemata can be compared to the booster seat of a child's. The booster seat connects directly to the seat of the car and connect the child to the car (the cell)
The Cytoskeleton consists of
Microtubules. Microtubules are fibrous hollow rods that help supports the shape of the cell. They are also involved in cell division.
intermediate filaments. Intermediate filaments are fibrous proteins that supports cell structure. Intermediate filaments use tension between one and other to maintain shape in the cytoskeleton They can also be found in the inner nuclear membrane to hold the shape of the nucleus. I
Microfilaments. Microfilaments are proteins that support cell structure as well.

The cytoskeleton can be compared to the frame of the car. The frame is rigid and supports the structure off the sheet metal and everything else in the cell
Peroxisomes consist of around 50 different enzymes combined together to rid the plant cell of toxins throughout the cell (mainly hydrogen peroxide.). They use oxidation reactions to do this.
Peroxisomes can be compared to the exhaust of the car. The exhaust of the car rids the car (the "cell") of wastes and toxins that decrease the function of the car (the "cell") because they are not useful and can cause harm to it. Like the exhaust, peroxisomes get rid of toxins.
The nuclear envelope is a double layered membrane that envelopes the nucleus separating the nucleus from the cytoplasm of the cell. It has pores to regulate what goes into the cell and what goes out. (RNA, protein, ATP, water ect.)
The nuclear envelope can be compared to the seat belt of the car. The seat belt of the car isn't the greatest comparison but it's the best one for this scenario. The seat belt creates a barrier from the driver (the nucleus) and the air (the chloroplast). It also has openings to allow things through it.
Chromosomes or chromatin are what allows the cell to reproduce and pass on it's genetic information. Chromosomes are mad up of DNA and are found in the nucleus between the nuclear envelope and the nucleolus
Chromosomes can be compared to (along with the nucleolus) as the computer chip in the car. The computer chip holds all information that makes the car function. Like chromosomes, the only reason the car (the cell) works is because of the information stored in the chip (the DNA)
