NUCLEUS The Nucleus of a plant cell and the driver of a car performs similar functions in their respective systems. The nucleus controls all cell activities such as reproduction and growth. It carries all the instructions. Likewise, the driver is the one who controls the car in areas such as direction and speed. However, The Cell nucleus contains DNA which determines the characteristics of the cell while the driver in this case has no say over how the car will appear to be. It is the liberty of the designer and company to construct and design the car.

Plasma Membrane The Cell Membrane is partially permeable and controls the movement of substances entering and leaving the cell. Likewise, the Car door acts as the invisible membrane between the surrounding and the inside of the car. It only allows certain people (the keyholder) to get into the car as there is a lock system to stop others from entering as well. However, the car door requires an external factor to prevent others from entering: the driver to press the lock. In the plant cell, the cell membrane can perform its function by itself.

CELL WALL A plant cell wall has many important jobs. The main two jobs it has are to provide protection and support for the plant. In fact, it is the cell wall that gives the plant its actual shape. It acts as a gatekeeper, determining what can come in and out of the cell, in order to keep the cell protected.Similary, the outer frame of the car creates the car’s shape and provides a strong support that holds the car together. It also protects, the peope inside of the car. However, the cell wall is fully permeable and allows all substances to enter the plant. This does not apply to the outer frame of the car. Not everything can pass through it, in fact, nothing can unless through the door.

Ribosomes Ribosomes perform similar functions as a steering wheel in their respective systems. Ribosomes are sites of protein synthesis. Proteins are needed to carry out cell activites and as energy outside the cell. Likewise, the steering wheel is the control between the driver and the car

Lysosomes The main function of lysosomes is to break up waste material.They also digest or engulf excess or worn-out organelles food particles and bacteria. The exhaust system guides the exhaust gases away from a controlled combustion inside an engine or stove. Likewise,the exhaust system removes the unwanted gases from the combustion reaction, like a lysosome removing unwanted waste from the cell.

Golgi Complex The golgi complex is often referred to the post office of a cell. It sorts out and arranges the protein into packages to be sent to the appropriate destination. The car has a check valve to move substances such as fuel or gas into the right direction or location. It filters and send the proper substance into the appropriate direction.

Chloroplasts chloroplasts and Solar Power Panels perform similar functions in their respective systems. Chloroplasts contain green pigment for light absorption. Through photosynthesis they convert light energy into Adenosine Triphosphate and sugars. Likewise, Solar cars can accomplish this through photovoltaic cells (PVC). PVCs are the components in solar paneling that convert the sun's energy to electricity. However, enzymes are also necessary for the production of Glucose during photosynthesis. This means that chloroplasts alone are not adequate for plants. This is not the case for solar panels, they are enough to do conversion into electricity.

Rough ER The rough ER is like the gas tank because they both store thing. The rough endoplasmic reticulum stores proteins and pacts them. They both are staggered in order to become stronger.

Smooth ER The Smooth Endoplasmic Reticulum (ER) performs a similar function as a catalytic converter in their respective systems. The Smooth ER is a network of tubules and flattened spaces lined by membrane. It synthesizes fats and steroids (i.e Cholesterol, sex hormones) They convert harmful substances into harmless materials through Detoxification. Likewise, A catalytic converter provides an environment for a chemical reaction wherein toxic combustion by-products are converted to less-toxic substances. However, the smooth ER is a network of tubules. Though the Catalytic Converter is part of a wiring system, it performs the function of conversion alone.

Vacuoles 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 part parts of the plant, such as the leaves. When you do not water your plant, they wilt because there is not enough water in the water in the vacuoles to provide support. The vacuoles of the cell are like the trunk and other compartment of a car. These compartments of car server as a storage space for materials, just as the vacuoles serve as a storage space for water, food, and waste in a cell.

Cytoplasm The cytoplasm of a cell contains both the jelly-like substance inside a cell, called cytosol. the cytoplasm gives the cell volume. A cell having liquid volume is important because it also allows for materials inside the cell to transport between organelles more easily.

Centrioles The centrioles function as the microtubule organizing center, it is an important event in major cellular process, that is cell division and flagella formation The spindle fibers are responsible for the segregation of chromosomes into the daughter cells.
