Transcript of Cell Analogy
The nucleus is the manager of the cell that directs all of the cell's activities. My metaphor for this term is the main office in a factory.
The endoplasmic reticulum is a network of folded membranes and tubes connected with the nucleus.
Cell membranes control what go in and out of the cell. In a factory, that is like the front doors.
Lysosomes are in special vesicles and their job is to degrade various materials with the help of digestive enzymes. In a factory, this is like a recycle room where they find a way to break down waste and bad products.
Golgi apparatus is an organelle in which its membrane fuses with the membrane of the vesicle membrane. The molecules are then modified by enzymes and made fully functional. Then, it sorts and repackages the molecules into vesicles and distributes them to other parts of the cell. In a factory, this would be the warehouse in which products are stored before exporting.
Mitochondria is the source of energy for cells to do work. Inside it, chemical reactions convert the energy into forms that the cell can use. In a factory, this would be the powerhouse that is used to run the factory's power.
Centrioles are cylindrical structures located just outside the nucleus. Its role in cell division is to help move genetic material correctly into each new cell. In a factory, it would be the secretary.
Vacuoles are balloon-like vesicles that provide storage space for water, food and minerals in the cell. The metaphor for this would be the storage closet where stuff are stored.
Chloroplasts are the organelles of photosynthesis that collect sunlight in plants. The metaphor for this would be solar panels used in factories.
My Metaphor is a factory!
The difference between an animal and plant cell is that animal cells do not have chloroplasts and cell walls while plant cells do.
The cytoplasm is a jelly like fluid that suspends all the contents of the cell held together by the cell membrane. It helps move organelles throughout the cell. In a factory, that would be the whole factory minus the nucleus.
Vesicles store or transport materials in and out of the cell. In a factory, this is like the break room. This is where workers take a break, eat food and deposit waste.
The nucleolus is used for creating and sending ribosomes. In a factory, it is the boss of the main office.
The rough endoplasmic reticulum is studded with ribosomes that build proteins. These are then packaged in vesicles for transport. The metaphor for this would be an assembly line where workers assemble the products.
Rough Endoplasmic Reticulum
The smooth endoplasmic reticulum has no ribosomes. it synthesizes lipids and packages large molecules (proteins and lipids) in vesicles. they are then transported to other parts of the cell. in a factory, this would be the hallways where information from the main office is sent to workers of all departments.
Smooth Endoplasmic Reticulum
Ribosomes are organelles in a cell that build proteins. The metaphor for this would be the workers who take the orders form the boss and execute them.
Cell walls are rigid and supportive and protect the outside of the cell. In a factory, this would be the walls of the factory that give it support.
Nuclear Pores are large protein complexes that cross the nuclear envelope and flow between the nucleus and the cell. In a factory, this would be the doors of each department so they can communicate easily.
Nuclear envelope is information encoded in the DNA copied in the form of messenger molecules. It is also called the nuclear membrane. My metaphor for this is a gaurd who protects the main office(nucleus) and chooses who goes in and out.

So that is how an animal and plant cell parts relate to a factory. just like we have systems that run our body, cells do to. From giant mechanical systems in factories to small biological systems in our cells and body, everything runs on systems, It all depends on how you see it!
