Why a cell is like a Medieval Castle
A cell membrane acts like a castle's walls. The walls control what goes inside the castle and what doesn't much like how a cell membrane controls what comes in and out of the cell
The cytoplasm is like the interior of a castle. The cytoplasm is pretty much the material that fills the inside of a cell, like the inside of a castle.
The nucleus of a cell is like a throne room of a castle. A nucleus maintains all the cell's functions. A throne room, or at least the king and his advisors inside, help decide what will happen inside the castle.
The Mitochondria of a cell is like the kitchen of a medieval castle. It is the powerhouse of the cell because it gives the cell energy (ATP) from glucose. The kitchen of a castle also provides energy to the castle, as it prepares all the food for the rest of the castle.
The endoplasmic reticulum of a cell is like the hallways of a castle. The endoplasmic reticulum transports the proteins and lipids to the other parts of the castle, much like the hallways in a castle, which help people move around the castle like the ER lets other things move around the cell.
The ribosomes of a cell are just like the craftsmen in a castle. The ribosomes create the proteins for the cell so it can function just like how craftsmen make things needed for the castle to function.
The Golgi Apparatus is just like the general workers in a castle. The golgi apparatus redistributes the proteins and the lipids from the ER just like how the general workers carry things through the hallways to the different sections of the castle.
The lysosomes of a cell are like the servants for a king. The lysosomes help dispose of waste, like old or worn out cell parts, or food particles. The servants of a king do almost the exact same thing. They clean up the place, throw away waste, and things of that nature.
The peroxisomes in a cell is like the poison tester/taster. The peroxisomes break down poisonous peroxide produced by the bodily functions of the cell. The poison tester/taster will test the food before it is delivered to the king, as if he his "getting rid" of the poison.
The chloroplasts of a cell are like a castle's kitchen gardens. The chloroplasts of a cell contains chlorophyll. It transforms light into energy and carbohydrates. This process is called photosynthesis. The kitchen gardens provide energy and cars for the meals.
The cell wall of a cell is like the moat for a castle. It surrounds the cell membrane, which is much thinner than the cell wall. It protects the cell and gives it its shape. The moat surrounds the castle walls and is much thicker than the castle walls. It also protects the castle.
The central vacuole is like the storage room or armory in a castle. The central vacuole stores water and extra materials. The storage room in a castle stores excess materials for the castle.
