Cell Parts Analogy Restaurant By: Sean King

Cell Membrane/Doors and Walls • The Cell Membrane is a thin semi-permable membrane that

surrounds the cytoplasm of a cell. The function of a cell membrane is to protect the cells interior and only allowing certain substances into it. Restaurants have doors and walls to let people into the restaurant to enjoy their meal, but the doors and walls also keep some people from getting into the restaurant, which is the similarity between a cell membrane and a restaurants doors and walls. The cytoplasm is found in eukaryotic cells.

Cytoplasm/Atmosphere of the restaurant • The Cytoplasm is clear with no color, and has a gel-like

appearance. The Cytoplasm consists of all the contents outside of the nucleus. In other terms, the cytoplasm is the atmosphere of the nucleus which is containing all of the organelles in a cell. The atmosphere of a restaurant compares to this due to the customers of a restaurant just being inside of the restaurant. The cytoplasm can be found in eukaryotic cells.

Nucleus/Manager • The Nucleus is a membrane that holds the cells heredity,

information, and controls. It controls on how the cell grows and the reproduction of a cell. What the nucleus does is tell what the cell does and how it will function. This relates to a manager, because of what the manager does which is tell the waiters what to do and basically controlling them. The nucleus can be found in eukaryotic cells.

Endoplasmic Reticulum/Waiters • The Endoplasmic reticulum usually surrounds the nucleus. It

is made of a series of membranes in eukaryotic cells. Endoplasmic reticulum's are tubular networks that stores, separates, and serve as a cell’s transport system. Waiters are similar to these organelles because of how waiters transport food to customers in a restaurant and separate foods so that each food that someone orders goes to them.

Ribosomes/Ovens and Other kitchen appliances • Ribosomes are very small and create proteins for the cell,

they also consist of RNA. Their function is to make sure that proteins get assembled for the cell. Ribosomes compare to Ovens and other kitchen appliances since ovens create food(a chef could also count) and then that food gets served to the customers of the restaurant. Eukaryotic cells contain ribosomes in them.

Nucleolus/assistant manager. • The Nucleolus contains all of the DNA that a cell

may carry. It is used as the instructions to create building blocks of the cell. It can also be used for cellular reproduction. The reason why a Nucleolus is similar to a assistant manager is that the nucleolus also controls a certain amount of organelles in the cell just not as much as the cell making the Nucleolus the assistant manager for the nucleus.

Mitochondria/energy source• The Mitochondria serve as a engine house for the cell. It

converts energy to forms in which that are usable by the cell. You can find the Mitochondria in the Cytoplasm, mitochondria’s are sites for cellular respiration. An energy source like a generator would be comparable to a Mitochondria since they both generate energy for places. Mitochondria’s are found in eukaryotic cells.

Golgi Body/Packing Department • The Golgi Body sends and receives material in a cell. It can

be found in eukaryotic cells. A Golgi body can be compared to a packing department because of how a packing department receives items from manufactories and then send items to restaurant, stores, etc.

Vacuole/freezer and storage room• A Vacuole serves as storage of materials for the

cell. Vacuoles have many functions one of them is maintaining an acidic internal pH, containing small molecules, exporting unwanted substances from the cell, and containing water in plant cells. A freezer or a storage room would be very comparable since they both store items that may be used for later. Vacuoles are found in plant cells(eukaryotic cells).
