Cell City: An Educational Comparison of Cell Organelles to a City Infrastructure

Explore the fascinating world of cell organelles by comparing them to familiar structures in a city, highlighting their functions and importance in both settings. From the nucleus as the control center to the mitochondrion as the power plant, discover the similarities between cellular components and urban infrastructure. Learn how the cell membrane, cell wall, endoplasmic reticulum, Golgi apparatus, vacuole, and ribosome mirror functionalities seen in a police station, water levy, trains, post office, grocery store, and restaurant respectively. Gain insight into the unique features of plant cells and animal cells, emphasizing differences such as the presence of a cell wall, chloroplasts, and central vacuoles in plant cells compared to the absence in animal cells. Enhance your understanding of biological concepts using relatable urban comparisons.

  1. Cell Organelles Created by: Ashley Brook Proffitt

  2. Nucleus Court House • The nucleus is known as the control center of the cell. • The Court House is the control center of a city.

  3. Cell membrane Police Station • The cell membrane is responsible for controlling what goes in and out of the cell. • Police officers enforce laws and controls what goes in and out of a city.

  4. Cell wall Water Levy • The cell wall is responsible for the structure of the cell. It also supports and protects it. • A water levy protects a city from being flooded.

  5. Endoplasmic reticulum Trains • This organelle is responsible for providing passages for proteins to move through easily. • Trains provide passages for the people in a city to get from place to place.

  6. Golgi apparatus Post Office • This organelle is responsible for packaging and sending out proteins to other parts of the cell. • In a city the post office is responsible for sending out packages to the citizens.

  7. Mitochondrion Power Plant • Also known as the power house of the cell, it is responsible for producing energy. • A power plant in a city is responsible for making sure that the area has electricity to keep things running smoothly.

  8. Vacuole Grocery Store • Storage is the main duty of this organelle. It stores waste, food, water, etc. • A grocery store stores all types of things in a city. You can go there at any time and purchase food or water.

  9. Ribosome Restaurant • The ribosome of a cell is responsible for producing proteins in a cell. • The food that is prepared in a restaurant contains proteins for people to eat on a daily basis.

  10. Plant Cells Animal Cells • Have a cell wall (on outside) • Have photosynthesis and cell respiration • Green due to chlorophyll • Have chloroplasts • Square due to cell wall • 1 large central vacuole • Have cytoskeleton (on inside) • Does cell respiration only • White/pink/red due to blood • No chloroplasts • Can be any shape • Many small vacuoles
