Welcome to Cell City, where the tiny architects work tirelessly, building and maintaining the city's structures. Each architect knows just how to keep the city running smoothly.

Every building in Cell City is surrounded by a sturdy wall, much like the city itself. This wall, the cell membrane, protects the buildings and controls who enters and leaves.

One of these architects, Molly Molecule, guards the gate. She's an expert in signaling, deciding which nutrients can enter and which waste goes out.

Molly shows us the cell membrane's structure, a formidable double layer, filled with gatekeepers that keep the city in balance.

Beyond the wall lies the city's compartments, each with a specific purpose. The architects are proud of their efficient city planning.

The biggest compartment is the City Center, where the main architect, Danny DNA, stores the city's blueprints. Plans for every building are carefully kept here.

With a plan in hand, the architects work in the Factory Field, where they craft all the city needs. Molly mentions that this is where proteins are made.

Danny explains that just like City Center's blueprints, a cell's DNA holds instructions. Every architect knows how to read these instructions to build properly.

Molly introduces us to Terry Transporter, who operates the city's transit system. Terry ensures resources reach the correct compartment.

Terry's work highlights the importance of structure-function relationships. A transporter's design is special so it can move things efficiently within the city.

As we tour the city, the architects proudly share the complexity of their work. They know their structures and functions are interconnected for Cell City's life.

In the end, the architects remind us that every part of Cell City is essential. Together, they create a bustling, vibrant community, full of life.
