In biology class, our teacher explains about cells.

I fall asleep and start fantasizing.

I imagine what the life of cells could look like.

I see a thought bubble appear above my head.

My teacher and I are in the cell factory.

The teacher shows me around the factory.

We visit the cell nucleus, the control center.

Workers (ribosomes) make proteins.

The endoplasmic reticulum transports and modifies proteins.

The Golgi apparatus prepares and sends proteins.

The mitochondria produce energy in the powerhouses.
