I think they connect because the human is controlling the car and that’s what the nucleus does in the cell.

I think chloroplasts and gas connect because chloroplasts is sorta the food and the gas is the food to the car because it helps the car go.

I think the engine and the mitochondria connect because the mitochondria is the energy and that’s what the energy does.

The cell wall gives the shape and so the doors on a car give the shape because the frame has to fit what the doors look like.

The cytoplasm and the frame are sorta the same because because the cytoplasm holds the structure up.

The vacuole stores material and stuff and so the gas thank holds the gas in it.
