Why does a cell tower need to be massive to transmit data to a smartphone but the phone’s extremely small antenna can transmit data back over the same distance?

It’s also big because it can receive weak signals.
Imagine that your phone is someone signaling by using a cheap flashlight in a field. Hard to see from far away.
Now the cell tower is a spotlight and a telescope. They can see the tiny flashlight with the scope, and reply with a massive light.
On top of that, they also need to be able to talk to tons of phones at a time as well as communicate over the landlines. So they need a lot more equipment and power than your phone.
