: If chemically nothing is ever created or destroyed but simply transformed, where does the matter come from when a sperm cell grows to a full body?

Question

I know obviously how the cell divides and becomes more and more complex over time. I get that the biological code is in the original cell, but where does the matter come from? In my mind, I imagine the first cell as an architect with all the blueprints, but without any material. It doesn’t pop out of nowhere, right?

That’s why your mommy eats for two.

All the nutrients and food she eats gets converted to raw building blocks, that get fed to the baby.

This is also why mommies need to be extremely careful not to eat or drink certain things while pregnant. It all passes to the child.
