The copper reacts with the oxygen in water to form copper oxide and hydrogen ions. This is copper oxide is a green compound.
Actually if you take a penny and "water" it or place it in water within a couple days it will become green.
Assuming you are talking about the leaves, it is because they have chlorophyll which is a green pigment.
yes without plant carbon dioxide can still turn the water green
I would recommend against it as it is illegal, but you would need zinc and heat to turn a copper penny to brass.
A penny is a solid, flat object and does not hold much water at all.

The pennies turn green because they are open to the air, because they contain copper, and because copper turns green when oxidized.
the Statue of Liberty is green because it has been there for a long time. Since metal rusts, the Statue of Liberty also rusted. In fact, it rusted enough for it to turn green. If a penny rusts enough, it will also turn green.
it would turn a dark color green

Pennies are made, or at least coated, with Copper and that copper can oxidize and turn green. Newer pennies have an alloy metal that is supposed to reduce this chemical action.
