2-the electric charges on the individual water molecules tend to attract other water molecules
3-the chemicals from the plant change water into a new substance
4-the leaf absorbs all of the electrical charges from the water molecules
It's called surface tension. The water molecules tend to defy gravity as they hang together, even in a downward arc. This phenomenon makes it harder to get total penetration, for instance, into a garment that you're trying to wash and get the grime out.
