Why the bonds matter: covalent bonds because it is very difficult to break these bonds. If you ever put that stuff on your windshield to make water bead off: it helps plants greatly.

Plants need water for food , and at times structural support. Humans are about 70% water: brains 95%water, dehydration at around 2% loss.
