If water molecules (H2O) suddenly stopped forming hydrogen bonds with one another, how would water transport in vascular plants change (if at all)?
A. It would remain the same, as H2O molecules also form oxygen bonds. B. It would remain the same, as water transport only depends on osmosis. C. It would stop, as water transport relies on H2O molecules being connected by hydrogen bonds. D. It would increase, as hydrogen bonds inhibit water transport.
