Capillary attraction - CORRECT ANSWERS ✔✔The movement of
|\ |\ |\ |\ |\ |\ |\ |\


water into and through small openings. This helps plants to get
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


water from their roots up to their leaves
|\ |\ |\ |\ |\ |\ |\




Surface tension - CORRECT ANSWERS ✔✔The force between
|\ |\ |\ |\ |\ |\ |\ |\


water molecules at the surface of the drop. Insects use this force
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


to "stand on" the water.
|\ |\ |\ |\

negative charge. These charges cause water molecules to attract
