TERM 1
Polar Molecule
DEFINITION 1
that the two ends of the molecule have opposite charges
TERM 2
Cohesion
DEFINITION 2
the bonding together of like molecules, likely by hydrogen
bond
TERM 3
Adhesion
DEFINITION 3
the clinging of one substance to another. Adhesion of water
to cell walls by hydrogen bonding helps counter the
downward pull of gravity
