What allows water to move from a plant’s roots to its leaves?

• adhesion only

• cohesion only

• adhesion and cohesion

Water can dissolve many substances because of its

• density.

• polarity.

• cohesion.

Describe the polarity of a water molecule.

• Water molecules are non-polar.

• Water molecules have a positive and a negative end.

• Water molecules are positively charged.

• Water molecules are negatively charged.

Explain how water’s polarity affects its ability to dissolve other substances.

• It makes water unable to dissolve substances.

• It allows water to dissolve only non-polar substances.

• It allows water to dissolve many different substances.

• It makes water dissolve substances very slowly.

Compare and contrast cohesion and adhesion as they pertain to water.

• Cohesion is water sticking to other substances; adhesion is water sticking to itself.

• Cohesion is water sticking to itself; adhesion is water sticking to other substances.

• Cohesion and adhesion are the same.

• Cohesion is water repelling other substances; adhesion is water repelling itself.
