Front

What process describes water evaporating from plant leaves and drawing water from roots?

Back

Transpiration, which involves cohesion and adhesion.

Front

Define cohesion in the context of water molecules.

Back

Cohesion is the attraction between water molecules due to hydrogen bonding.

Define adhesion in the context of water and other substances.

Back

Adhesion is the attraction between water molecules and other substances.

Front

What is a macromolecule?

Back

A large molecule composed of smaller subunits, such as proteins, lipids, carbohydrates, and nucleic acids.

Front

What type of bond allows carbon to form extensive carbon skeletons?

Back

Covalent bonds.

Front

What is the significance of hydrogen bonding in water?

Back

Hydrogen bonding gives water its unique properties, such as high surface tension and specific heat.
