WebNARRATOR: In most land plants, oxygen and carbon dioxide enter through the leaves, while water and mineral salts enter through the root system. Substances can move into the root in several ways, with the principal method being osmosis. During osmosis free-water molecules pass from the soil into the epidermal cells, using the root-hair membrane.
