Plant root hairs help to absorb carbon dioxide from the soil.
Root hair cells
Plants absorb water from the soil by osmosis. They take up mineral ions by active transport against a concentration gradient. Root hair cells are well-suited for absorbing water and mineral ions because of their large surface area and high absorptive capacity.
It also contains many mitochondria, which release energy from glucose during respiration to provide the energy needed for active transport.

Carbohydrates are chains of monosaccharides. Hydrolysis involves the addition of a water molecule that cleaves the covalent bond between the molecules of sugar.
The reverse reaction is a condensation reaction, the joining of sugar monomers to create a carbohydrate releases a molecule of water.
