The mitochondria provide energy that is needed for the uptake of water.
Explanation:
The main purpose of the roots is to absorb water and mineral ions from the soil through osmosis and active transport. This process relies on the specialised root hair cells, which are located just behind the tip of the roots.
The root hairs contain many adaptations that maximise the uptake of water. One of the most important is the high number of mitochondria. These organelles release energy from glucose during respiration. This energy, in the form of ATP, enables active transport to occur and greatly increases the uptake of water in the roots.
