Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.
Answer:
Respiration links up the simple sugar, <u><em>glucose</em></u><em>,</em> with the gas <u><em>oxygen .</em></u>
Explanation:
In the process of respiration, oxygen is used to breakdown glucose. Water and carbon dioxide are produced due as a result of this reaction. A huge amount of energy, in the form of ATP is also released during this process. ATP is used by almost every cell of the body to carry out normal cellular functions. Energy is mainly stored in the linkage between the second and third phosphate of an ATP molecule.
