About fifty years ago, plant physiologists set out to grow roots by themselves in solutions in laboratory flasks. The scientists found that the nutrition of isolated roots was quite simple. They required sugar and the usual minerals and vitamins. However, they did not require organic nitrogen compounds. These roots got along fine on mineral inorganic nitrogen. Roots are capable of making their own proteins and other organic compounds. These activities by roots require energy, of course: The process of respiration uses sugar to make the high energy compound ATP, which drives the biochemical reactions. Respiration also requires oxygen. Highly active roots require a good deal of oxygen.
The study of isolated roots has provided an understanding of the relationship between shoots and roots in intact plants. The leaves of the shoots provide the roots with sugar and vitamins, and the roots provide the shoots with water and minerals. In addition, roots can provide the shoo
A. make proteins
B. obtain fresh air
C. produce inorganic nitrogen
D. carry out activities without energy
You wouldn’t expect an Information Age company like Intel to get on the wrong side of environmentalists, but the company’s recent 42 billion expansion at Rio Rancho, New Mexico, plunged the world’s largest semiconductor maker into an age-old Western problem: water rights.

That’s a problem in the dry West, where, as Twain remarked, whiskey is for drinking, water is for fighting about.

After weeks of public hearings, the state of New Mexico last year granted Intel 72% of the water it requested.
The strife at Rio Rancho is the most intense the industry has faced. "I think it sensitized us, "
