问题 材料分析题

2008年8月4日,一位上海中医药大学生在他到曙光医院挂职的感悟中这样写道:这次的挂职锻炼是我走向社会的第一步。我从中学习颇多,感悟颇多。长大并没有想象中那么开心,它意味着付出。好不容易放了暑假,本以为可以顺理成章地睡觉睡到自然醒。但在一整天的辛勤劳累后,每天我总是拖着疲惫的步子迈入家中,每晚又早早地进入梦乡。大清早有时真的很想在床上多躺一会儿,抑或是奢望着在地铁上能坐到个位子。虽然有时真的很累,但咬牙坚持,所有点点滴滴的付出都让我体会到在长大的同时也要学会付出。长大后不能再孩子气了,不能想怎么样就怎么样,长大后要学会适应,迎接每一个挑战。

单项选择题

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 shoots with organic nitrogen compounds. This comes in handy for the growth of buds in the early spring when leaves are not yet functioning. Once leaves begin photosynthesizing, they produce protein, but only mature leaves can "export" protein to the rest of the plant in the form of amino acids.

It can be inferred from the passage that, in the early spring, the buds of plants________.

A.export protein in the form of amino acids

B.do not require water

C.have begun photosynthesizing

D.obtain organic compounds from the root
