Photosynthesis in plants mainly takes place in _. A. roots B. leaves C. stems D. flowers 相关知识点: 试题来源: 解析 B。解析:植物的光合作用主要在叶子中进行。选项A“roots”是根,根主要是吸收水分和养分,与光合作用关系不大;选项C“stems”是茎,茎主要起到支撑和运输的作用,不是光合作用的主要...
Photosynthesis in plants helps keep the balance of gases in the atmosphere. Which gas is mainly related to this balance in the process of photosynthesis? A. Hydrogen B. Oxygen C. Helium D. Argon 相关知识点: 试题来源: 解析 B。解析:植物的光合作用主要是吸收二氧化碳释放氧气,从而保持大气中气体...
Photosynthesis in plants Photosynthesis is the process by which plants produce food using light, water and carbon dioxide. It is a complex process that is essential for the survival of plants. Understanding how photosynthesis works can help us appreciate the importance of plants in our everyday ...
Studies of other higher plants have shown that alanine is metabolically related to 3-phosphoglyceric acid by a distinctive isotope distribution in which C1 ≥ C2 = C3; the reasonable assumption has been that these 3-carbon metabolites constitute the major precursors of the tricarboxylic acid cycle ...
Influence of Altitudinal Variation on the Content of Phenolic Compounds in Wild Populations of Calluna vulgaris, Sambucus nigra, and Vaccinium myrtillus This study deals with the effect of altitudinal variation on the content of phenolic compounds in three traditional herbal plants, which are also consu...
Photosynthesis in plants helps to keep the balance of gases in the ecosystem. Which gases are mainly involved? A. Oxygen and nitrogen B. Carbon dioxide and oxygen C. Carbon dioxide and hydrogen D. Oxygen and helium 相关知识点: 试题来源: ...
A. Root B. Stem C. Leaf D. Flower 相关知识点: 试题来源: 解析 C。解析:“photosynthesis”是光合作用的意思。在植物中,叶子(leaf)主要进行光合作用。根(root)主要起固定和吸收水分、养分的作用;茎(stem)起支撑和运输作用;花(flower)主要用于繁殖。反馈 收藏 ...
Human activity in the last 200 years has led to a marked increase in the level of C02 in the atmosphere. Plants sense increases in C02 levels and initially respond with an increase in photosynthetic rate, which may then slow as the plant adapts. This increase in photosynthetic rate may accou...
In natural habitats, plants frequently experience rapid changes in the intensity of sunlight. To cope with these changes and maximize growth, plants adjust photosynthetic light utilization in electron transport and photoprotective mechanisms. This involv
a保护好现有森林,大力植树造林,使大气中的二氧化碳通过植物光合作用转化为营养物质 Protects the existing forest, the vigorously afforestation, causes in atmospheric the carbon dioxide to transform through the plant photosynthesis as the nutrients[translate]...
