解析 答案:Chlorophyll is a pigment found in the chloroplasts of plant cells that absorbs light energy and uses it to convert carbon dioxide and water into glucose and oxygen, which are the energy source and byproduct of photosynthesis, respectively....
In photosynthesis, the energy from sunlight is first ___ by chlorophyll. A. caught B. absorbed C. received D. got 相关知识点: 试题来源: 解析 B。解析:本题考查光合作用中关于能量吸收的英语表达。“absorb”有吸收(光、热等能量)的意思,在光合作用中叶绿素是吸收太阳光的能量,这是一个特定的科学...
The green pigment in plants that is essential for photosynthesis is ___. A. chlorophyll B. carotenoid C. xanthophyll D. anthocyanin 相关知识点: 试题来源: 解析 A。植物中的绿色色素叶绿素是光合作用必不可少的。类胡萝卜素、叶黄素、花青素都不是主要进行光合作用的色素。答案是 A。 反馈...
8. The inner part of leaf which was originally green (contained chlorophyll) turns blue-black on adding iodine solution showing that starch is present in this inner part of the leaf. From this observation we conclude that the photosynthesis to make starch takes place in the presence of chloroph...
The green pigment in plants that is essential for photosynthesis is ___. A. chlorophyll B. carotenoid C. anthocyanin D. xanthophyll 相关知识点: 试题来源: 解析 A。植物中对光合作用至关重要的绿色色素是叶绿素。选项 B 类胡萝卜素、选项 C 花青素、选项 D 叶黄素都不是主要进行光合作用的色素。反馈...
Do only plants photosynthesise? No! Plants, algae, and some types of bacteria use photosynthesis to create energy. A large percentage of the Earth’s oxygen comes fromphytoplanktonin the oceans, which contain chlorophyll and use photosynthesis to create energy. ...
Chlorophyll is the green photosynthetic pigment present in chloroplasts which provides the energy necessary for photosynthesis. The intense green color of chlorophyll is due to its strong absorbencies in the red and blue regions of the electromagnetic spectrum, and because of these absorbencies the ...
This stage takes place in the thylakoid membranes of chloroplasts. Light energy, usually from the sun, is absorbed by pigments like chlorophyll, which triggers a series of reactions. These reactions produce ATP (adenosine triphosphate) and NADPH, two energy-carrying molecules, as well as oxygen,...
Chlorophyll C. ATP and NADPH D. Oxygen 相关知识点: 试题来源: 解析 C。解析:在光合作用的暗反应中,ATP和NADPH是必需的,它们是光反应产生并为暗反应提供能量和还原剂的物质。选项A,暗反应不需要阳光直接参与。选项B,叶绿素主要参与光反应。选项D,氧气不是暗反应所必需的。
