Listening to a variety of English accents and speech rates will also help you prepare for the exam. Good luck with your studies! 相关知识点: 试题来源: 解析 A) Absorbing sunlight. 在光合作用中,叶绿素的主要功能是吸收光能。以下是逐项分析:1. **选项A(吸收阳光)**:叶绿素作为光合色素,其核心作用...
Describe the properties of light. What part of the electromagnetic spectrum is used in photosynthesis? Why? Describe two practical uses for an artificial chemical that behaves like chlorophyll. Explain the value of each of the uses to society. ...
Photosynthesis is the process by which plants convert light energy, carbon dioxide, and water into glucose and oxygen using chlorophyll in chloroplasts. It is vital for plants to produce their own food (glucose), release oxygen, and sustain energy flow and gas balance in ecosystems. 1. **判...
Photosynthesis is the process used by plants, algae and somebacteriato turn sunlight into energy. The process chemically converts carbon dioxide (CO2) and water into food (sugars) andoxygen. The chemical reaction often relies on a pigment called chlorophyll, which gives plants their green color. ...
Photosynthesis: Photosynthesis is a biochemical process that is carried out by photoautotrophs to convert light energy into potential energy. It occurs in the chloroplast with the help of the photosynthetic pigment named chlorophyll (present in the thylakoid). Some examples of ...
What role does chlorophyll play in photosynthesis? A. It absorbs water. B. It absorbs carbon dioxide. C. It absorbs light energy. D. It releases oxygen. 相关知识点: 试题来源: 解析 C。解析:叶绿素在光合作用中吸收光能。A 选项吸收水的不是叶绿素;B 选项吸收二氧化碳的也不是叶绿素;D 选项释放...
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. What is chlorophyll?
During photosynthesis,chlorophyll takes in sunlight. This gives the plant energy. The leaves use the energy to mix CO, with water. This helps food production.In autumn, days become shorter and shorter.There is less sunlight for the plants. When winter comes, there is less water in the air...
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 ...
Leaves get their green color from chlorophyll, the chemical that's responsible for photosynthesis. 树叶是绿色通常是因为叶绿素这种物质,它有助于光合作用。 The chlorophyll in the leaves collects energy from the Sun in the form of sunlight and it converts this energy into sugar which is food for ...
