Why is photosynthesis described as a chemical reaction for kids?
Photosynthesis is a chemical reaction in which carbon dioxide and water combine to produce glucose and oxygen. Energy for this process is provided by light, which is absorbed by pigments, primarily chlorophyll. Chlorophyll is the pigment that gives plants their green color.
Is photosynthesis reaction a chemical reaction?
Carbohydrates are produced by the process of carbon assimilation which is carried on by the combination of water, carbon dioxide, by the application of external energy, light, and chlorophyll along with the involvement of oxygen. The complete chemical reaction is labelled as photosynthesis.
Why is photosynthesis a chemical reaction quizlet?
How is the process of photosynthesis considered a chemical equation? Photosynthesis begins with molecules of water and carbon dioxide and when light is added the molecules break apart to rearrange into new molecules of glucose and oxygen.
What kind of chemical reaction is photosynthesis?
Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun's electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant.
How do you explain chemical reactions to kids?
A chemical reaction is a process in which one or more substances are converted to one or more different substances. In the reaction, the atoms of the starting substances are rearranged, forming new substances that have different properties.
Why photosynthesis is regarded as a chemical change give two reason write chemical equation also?
Photosynthesis is a chemical change as it is the process through which light energy is converted into chemical energy by plants. ,As new chemical species are produced, thus, photosynthesis is simply a chemical transition. The equation for the same is Water + Carbon dioxide → Oxygen + Glucose.
What is the chemical reaction for photosynthesis quizlet?
Write the photosynthesis chemical equation. The balanced equation for photosynthesis is: 6CO2 + 6H2O + sunlight energy = C6H12O6 + 6O2 Photosynthesis can be represented using a chemical equation: Carbon dioxide + water + light energy gives a carbohydrate + oxygen. You just studied 22 terms!
What type of reaction is photosynthesis quizlet?
Photosynthesis is an anabolic reaction because it combines simple molecules into more complex molecules.
How do you describe chemical reactions?
chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
What is a chemical reaction easy definition?
Definition of chemical reaction : a chemical change that occurs when two or more substances combine to form a new substance.
Why is photosynthesis an example of a chemical reaction and why is it classified as endothermic?
Photosynthesis is considered an endothermic reaction, because during the process of photosynthesis, energy from the sun or sunlight is being absorbed. Any chemical reactions that absorb heat energy from the surroundings to form products is termed the endothermic reaction.
Which chemical equation describes the photosynthesis properly?
The chemical equation for photosynthesis is 6CO2+6H2O→C6H12O6+6O2.
Which of the following best describes the chemical equation for photosynthesis quizlet?
The balanced equation for photosynthesis is: 6CO2 + 6H2O + sunlight energy = C6H12O6 + 6O2 Photosynthesis can be represented using a chemical equation: Carbon dioxide + water + light energy gives a carbohydrate + oxygen.
Does photosynthesis use chemical energy?
What is photosynthesis? Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
What is the overall reaction for photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Why is photosynthesis considered as an endothermic reaction?
Photosynthesis is considered an endothermic reaction, because during the process of photosynthesis, energy from the sun or sunlight is being absorbed. Any chemical reactions that absorb heat energy from the surroundings to form products is termed the endothermic reaction.
What is a chemical reaction also called?
Processes involving the atomic nucleus are called nuclear reactions. The substances that participate in a chemical reaction are called reactants. The substances that are formed are called products. The products have different properties from the reactants. Also Known As: reaction, chemical change.
Which one chemical reaction occurs in photosynthesis?
6. Which one chemical reaction occurs during photosynthesis? explanation – the chemical reaction that occurs during photosynthesis means Carbon dioxide is reduced and water is oxidised .
What type of reaction is photosynthesis?
Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun's electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant.
Which chemical reaction best represent photosynthesis?
Photosynthesis is usually represented by the equation 6 CO2 + 6 H2O + light –> C6H12O6 + 6 O2. During this process, organisms such as plants go through the light-dependent and light-independent reactions to convert carbon dioxide and water into sugars and oxygen.
Which chemical reaction occurs during photosynthesis?
6. Which one chemical reaction occurs during photosynthesis? explanation – the chemical reaction that occurs during photosynthesis means Carbon dioxide is reduced and water is oxidised .
Which of the following best describes the chemical equation for photosynthesis?
The chemical equation for photosynthesis is 6CO2+6H2O→C6H12O6+6O2.
Why is photosynthesis referred to as endothermic while respiration as exothermic reaction?
As glucose is broken down into carbon dioxide, water, and ATP energy, the respiration reaction is exothermic. The photosynthesis reaction is endothermic because in the presence of sunlight and chlorophyll, carbon dioxide and water, or we can assume the heat is transformed into endothermic glucose reaction.
What type of chemical reaction is photosynthesis?
Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun's electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant.
What means chemical reaction?
A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. Substances are either chemical elements or compounds.
Which statement about photosynthesis is correct?
Answer: Plants get the energy they need for photosynthesis from sunlight.
