Answer 1

Photosynthesis is an example of a chemical reaction.

Further Explanation

Photosynthesis

• Photosynthesis is the process by which green plants make their own food using energy from sunlight, water and carbon (iv) oxide.
• Photosynthesis occurs during the day in organelles known as chloroplasts.
• Chloroplasts contains a special pigment known as chlorophyll which aids the process of photosynthesis by absorbing sunlight.
• Photosynthesis occurs in two stages;

Light dependent stage

• Light dependent stage is the first stage of photosynthesis which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
• During this stage energy from sunlight is absorbed by chlorophyll and is used to break down water molecules in a process called photolysis to hydrogen ions and oxygen. ATP and NADPH are generated during this process.
• Hydrogen ions are then taken to the next stage while oxygen gas is either used in cellular respiration or released to the atmosphere.

Light independent stage

• It is the second stage of photosynthesis that does not require sunlight. It occurs in the stroma part of the chloroplast and is also known as carbon dioxide fixation.
• During this stage hydrogen ions from the light dependent stage combines with carbon dioxide in the Calvin cycle to from simple sugars such as glucose and fructose.
• The simple sugars formed are either used to generate energy for the plant or stored in form of starch.

• Photosynthesis is an example of a chemical reaction in which reactants carbon dioxide and water combine in presence of sunlight to generate product simple sugars.

The overall chemical equation is;

6CO2 + 6H2O → C6H12O6 + 6O2

Answer 2

Answer : Photosynthesis is an example of a chemical reaction.

Explanation :

Photosynthesis : It is a type of chemical process which takes place in the plant cell. In photosynthesis process, the light energy converted into the chemical energy.

As plant needs carbon dioxide, water and light. During the photosynthesis, carbon dioxide, water and sunlight react to gives glucose, oxygen and water as a product.

The balanced reaction of photosynthesis will be,

$6CO_2+12H_2O\overset{sunlight}\rightarrow C_6H_{12}O_6+6O_2+6H_2O$

Hence, photosynthesis is an example of a chemical reaction.
