What is photosynthesis?write the reaction that takes place during photosynthesis
Answers
he process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
Photosynthesis can be represented using a chemical equation.
The overall balanced equation is...
6CO2 + 6H2O ------> C6H12O6 + 6O2
Sunlight energy
Where: CO2 = carbon dioxide
H2O = water
Light energy is required
C6H12O6 = glucose
O2 = oxygen
Plants do need food for their survival and they would not wait or depend on others to provide them with food. There is a particular mechanism in plants with which they prepare their food. This mechanism is known as Photosynthesis.
Photosynthesis is a biological process used by plants to prepare food with the help of sunlight water and carbon dioxide. The name photosynthesis is derived from the Greek word ”Photo” meaning light and “Synthesis” meaning connecting together. This means combining together with the help of light energy.
This process is also used by algae and several bacteria to convert solar energy into chemical energy. Oxygen is liberated as a by-product, and light is considered as the major factor to complete the process of photosynthesis. This process occurs usually when plants use light energy to convert carbon dioxide and water into glucose and oxygen gas. Leaves are made up of small cells which have a tiny structure known as chloroplasts. Each chloroplast contains a green colored pigment called chlorophyll. Light energy is absorbed by chlorophyll molecules whereas carbon dioxide (CO2) and oxygen (O2) enter through the tiny pores of stomata located in the epidermis of leaves.
Oxygen is considered one of the most important by-products of this process on which most of the living organism depend upon. Glucose/Sugar is a form of carbohydrates that is processed during the process of photosynthesis. It is commonly used by green plants in the form of an energy source to produce leaves, fruits, flowers, and seeds. The glucose molecules then combine with each other to develop more complex carbohydrates like cellulose and starch. The cellulose is considered as the structural material that is used in plant cell walls. The overall reaction of photosynthesis process is:
6CO2 + 6H2O —-> C6H12O6+6O2
