what is photosynthesis?Brefily explain the role of leaves in photosynthesis. Also write the chemical equation. ( long Q/A)
Answers
Answer:
Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive. Oh yes, we need the food as well!
We can write the overall reaction of this process as:
6H2O + 6CO2 ----------> C6H12O6+ 6O2
Definnition of Photosynthesis
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. It would be impossible to overestimate the importance of photosynthesis in the maintenance of life on Earth. If photosynthesis ceased, there would soon be little food or other organic matter on Earth. Most organisms would disappear, and in time Earth’s atmosphere would become nearly devoid of gaseous oxygen. The only organisms able to exist under such conditions would be the chemosynthetic bacteria, which can utilize the chemical energy of certain inorganic compounds and thus are not dependent on the conversion of light energy.
Chemical Equation
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
