Question

what is photosynthesis​

Answer 1

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Answer 2

Answer: Photosynthesis is defined as the process, utilized by green plants and photosynthetic bacteria, where electromagnetic radiation is converted into chemical energy and uses light energy to convert carbon dioxide and water into carbohydrates and oxygen.

Equation:

Carbon dioxide + Water  + solar energy → Glucose + Oxygen

6CO2 + 6H2O  +  solar energy   →   C6H12O6 + 6O2

Carbon dioxide + Water  + solar energy → Glucose + Oxygen + Water

6CO2 + 12H2O+ solar energy    →    C6H12O6 + 6O2 + 6H2O

CO2 + 2H2S + light energy   →    (CH2O)  + H2O  + 2S

Process step by step:

• The carbohydrates formed from photosynthesis provide not only the necessary energy form the energy transfer within ecosystems, but also the carbon molecules to make a wide array of biomolecules.
• Photosynthesis is a light-driven oxidation-reduction reaction where the energy from the light is used to oxidize water, releasing oxygen gas and hydrogen ions, followed by the transfer of electrons to carbon dioxide, reducing it to organic molecules.
• Photosynthetic organisms are called autotrophs because they can synthesize chemical fuels such as glucose from carbon dioxide and water by utilizing sunlight as an energy source.
• Other organisms that obtain energy from other organisms also ultimately depend on autotrophs for energy.
• One of the essential requirements for photosynthesis is the green pigment ‘chlorophyll’ which is present in the chloroplasts of green plants and some bacteria.
• The pigment is essential for ‘capturing’ sunlight which then drives the overall process of photosynthesis.
