Question

Explain the process of photosynthesis with an equation

Answer 1

Equation ☝☝

meaning

photo means light and synthesis means to produce food. It means the process from which plants synthesis their own food in presence of food is known as photosynthesis.

Answer 2

ANSWER :

$\huge{\boxed{\mathcal{PHOTOSYNTHESIS}}}$

• " Photosynthesis " is a process in which green plants use sunlight , chlorophyll, carbon dioxide and water to synthesise organic food in the form of carbohydrates.

• EQUATION : 6CO₂ + 6H₂O + light energy = C₆H₁₂O₆ + 6O₂.

      → It occurs in two stages :

• LIGHT REACTION : During this reaction, Adenosine triphosphate and Nicotinamide adenine dinucleotide phosphate are generated. This step is light dependent.

• DARK REACTION : It is not dependent on light. During this reaction, CO₂   is reduced to carbohydrate. Source of energy is ATP and NADPH.

   ⇒ THE THREE EVENTS THAT OCCURS DURING THE  

        PROCESS OF PHOTOSYNTHESIS ARE :

     1. Absorption of light energy by the green pigment

       chlorophyll.

     2. Conversion of light energy into chemical energy and the  

     splitting of water molecule into hydrogen and oxygen.

     3. Reduction of carbon dioxide into carbohydrate.
