Question

explain photosynthesis

Answer 1

The 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.

Answer 2

$\textbf{Photosynthesis}$

It is the natural process by which green plants and some other organisms prepare their food (Glucose).

It occurs in Chloroplast.

$\textbf{Equation :}$

6CO2 + 6H2O -----› C6H12O6 + 6O2

===================================

$\textbf{Raw Materials}$

Carbon Dioxide (CO2) and Water (H2O) are the raw material of Photosynthesis.

Sunlight is need for the Photosynthesis.

Glucose (C6H12O6), Water (H2O) Oxygen (O2) are the products of Photosynthesis.

==================================

$\textbf{Mechanism or Steps of Photosynthesis}$

→ Light energy is converted into Chemical Energy and the Water moleculesplits into Hydrogen and Oxygen.

→ Light energy of sun is absorbed by Chlorophyll.

→ Carbon-dioxide is reduced to form Glucose. And Oxygen is released into the atmosphere.

==================================

$\textbf{Importance of Photosynthesis :}$

Photosynthesis is important because it produces oxygen as a bi-product which is necessary for living.

Also food is made by the help of this process (Photosynthesis) which is also important for living.

===================================

$\textbf{Light and Dark Reaction :}$

Light Reaction :- It depends upon light. In this ATP and NADPH are produced.

Dark Reaction :- It doesn't depends upon light. In this Glucose ia produced.
