Answer 1

Hey there! here is ur answer-

Photosynthesis is the process by which green plants turn carbon dioxide and water into food using energy from sunlight.

*HopE* it Helps :-)

Answer 2

$\huge\mathfrak{Photosynthesis...}$

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.

$\textbf{Mechanism of Photosynthesis :}$

→ 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.
