BIOLOGY CLASS 28th APRIL 2021

 Green plants are autotrophic is means that they synthesis own organic food by the process of photosynthesis. 

PHOTOSYNTHESIS - :

Plant synthesize there food with the help of light which means sunlight. 

It is the important process by which green plants synthesize simple food like starch, carbohydrates and evolve molecular oxygen from simple organic substance like carbon dioxide and water with the help of light energy. 

                                     OR

The process of photosynthesis can be defined as the conversion of photonic energy (solar energy or radiant energy) into two chemical energy

1. locked in high energy bonds of carbohydrate.

2. By the green parts of plants. 

Photosynthesis is most important anabolic process

Metabolic have two types

1. Anabolic

It is a constructive process which was done by plants in photosynthesis.

2. Catabolic

It is a destructive process in which break down of food takes place which was done in Digestion.

Now, the most important anabolic process in nature for supplying food supply to biological world and purifying the atmospheric air by consuming Carbon dioxide and evolving oxygen.

        OR

The overall process simple chemical equation of photosynthesis is

6 co2 + 6 h2o gives c6h12o6 + 6 o2

THANK YOU so much
