Well in order to start photosynthesis we will go through the light dependent reaction first.
This three products that are made by the reactants are energy known as ATP and also makes NADPH and oxygen.
=
Light- dependent reaction
In order to start this reaction you will need two two reactants which are water and sunlight
ATP
Oxygen
NADPH
This three reactants make this product called Glucose which is sugar that plants make to live.
ATP
+
light-independent reaction
NADPH
In order to do the light independent reaction the light dependent had to occurred first because two of their products are going to be use as reactants in this reaction
+
=
=
Carbon dioxide
The Glucose is finally made and this is what the plants will use to survive, this is the sugar they need.
That's crazy and really amazing.
The plants contain this type of pigment called chlorophyll that is located inside the chloroplast. This is the reason why most plants are green because they contain a pigment called chlorophyll.
