Let's start from the word itself "Photosynthesis".
If I Break the word Photosynthesis in two parts,
No.1 Photon,
The word "Photon" means particle of light derived from the Greek word "Phos" which also means light.
And,
No.2 "Synthesis",
The word "Synthesis" means to synthesize something out of various ingredients.
Combination of these two words Photon+Synthesis, that is photosynthesis, means synthesizing "something" with the use of direct sunlight, water and carbon dioxide.
This "something" here means food in the form of glucose,the source of energy.
The process of Photosynthesis is applicable only in the case of plants,algae and group of bacteria, called Cyanobacteria.And the must ingredients are direct sunlight, water and carbon dioxide.
Guys, you would agree with me
it's a miracle by mother nature !!
In case I am hungry I have to go in the kitchen, look for veggies and cook them to satisfy my need for energy required to continue with the daily routine.
On the other hand unlike us plants, algae and group of bacteria called cyanobacteria don't have to look for ingredients. Only with the use of ready and naturally abundant direct sunlight, water and carbon dioxide they manufacture their own food in the form of glucose with in their bodies and oxygen which is released in the atmosphere, in the end.This Oxygen released at the end of photosynthesis, used in the process of respiration by rest of all living organisms including us.
So, now i believe you have understood what Photosynthesis is all about.
Definition:
"Green plants, algae and a group of bacteria called cyanobacteria in the presence of direct sunlight, water and carbon dioxide synthesize glucose(food for energy) and oxygen(released in atmosphere)".
These self feeders are the most important part of the viscious food cycle.
We human beings consider ourselves as the epitome of evolution in every aspect but the truth is we and whole animal kingdom is inevitably dependent on plants for as an energy source, directly or indirectly.
I am quiet confident that from now onwards you will never forget the definition of photosynthesis and basic science behind it. Guys, I will love to hear from you.Your every feedback will help me give you a better scientific content each time.
To the point explanation.
