Answer:
Adenosine triphosphate, also known as ATP, is a molecule that carries energy within cells. It is the main energy currency of the cell, and it is an end product of the processes of photophosphorylation (adding a phosphate group to a molecule using energy from light), cellular respiration, and fermentation.
 It is made up of the molecule adenosine (which itself is made up of adenine and a ribose sugar) and three phosphate groups. It is soluble in water and has a high energy content due to having two phosphoanhydride bonds connecting the three phosphate groups
  Its main function is to store energy within the cell. ... ATP hydrolysis is an exotermic reaction, releasing energy which is used by the cell.sphate groups.

The set of Wavelength is absorbed by pigment. So in a typical leaf some pigment can’t be visible.
Explanation:
There are mainly three types of key pigments in photosynthesis.  These three key pigments are Chlorophyll a, Chlorophyll b, and β-carotene. Those set of wavelengths which is not absorbed by pigment and finally it is reflected and that reflected light is what we see as a color.
The reason behind color of plant looking green because it contains huge amount of chlorophyll a and b molecule. It reflects the green light.
