Answer:
a basic particle representing a quantum of energy
Step-by-step explanation:
hey there,
< I'm not exactly sure if you're referring to a specific movie or not, but photons do have a lot to do with photosynthesis. Photons have one general definition but do mean something a little bit different in chemistry vs. biology. Here, I'm going to give you the chemistry meaning of a photon (it is the same with biology, just think of plants instead of electricity!):
A photon of light is emitted by an atom when an electron within the atom transitions to a lower energy level.
That definition has to do with electrons and orbitals, so I hope you already know what those are but if you don't, you can ask me! >
Hope this helped! Feel free to ask anything else.
