Photochemical reaction: a chemical reaction induced by electromagnetic radiations: ul- traviolet, visible, etc.) Thermal reaction: a chemical reaction induced by increasing the temperature (ex.: thermal dissociation, etc.)
A primary photochemical reaction is the immediate consequence of the absorption of light. Subsequent chemical changes are called secondary processes. http://edelsteincenter.files.wordpress.com/2010/07/photochemistry.pdf

ozone
photosynthesis ------------------------------------------- generically a "photochemical" reaction.
because,starch undergoes a photochemical reaction. So, with the passage of time it can under go to the photochemical reaction and starch wouldnot be starch but it might have changed in anyother product. so...we should use freshly prepared starch.

Because it depends upon light.
In photochemical reaction we have photons that passed to the surface starting photochemical reaction - producing some electrons. quantum yield=produced electrons/passed photons.
The energy in light
it happens in the thylakoids of a chloroplast.
