sensitivity to the sun. It causes a red itchy rash on your skin. Sometimes it happens if you take medicine and then are in the sun. Other people have that reaction to the sun all the time.

Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive.

Photosynthesis is the process that plant/tree makes their food in the presence of sunlight called as light reaction.
Chlorophyll present in the leaves absorb the sunlight in presence of water in the plant/tree and make food for the plant/tree. This reaction is called photosynthesis. (light reaction).
There is dark reaction too. Plant/tree can make their food in absence of sunlight that process called as dark reaction.
