LIGHT REACTION
Light reaction is the stage of photosynthesis which occurs only in the presence of sunlight and it is dependent on the light to perform its work. it takes place in the grana thylakoid membrane of the chloroplast. the grana thylakoid is responsible for trapping the solar energy for photosynthesis.
DARK REACTION
Dark reaction is the stage of photosynthesis which occurs in the presence or absence of the light. It is not dependent on light to perform its reaction. It takes place in the Stroma of the chloroplast. The stroma is responsible for enzymatic reaction to synthesise of glucose to form starch.

Answer:
Difference between light phase and dark phase.
i) Light phase -
- it depend on light
- oxygen is evolved
- occurs in thylakoid membrane
- temperature has little effect over it
- it produces ATP
ii) Dark phase -
- it did not require light
- Glucose is the end product
- it is influenced by temperature
- it consumes Atp
- it occurs in matrix of chloroplasts
