Represent the equation of photosynthesis. Explain the steps involved in photosynthesis. In which way are the steps of photosynthesis different in desert plants?

(N/A) The chemical equation for photosynthesis is: $6CO_2 + 6H_2O \xrightarrow[\text{Chlorophyll}]{\text{Sunlight}} C_6H_{12}O_6 + 6O_2$.
The three main events that occur during photosynthesis are:
$(i)$ Absorption of light energy by chlorophyll.
$(ii)$ Conversion of light energy into chemical energy and the splitting of water molecules into hydrogen and oxygen.
$(iii)$ Reduction of $CO_2$ into carbohydrates.
In desert plants,the process is adapted to conserve water. They take up $CO_2$ at night and prepare an intermediate product. During the day,when chlorophyll absorbs sunlight,this energy is used to act upon the intermediate product to synthesize carbohydrates.
