Answer:
your answer is here !
Explanation:
Three most important steps of photosynthesis are:-
Absorption of light energy by chlorophyll
Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen
Reduction of carbon dioxide to carbohydrates
Stomata are present in enormous amount over leafs, this tiny pores helps in the exchange of gaseous by photosynthesis. Since large amount of water can also be lost through these stomata, the plant closes these pores when it does not need carbon dioxide for photosynthesis, opening and closing of pours is regulated by guard cells, it swell up when water flows inside them, causing the stomata pore to open. Similarly the pore closes if the guard cells shrink.

Answer:
The three events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen. Role of stomata These help in the gaseous exchange between the plant and its atmosphere.
