Question

List the three events that occur during the process of photosynthesis. Explain the role of stomata in this process.??

​

Answer 1

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 2

Explanation:

Answer

Three major events occur in plant cells during photosynthesis:

«« absorption of light energy,

«« conversion of light energy into chemical energy, and

«« storage of chemical energy in sugars. Those three events occur in two distinct but interdependent sets of reactions.
