Question

A 3. Mention the major events during photosynthesis?
Q4. Differentiate between light reaction and dark reaction?
Q5. What is photolysis of water?
Q6. What are stomata? Give two functions of stomata?
Q7. Name the site of light reaction and also mention the products formed during light reaction?
Q8. Dark reaction doesn't require light, then what is the source of energy for dark reactions to occur?

Answer 1

Answer:

1. photolysis is a process of spiltting of water molecule ...that is h2o reduces into H+ and OH- ....
2. stomata is a part of leaf which is covered with guard cells..
3. it helps in transpiration and gaseous exchange..
4. site for light reaction is granum ...products are assimilatory powers that is adp and nadph2

• events in photosynthesis are spiltting of water molecule
• conversion of solar energy into chemical energy.

reduction of carbon dioxide ....

source for dark reaction is assimilatory powers....

hope it helps u....

thank uu.

Answer 2

major events during photosynthesis are -

1 Absorption of light energy by chlorophyll

2 conversion of light energy to chemical energy and splitting of water molecule into hydrogen and oxygen

3 reduction of Co2 to carbohydrates
