long answer type questions.

Q.1 what is photosynthesis?
Q.2 Explain the mechanism of photosynthesis.

Answer 1

(1) Photosynthesis=> The process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms.

(2) Three steps mechanism of photosynthesis are:-

(i) The convert light energy into chemical energy and spliting water molecules into hydrogen and oxygen.

(ii) The reduction of CO2 to carbohydrates.

(iii) The formation of ATP and NADPH2.

Answer 2

HEY!!

✴The process of photosynthesis occurs in two phases. Those are the following :-

1) Light reaction
2) Dark reaction

LIGHT REACTION

✔This type of reaction takes place in the presence of light.
✔Light energy is absorbed by chlorophyll molecules and is utilized for splitting water molecules into hydrogen and oxygen.


DARK REACTION

✔This type of reactions does not need direct light and occurs in the stroma of chloroplasts.
✔ During this phase, ATP and  NaDPh2 (formed during light reactions) are utilized for the reduction of  CO2 into carbohydrates.
