Question

which function are essential for photosynthesis​

Answer 1

Answer :-

1) Presence of sunlight.

2) Presence of chlorophyll.

3) presence of CO2.

4) Constant temperature.

Explanation :-

Photosynthesis :- It is the catabolic process in which green plants make their own food in the presence of sunlight with the help of chlorophyll.

The reaction of photosynthesis is :-

$6CO_2 + 6H_2O + hv → C_6 H_12O_6 + 6 CO_2$

where hv is the sunlight.

Factors on which photosynthesis depends :-

• Presence of CO2. → Without CO2 plant cannot make their own food.

• Presence of water → The hydrolysis of water produces NADPH which gives oxygen and free electrons.

• Presence of chlorophyll → It absorb the sunlight.

• Temperature → It also affects the rate of photosynthesis. photosynthesis occurs maximum in normal temperature (25°c )
