Q2. Write the balanced chemical equation for the process of photosynthesis. How photosynthesis occurs in desert plants?
Answers
Answer:
- The balanced chemical equation for the process of photosynthesis:-
Carbon dioxide + Water ⇒ Glucose + Oxygen + Water.
6 CO2 + 6 H2O ⇒ C6H12O6 + 6O2 + H2O
- The stomata of desert plants are open at night. Desert plants absorb carbon dioxide and create an intermediate throughout the night. They then employ this stored carbon dioxide to produce photosynthesis throughout the day when the stomata are closed to minimize water loss.
Explanation:
- The balanced chemical equation for the process of photosynthesis:-
Carbon dioxide + Water ⇒ Glucose + Oxygen + Water.
6 CO2 + 6 H2O ⇒ C6H12O6 + 6O2 + H2O
Where:
CO2 = carbon dioxide
H2O = water
light is required
C6H12O6 = glucose
O2 = oxygen
Desert plants that live in semi-arid conditions fix atmospheric CO2 to generate malic acid in the dark. These plants store organic acid during the night so that it may be used during the day. This carbon fixation method is known as Crassulacean acid metabolism (CAM). CAM plants have fleshy or succulent stems, leaves, and petioles. There are fewer leaves, a thicker cuticle, and the stomata are depressed on them.
They have closed stomata during the day and open stomata at night. This helps the plants preserve water while also cutting off the supply of CO2, which is essential for photosynthesis.
They take in CO2 at night and store it in the form of malic acid, an intermediate product.
Deacidification occurs during the day in the presence of light when malic acid is decarboxylated to pyruvic acid by the malic enzyme and CO2 is released. In this process, one molecule of NADP+ is reduced.
The Krebs cycle can oxidize the pyruvic acid to CO2 or convert it back to phosphoenol pyruvic acid.
The C3 or Calvin cycle accepts CO2 produced by deacidification and fixes it as carbohydrate in the form of ribulose bisphosphate.
