NEET Biology question

In an experiment demonstrating the evolution of oxygen in *Hydrilla*, sodium bicarbonate is added to the water in the experimental set-up. What would happen if all other conditions are favourable?

(A)Amount of oxygen evolved decreases as carbon dioxide in water is absorbed by sodium bicarbonate
(B)Amount of oxygen evolved increases as the availability of carbon dioxide increasesCorrect
(C)Amount of oxygen evolved decreases as the availability of carbon dioxide increases
(D)Amount of oxygen evolved increases as carbon dioxide in water is absorbed by sodium bicarbonate

Answer: (B)

Solution

Sodium bicarbonate dissociates in water to release additional CO2, increasing the CO2 available for photosynthesis. Since CO2 is typically
