The diagram given below represents an experiment to demonstrate a physiological process taking place in green plants. Answer the questions that follows.

(a) Label the parts A and B in the given figure.

(b) Name the physiological process being demonstrated.

(c) How could the rate of photosynthesis be increased in the given setup?

(a) Parts A and B are:

• A → Oxygen
• B → Aquatic plant / Hydrilla

(b) Photosynthesis.

(c) Rate of photosynthesis can be increased by adding a pinch of NaHCO₃, because it releases CO₂ in water.
