उत्तर
(i) Release of oxygen during photosynthesis
(ii) The physiological process in question is photosynthesis. Photosynthesis occurs in green plants (autotrophs). It is the process by which plants prepare carbohydrates and oxygen in the presence of sunlight, carbon dioxide and chlorophyll.
(iii)
1: Gas/Oxygen
2: Hydrilla
(iv) 6CO2+12H2O `"Sunlight"/"Chlorophyll"` C6H12O6+6H2O+6O2↑
(v) The rate of bubbling will increase.

Higher Order Thinking Skill.
Imagine that student A studied the importance of certain factors in photosynthesis. He took a potted plant and kept it in dark for 24 hours. In the early hours of the next morning, he covered one of the leaves with dark paper in the centre only. Then he placed the plant in sunlight for a few hours and tested the leaf which was covered with black paper for starch.
- What aspect of photosynthesis was being investigated?
- Why was the plant kept in the dark before the experiment?
- How will you prove that starch is present in the leaves?
- Name the raw materials needed for photosynthesis.
Mesophyll contains chlorophyll.
