Why should the level of photosynthesis increase because sodium bicarbonate was added to the water? A2. (ii) Hydrilla plant twigs. 3. Problems with creating sodium hydroxide from sodium (hydrogen) carbonate. If bubbles fail to appear, cut off more of the stem and recrush. Place a 40 watt lamp 5 cm from the plant. For demonstration of photosynthesis experiments, usually aquatic plant Hydrilla is used , not any terrestrial plant , why ? (ii) Potassium hydroxide absorbs CO 2 from the surrounding. To test that oxygen is evolved during photosynthesis few fresh Hydrilla plants in a glass beaker filled with water. The equation for photosynthesis is as follows: Carbon dioxide + water ->glucose + oxygen. Plants use the same visible light spectrum as humans (wavelengths between 400 and 700 nanometers). Experiment. (iv) Incense stick PREVIOUSLY ASKED QUESTIONS 1 Mark Questions 1. Procedure for the experiment Take a beaker and fill 3/4ths of it with pond water. 1 decade ago. Pour equal amounts of the solution (20 mL each) in four large test tubes labeled A to D. 2. Answer 2. (TS: Mar 2015) A: 2. Pond water is used so that plant gets Co2 dissolved in water. Sodium hydrogen bicarbonate was used in this experiment to supply carbon dioxide to the pineapple leaf discs to perform photosynthesis. Place the tube in a beaker of fresh water. A: (i) The given apparatus is used to prove that O 2 is released during photosynthesis. The teacher can now review what a hypothesis is and how to write a specific, testable hypothesis.
