Question

(Answer 10, 11, 12, 13, 14, and 15 based on the following given data)
A Hydrilla plant is kept in a beaker containing water. It is converted with an inverted glass funnel and a test tube. The whole experiment is put in sunlight. It is found that the level of water is coming down and gas accumulates at the upper end of the test tube. The whole experiment is conducted in red, blue, and green light. After some time some amount of sodium bicarbonate is added to the beaker. Will these modifications affect the experiments in any way?

If 50% leaves of Hydrilla are removed, the rate of photosynthesis will be

• A. Less, but total photosynthesis will be more
• B. Less, and total photosynthesis will also be less
• C. More, but total photosynthesis will be less
• D. More, but total photosynthesis will also be more

Answer 1

The correct option is C

More, but total photosynthesis will be less

The correct option is C:
The explanation for the correct option:

1. Photosynthesis is the process that involves the synthesis of organic food materials from inorganic raw materials such as carbon dioxide and water in the presence of sunlight
2. The rate of photosynthesis will increase due to the increase in the amount of carbon dioxide around the surroundings.
3. When half of the leaves are removed from the Hydrilla plant, available carbon dioxide concentration increases for each leaf.
4. Therefore, the rate of photosynthesis increases due to the increase the concentration of carbon dioxide.

Final answer: If 50% leaves of Hydrilla are removed, the rate of photosynthesis will be increasing.
