Question

(Answer 10, 11, 12, 13, 14, and 15 on the basis of 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?
Which statement is correct?

• A. Photosynthesis occurs in animals
• B. Photosynthesis occurs in green plants
• C. Photosynthesis occurs in non green plants
• D. Photosynthesis occurs in fungus

Answer 1

The correct option is B

Photosynthesis occurs in green plants

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

1. Photosynthesis is the process involving the synthesis of organic food from inorganic substances with the help of chlorophyll in the presence of sunlight.
2. The leaves present on a plant appear green due to the presence of chlorophyll which is an essential component of photosynthesis.
3. Chlorophyll is the green pigment that plays a crucial role in trapping solar energy to convert it into chemical energy.
4. This chemical energy is used to generate glucose molecules which are the end product of the photosynthesis process.

The explanation for incorrect options:
Option A:

Animals have a heterotrophic mode of nutrition, they cannot produce their food by photosynthesis.
Option C:

Non-green plants lack the green photosynthetic pigment chlorophyll which is required for photosynthesis. Therefore, they can't produce their food.
Option D:
The fungus does not have chlorophyll thus, they are not photosynthetic.
Final answer: Photosynthesis occurs in green plants
