FAQs on Priestley & Ingenhousz experiments Video Lecture - NEET

1. What were the main discoveries of Priestley regarding photosynthesis?

Ans.Priestley discovered that plants release oxygen during the process of photosynthesis. He conducted experiments with a candle and a mouse in a sealed jar, finding that the mouse survived longer when a plant was present, indicating that the plant produced a substance that supported life, which we now know is oxygen.

2. How did Ingenhousz contribute to our understanding of photosynthesis?

Ans.Ingenhousz built upon Priestley's work by showing that light is essential for photosynthesis. He demonstrated that plants only produce oxygen in the presence of light, conducting experiments with aquatic plants and observing oxygen bubbles only when exposed to sunlight.

3. What experimental methods did Priestley use in his research?

Ans.Priestley used a variety of simple experiments, including placing a candle in a sealed jar to observe its extinguishment due to oxygen depletion, and then adding a plant to the jar to see the effect on the candle and mouse, leading to the conclusion that plants produce oxygen.

4. Why is the work of Priestley and Ingenhousz important for NEET students?

Ans.The work of Priestley and Ingenhousz is crucial for NEET students as it lays the foundation for understanding photosynthesis, a key biological process. Their experiments illustrate the relationship between plants, light, and oxygen, concepts that are often tested in biology exams.

5. What is the significance of light in photosynthesis as discovered by Ingenhousz?

Ans.Ingenhousz's experiments highlighted that light is a critical factor in photosynthesis, as plants only produce oxygen when exposed to light. This discovery is significant as it underscores the importance of sunlight for plant growth and energy production, which is essential knowledge for biology students.
