In the experiment to observe oxygen is evolved during photosynthesis in the presence of light,is there any difference in the gas evolved between the plant in light and other in dark?
Answers
To prove that oxygen is produced during photosynthesis following steps need to do
Place water plant in a beaker containing pond water.
Cover the plant with short stemmed funnel.
Invert the test tube full of water and cover the stem of the funnel.
While placing the test tube, ensure that the level of the water in beaker is above the level of stem of funnel.
Expose the apparatus to the sunlight.
After few hours, gas bubbles will form and collect in the test tube.
Test the gas in the test tube.
A glowing splinter bursts into the flame shows the presence of oxygen.
Observation: Gas bubbles in a test tube.
Result: Presence of oxygen.
Conclusion: Formation of gas bubbles prove that oxygen is produced by the green plants during photosynthesis.
Concept Introduction:
Utilizing a process called photosynthesis, plants and other living things may transform sunlight into chemical energy that can then be released through cellular respiration to power their activities.
Explanation:
We have been given a question about photosynthesis.
We have to find the experiment to observe oxygen is evolved during photosynthesis in the presence of light.
The actions below must be taken in order to demonstrate that oxygen is created during photosynthesis. Put a water plant in a container filled with pond water. With a short-stemmed funnel, cover the plant. Place the water-filled test tube upside down and cover the funnel's stem. Make sure the water in the beaker is higher than the test tube's stem when you set it down. Place the device in direct sunlight. In the test tube, gas bubbles will emerge and gather after a short while. In the test tube, analyze the gas. The presence of oxygen is indicated by the flame bursting into a bright splinter.
Observation: Gas bubbles in a test tube.
Result: Presence of oxygen.
Conclusion: The formation of gas bubbles proves that oxygen is produced by green plants during photosynthesis.
Final Answer:
The final answer is the evolved gas is oxygen.
