Question

O² is produced in photosynthesis in presence of light​

Answer 1

Answer:

INTRODUCTION:The end products of photosynthesis are Oxygen(O2),water and starch.So one of the end products is oxygen ,which is proved by this experiment. ... RESULT:By this experiment, we proved that oxygen is produced during photosynthesis in the presence of sunlight

Answer 2

TRUE

Explanation

ExplanationThe following experiment shows that oxygen is produced in photosynthesis in presence of light:-

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.
