Question

Hon placed aquatic plants in several test tubes that were filled with water. Then, he placed half of the test tubes in a dark closet and the other half in a well-lit room. When he recorded his data, some of the plants had formed many small bubbles on the leaves, and some did not. Which describes what Hon most likely observed and the reason for these results?

Answer 1

The plants in the light formed bubbles because they released oxygen gas.

Explanation: simplified answer i hope this helps :)))

Answer 2

These bubbles on the leaves represent oxygen molecules. Oxygen is released in light-dependent reactions of photosynthesis and it is expected for bubbles to be found only of the leaves on those plants that were in a well-lit room.
