In the 1700s a scientist named Joseph Priestley discovered that when he placed a jar over a candle, the flame soon went out. However, if he placed a live plant under the jar with the candle, the flame did not go out. Use what you have learned about photosynthesis to explain Priestley's results.

In need help rlly fast!
