Question

Three Anacharis plants were placed inside inverted test tubes filled with water. One test tube

was exposed to low light, another to medium light, and another was exposed to high light. The
table provided shows the results of this experiment. Notice that more oxygen was produced by
the Anacharis in high light.

15 0.4 0.8 0.9
30 1.2 1.7 1.8
45 1.4 2.0 2.5
60 1.8 2.2 3.2
Based on the information provided, what is the difference in volume (in mL) of oxygen
produced between the low-light and high-light plants after 45 minutes?

Answer 1

Light plays an important part in photosynthesis.

Step-by-step explanation:

This is true because with low light, it shows that the Anacharis plant produced a low amount of oxygen. In high light, the oxygen produced went up alot. This shows that light is very important in photosynthesis.
