Question 9
Donny conducts the experiment in the laboratory. He grows corn plants in two different environments. He sets up the plant A in an environment with low CO2 and plant B in a high CO2. He writes the result of his experiment as shown in a table below.
| Times (week) | Growth rates (cm) (low CO2) | Growth rates (cm) (high CO2) |
| --- | --- | --- |
| 1 | 28 | 28 |
| 2 | 115 | 120 |
| 3 | 363 | 466 |
| 4 | 700 | 885 |
| 5 | 598 | 889 |
| 6 | 492 | 765 |
A. Change the table above into a graph. Time on the horizontal axis and growth rates in the vertical axis
B. How does carbon dioxide influence growth of the corn plants?
C. Which plants has a higher growth rate?
