Effect of Chemical Concentration on Photosynthesis Rate

Medium Data Representation Understanding Graphs And Tables

A laboratory performed an experiment to examine the effect of different concentrations of a chemical solution on the rate of photosynthesis in spinach leaves. The results over a 5-hour period were recorded in the table below:

Concentration (M)	Rate of Photosynthesis (mg O₂/hour)
0.1	2.0
0.2	4.5
0.3	7.5
0.4	6.0

Based on the data provided, what can be inferred about the relationship between the concentration of the chemical solution and the rate of photosynthesis in the spinach leaves?

The rate of photosynthesis consistently increases with higher concentrations.

There is an optimal concentration that maximizes the rate of photosynthesis.

Higher concentrations always lead to a decrease in photosynthesis.

There is no correlation between concentration and photosynthesis rate.
