Design an experiment to investigate how light intensity affects the rate of photosynthesis in aquatic plants. Describe the materials and methods you would use.

• Use a light meter, aquatic plants, and a stopwatch. Measure the rate of oxygen production at different light intensities.

• Use a thermometer, aquatic plants, and a stopwatch. Measure the rate of oxygen production at different temperatures.

• Use a pH meter, aquatic plants, and a stopwatch. Measure the rate of oxygen production at different pH levels.

• Use a balance, aquatic plants, and a stopwatch. Measure the rate of oxygen production at different weights.

How does temperature affects photosynthesis rate?

• As temperature increases, photosynthesis rate also increases.

• As temperature decreases, photosynthesis rate also decreases.

• Plants cannot photosynthesis if the temperature is too cold or too hot. 

• All of the statements are true.
