Detailed explanation-1: -In this question, the independent variable is the air temperature while the dependent variable is the rate of photosynthesis.
Detailed explanation-2: -Independent variable-the light intensity (how close the light is). Dependant variable-the number of oxygen bubbles given off (the rate of photosynthesis).
Detailed explanation-3: -Students in a biology class conduct an experiment to determine the effect of temperature on the rate of photosynthesis in a plant. They place an Elodea plant into a test tube filled with water. Then, the students place the test tube under the light and slowly increase the temperature of the water.
Detailed explanation-4: -Students place a leaf in a clear cup of water. Then, they place the other leaf in the other cup of water. After about 20 minutes, you will see tiny bubbles begin to form on the edges of the leaf. Students should check the cups every 30 minutes and record changes to both cups on their lab sheets. 14-Mar-2022
