PHOTOSYNTHESIS Final Exam Questions and Graded Answers, 100 %
Guaranteed
What is the main factor that can limit the rate of photosynthesis? - Light intensity,
temperature, and carbon dioxide concentration can all limit the rate of photosynthesis.
How can greenhouses enhance the rate of photosynthesis? - By controlling lighting,
temperature, and carbon dioxide levels, farmers can increase crop growth rates.
What is the independent variable in the experiment measuring photosynthesis? - Light
intensity, which is manipulated by changing the distance from the light source.
What is the dependent variable in the photosynthesis experiment? - The number of bubbles
of gas produced by the pondweed in one minute.
What is the control variable in the photosynthesis experiment? - The piece of pondweed,
temperature, and concentration of carbon dioxide must be kept constant.
What is the method to measure the rate of photosynthesis using pondweed? - Place
pondweed in a beaker, shine a light at it, and count the oxygen bubbles produced in one
minute.
What is the inverse square law in relation to light intensity? - Doubling the distance from the
light source reduces light intensity by a quarter.
What is the green pigment essential for photosynthesis? - Chlorophyll.
What do plants produce during photosynthesis that is used for energy? - Glucose.
What are some products that glucose can be converted into by plants? - Insoluble starch, fat
or oil, cellulose, and proteins.
