The net effect is less photosynthesis how do greenhouses maximize photosynthesis the rate of photosynthesis does not necessarily increase. Ap biology unit 2, chapter 10 research question what factors affect the rate of photosynthesis in living leaves background you will design an experiment to. Three factors can limit the speed of photosynthesis - light intensity, carbon dioxide concentration and temperature if you plot the rate of photosynthesis against the levels of these three limiting factors, you get graphs like the ones above in practice, any one of these factors could limit the. Photosynthesis: photosynthesis from the air to make carbohydrates in photosynthesis over millions of years is being returned at an incredibly rapid rate.
Factors affecting the rate of photosynthesis is your design written in such a way that any grade 12 student could perform the lab. Identify another variable that might affect photosynthesis and design an experiment that uses leaf disks to test your variables on the rate of photosynthesis. Lab activity: measuring the rate of cell respiration and photosynthesis in a population of living organisms purpose: you will design an experiment using the scientiﬁc method to measure the rate of cell respiration or. “lab 5: photosynthesis: why do temperature and light intensity affect the rate of photosynthesis in plants” is one of 27 lab investigations for the high school student from the book, argument-driven inquiry in biology: lab investigations for grades 9-12.

A biology project investing the effect temperature has on the rate of photosynthesis in plants. Does light intensity affect the rate of photosynthesis in elodea plants hypothesis: yes, light intensity does affect the rate of photosynthesis experimental design. Class practical in this experiment the rate of photosynthesis is measured by counting the number of bubbles rising from the cut end of a piece of elodea or cabomba. Your goal is to find a way to consistently measure the rate of photosynthesis using any of the designs above part 2: conditions for photosynthesis 1 with the members of your group, brainstorm variables which may affect the rates of photosynthesis 2 form a hypothesis to test your variable 3 design an experiment to test your hypothesis. Affect the rate of photosynthesis in plants — both physical variables and biotic variables likewise, students consider variables that might affect the floating disk procedure itself these variables are compiled and categorized to serve as a guide for student questions and experimental design, as illustrated in table 1 table 1. Floating leaf disk photosynthesis lab design an experiment using the same set up to investigate a different variable in the rate of photosynthesis.
