Discover how green plants absorb light in their leaves and convert it to energy by photosynthesis carbon dioxide concentration and light intensity can affect the rate of photosynthesis investigating photosynthesis - gas exchange photosynthesis can be investigated to show gas exchange. // provide alternate content for browsers that do not support scripting // or for those that have scripting disabled this virtual experiments require adobe flash player to oppera. Essay sample on photosynthesis investigation topics specifically for you order now the equation for photosynthesis: this meant that the rate of photosynthesis increased as the light intensity increased this was because photosynthesis is a reaction. Factors affecting the rate of photosynthesis the term rate always involves time, so the rate of photosynthesis can be considered to be how fast photosynthesis takes place.
Plan i plan to investigate how light intensity affects the rate of photosynthesis in pondweed the rate of photosynthesis will be measured by the number of bubbles given off (considering that oxygen is produced as a waste gas during photosynthesis. The aim of this experiment is the effect of temperature on the rate of photosynthesis in elodea canadensis we will write a custom essay sample on investigating the rate of photosynthesis in specifically for you order now background knowledge: as level: from biology 1 (2000) jones, fosbery. Answer to exercise 2 - investigating photosynthesis in this exercise, you will design a study to investigate factors that may influence rates of photosynthesis. Start studying investigating the effect of different factors on the rate of photosynthesis learn vocabulary, terms, and more with flashcards, games, and other study tools. Investigating photosynthesis the production of oxygen by photosynthesis is most easily seen in water plants such as elodea and cabomba the number of bubbles released in a given time can be counted as a measure of the rate of photosynthesis.
What is a rate limiting factor what are the rate limiting factors in photosynthesis how do you test the effect of a factor on photosynthesis what are the. 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 in leaf disks teacher preparation and background information general information: photosynthesis is a process in which plants convert light energy create hypotheses about the effects of environmental variables on the rate of photosynthesis. The floating leaf disk assay for investigating photosynthesis introduction: trying to find a good, quantitative procedure that students can use for exploring photosynthesis is a challenge. The floating leaf disk assay for investigating photosynthesis the rate of photosynthesis can be measured by either the disappearance of substrate or the accumulation of product designing and conducting your investigation what factors affect the rate of photosynthesis in living plants.
This activity is a lab where students design an experiment to test the rate of photosynthesis students will analyze data,write a report using the scientific method, and apply results to current environmental issues. Ap biology investigation on photosynthesis includes background information and instructions for using spinach leaf disks, light, and baking soda to measure the rate of photosynthesis specific instructions are included for measuring the rate of photosynthesis in relation to light and carbon.
