Maybe the plant is already a bit "exhausted" - try to take a different branch. Photosynthesis is basically a chemical reaction. With all chemical reactions, the higher the temperature, the faster the rate of reaction. Your experiment should look something like this: The effect of temperature on photosynthetic rate of Elodea (pondweed). June 19, 2016 Assignment Answers An investigation into the effects Temperature has on the Rate of Photosynthesis Aim: The aim of this experiment is to investigate the effect of various temperatures on the rate of photosynthesis by measuring the volume of oxygen produced by elodea. In corn which does not evolve CO 2 during illumination there was little effect of increasing temperature on the rate of apparent photosynthesis. We found that Synechococcus spp.
How does temperature affect the rate of photosynthesis? Or maybe it needs more time to get used to the new temperature. Why does temperature affect respiration rate of fish?
The different response to temperature of CO 2 evolution in light and in darkness support the earlier conclusion that these are 2 different processes.
A Biology project investing the effect temperature has on the rate of photosynthesis in plants. highlight how temperature affects the rate of photosynthesis at low temperatures (less than/equal to 30 degrees) - a general rule the trend: as long as water and carbon dioxide are sufficient, (+ temperature is the ONLY limiting factor), the rate of photosynthesis will increase as temperature increases It has long been recognized that C4 plant species have a higher temperature optimum for photosynthesis than C3 plants due to the operation of a CO 2-concentrating system that inhibits Rubisco oxygenase activity (Berry and Björkman, 1980; Edwards and Walker, 1983).In C3 plants, inhibition of net photosynthesis (Pn) at moderately high temperatures has usually been ascribed to … In this study, we develop a mechanistic understanding of how temperature affects growth and photosynthesis in 10 geographically and physiologically diverse strains of Synechococcus spp.
I assume you used Elodea canadensis for your test.
are able to regulate photochemistry over a range of temperatures by using state transitions and altering the abundance of photosynthetic proteins.
This is important because it means that the amount of dissolved oxygen ( DO ) available to organisms is directly related to water temperature . Temperature also affects the amount of gas that can be dissolved in a given amount of water. Like someone stated earlier, though, once you get above 90 degrees F, the rate of photosynthesis starts to decrease because the enzymes start breaking down (become denatured - a fancy way of saying "cooked").
