The rate of phtosynthesis

This holds true for photosynthesis as well. However, you can probably think of several inaccuracies in this method. Medium Temperatures At medium temperatures, between 50 and 68 degrees Fahrenheit, or 10 and 20 degrees Celsius, the photosynthetic enzymes work at their optimum levels, so photosynthesis rates gauge high.

How to measure the rate of photosynthesis with temperature

Temperature The chemical reactions that combine carbon dioxide and water to produce glucose are controlled by enzymes. Photosynthesis is affected by light, temperature, water, and CO2. However, the light becomes a limiting factor in low intensity because no matter how much water or CO2 is present, without light photosynthesis cannot occur. Above a certain temperature about 45 degrees Celsius , the enzymes involved in the reaction begin to denature and, consequently, the rate of the reaction begins to drop sharply until it stops altogether. The proteins are folded into a very particular shape, and this allows them to bind efficiently to the molecules of interest. Photosynthesis uses maximum up to 1. Therefore, in this case, CO2 is the limiting factor. Learn more about Dark Reaction and Photorespiration in more detail here. Temperature It is commonly seen in all biological and biochemical processes that they occur best in a certain optimum range of temperature. How Photosynthesis Works Photosynthesis defines the process by which plants and some bacteria manufacture glucose. However, if the light intensity is increased above a certain threshold, the rate of photosynthesis will not increase because another factor such as temperature is limiting the rate of the reaction. Water Water is considered one of the most important factors affecting photosynthesis. This is because oxygen production and carbon dioxide uptake are affected by respiration as well as photosynthesis. However, light intensity can only increase up to a certain point before the rate of photosynthesis no longer increases. High Temperatures At temperatures above 68 degrees Fahrenheit, or 20 degrees Celsius, the rate of photosynthesis decreases because the enzymes do not work as efficiently at this temperature.

Photosynthesis is affected by light, temperature, water, and CO2. This would best be done with a reference colour chart to try to make the end-point less subjective. For plants inside a greenhouse, the installation of a greenhouse heater and thermostat prevents this from occurring.

factors affecting the rate of photosynthesis

Depending on the particular plant in question, set the greenhouse thermostat to a temperature within this range for best results. Measuring photosynthesis via the production of oxygen Oxygen can be measured by counting bubbles evolved from pondweed, or by using the Audus apparatus to measure the amount of gas evolved over a period of time.

At high temperatures, enzymes are denatured. It also shows that the rate at which photosynthesis levels out is dependent upon other factors—both plants in 0. Optimum photosynthetic rates lead to the removal of greater amounts of carbon dioxide from the local atmosphere, producing greater amounts of glucose.

Leaves with more chlorophyll are better able to absorb the light required for photosynthesis.
