Enzymes do not perform well at low temperatures, but they also have an optimum temperature--the optimum temperature of photosynthesis illustrated by Professor van Resenburg--after which performance declines and, eventually, stops altogether.

However, for photosynthesis at temperatures above 40°C the rate slows down. This is because the rate of photosynthesis is slowing down because the temperature has reached its optimum and now increase in temperature has an effect on the rate of photosynthesis. growth and photosynthesis. • High temperature → More oxygen bubbles• High temperature increases: – Rate of chemical reactions – Metabolic activities in plant body – Rate of photosynthesis Secondary effects from climate warming could compound the direct effect of temperature on Synechococcus spp.

These differences in temperature do not affect the light reactions or the calvin cycle in leaves. Temperature. Temperature experiment .

By the middle of this century, sea surface warming is expected to lead to the expansion of permanently stratified, low-productivity waters by 4.0% in the northern hemisphere and 9.4% in the southern hemisphere ( Sarmiento et al., 2004 ).

There was no photosynthesis happening with the hot and cold water. To test the effects of increased seawater temperatures on macroalgae photosynthesis, three treatments of different temperatures above the natural seawater temperatures occurring in the seawater catchment area (~27°C) in March of 2012 were determined. Experiment to determine the amount of chlorophyll ‘a’, chlorophyll ‘b’ and total chlorophyll in a given plant tissue: 6. The bubbles produced are bubbles of oxygen. Factors affecting the rate of photosynthesis 2. Photosynthesis is an enzyme-dependent reaction, which explains why temperature exerts such strong effects on photosynthesis. 4.

The higher the temperature then typically the greater the rate of photosynthesis, photosynthesis is a chemical reaction and the rate of most chemical reactions increases with temperature.

At section B the line is becoming constant. Point X is the optimum temperature. In the experiment, it was found that 24 degrees celsius is around the optimal temperature for photosynthesis, which was the room temperature water. Experiment to show the effect of different wavelengths of light during the process of photosynthesis: 5. The effect of temperature on the photosynthetic rate of Chlamydomonas reinhardtii wild type (CC-1690 - wild type mt+ 21 gr) and mutant (CC-3913 - pf9-3-mt-) was studied in this experiment by the measurement of oxygen production under treatments of 15°C, 22°C, and 27°C. Experiment to demonstrate that carbon dioxide enters the leaf through the stomata: 7.
