Recommended: The effect of light on photosynthesis

Conclusion
Temperature and light are the two main contributing factors to photosynthesis rate. So in theory as temperature increases and light increases so will the photosynthesis rate. This is because reactions occur when the plant enzymes collide and bind with a substrate. The increase in temperature would mean an increase in the kinetic energy of the plant enzymes meaning they would move faster, and therefore collide more frequently with the substrates, so as a result an increase of photosynthesis occurs. However when a system reaches a certain temperature, usually around 40° C, the plant enzymes become denatured, causing an immediate decrease in photosynthesis rate. The enzymes are denatured because higher temperatures cause the enzyme …show more content…

This suggests that the lights which produced heat are less suitable for use with the growth of these plants.
The hypothesis was that the heat producing bulbs would make the plants produce more oxygen as they would be photosynthesising more, however the results disprove this idea. A possible reason for this is that the plants used were both aquatic and so are more used to cooler temperatures. Therefore their optimum temperatures for photosynthesis would have been lower than the usual for land plants, suggesting that the warmer temperature reduced their efficiency. (“Aquatic Plants for Freshwater Aquariums”)
The results on the graphs are grouped in clusters, each cluster represents the result obtain with the different light bulbs. Each cluster is group relatively close together and there is little variation in the error bars suggesting that the results obtained are reliable. The light bulbs which produced less or no heat are clustered together and have higher oxygen concentrations, meaning they were more compatible for the …show more content…

It would be done by putting a plant in a closed system and measuring the fluctuations in the respiration rates and the oxygen production rates. It would be useful to see how light and temperature affect the plants. Also the knowledge could then be applied in the growth of crops in greenhouses to increase efficiency in yield production, and reduce the carbon dioxide production. Both of which would help reduce world hunger and reduce greenhouse gas emissions as carbon dioxide is a major contributor to greenhouse gas emissions (“Sources of Greenhouse Gas

The three things that can cause the enzyme to denature is a large change in pH level, High Temperature, and substrate concentration. According to our knowledge, we know that a large change in pH will cause instability in the protein structure thus resulting in denaturation of the enzyme. From the data, we can see that pH 3 (total:6.3) and 10 (total:6.2) were the slowest because pH 3 is probably the highest acid and pH 10 is the highest base. The highest acid or base pH represents a large change which would cause the enzyme to denature. The fastest pH was 6 (total:34.5), and it seems that there wasn’t a large change which resulted in a stable structure.

In Burns Bog and Watershed Park, the light was blocked at certain times because of the cover of the trees. Light intensity affects the rate of photosynthesis as with more sunlight, more carbon dioxide can be produced for the plants to grow. The types of vegetation is affected by light intensity as when the amount of sunlight decreases, the growth decreases as well. This is why SWMA has more grass plants such as, Aster and Colonial Bent Grass. According to the Spearman's Rank Correlation Coefficient, the correlation coefficient of light intensity and Aster is 0.4.

These findings show that the null hypothesis is rejected, and that there is a major difference between the observed and expected values. It is also observed that in the data in Figure 1.1, as the concentration of the NaHCO3 increases, the greater the production of oxygen. The highest photosynthetic rate is in at a 1.0% concentration of NaHCO3and the lowest in at a 0.1% concentration of NaHCO3. It is also important to note that the 0.4% concentration of NaHCO3 had a greater oxygen production than the 0.6% concentration of NaHCO3.

The most important result from this experiment is that it suggested that the increase of Carbon Dioxide, will drastically increase the growth mountain maple in the covered (from the sun) parts in a forest, in the meantime any increase in the temperature of the soil will nullify the increase of light, as we know is to be the main ingredient for photosynthesis. 5.

Especially since the experiment states that it was a healthy plant, whereas a yellowish, drooping malnourished plant would not be able to provide sufficient data. So for the time being it'll take in CO2 until it stops functioning without the sun. Tube C would also be yellow because there is no longer equilibrium once the plant runs out of initial energy from it's previous lit environment(before being used for the experiment). Tube D will not change because there is nothing with get the blue

Abstract This experiment showed that temperature, concentration and pH all affect the rate of enzyme reaction differently. Enzymes are very important in organisms and therefore understanding how and why they work the way they do in specific conditions is crucial. The results showed that an increase in temperature would also increase the reaction rate, until a temperature that was too high, where the enzymes began to denature and therefore the rate of reaction was slowed down. As concentration was increased, the reaction rate continued to increase.

The purpose of this lab was to measure the amount of CO2 gas given off by germinated peas under certain conditions of light. We conjectured that the more amount of light the peas are exposed to, the higher the respiration rate they will have. Our data supported this because it showed that the germinated peas that were exposed to light 24 hours before the experiment had a steeper slope (as seen in table 1), therefore having a greater respiration rate. The peas that were not exposed to any light 24 hours before the experiment had a reduced rate because of its lack of exposure to light. Both pea’s respiration rates showed that the more light the peas were exposed to, the greater respiration rate they would have (Figure 1).

Background Information: In this experiment I will be investigating the impact of light intensity on the rate of water uptake, due to transpiration, by attaching a shoot from a leafy plant in the capillary tube of a potometer, and then measuring how long it takes for a bubble to move a set distance. The faster the bubble moves, the greater the rate of transpiration. I will be placing one plant in an environment where it is exposed to high-light intensities, and another plant in an environment where it is exposed to low-light intensities. Transpiration is the process of the transport of water and nutrients up the the plant from the roots to the leaves.

Introduction Plants are a major necessity in the balance of nature, people’s lives, and our terrain. We may not realize it, but plants are the ultimate source of food for almost 95% of the world population so says the National Group of Food. It’s a fact that over 7,000 species of plants are being consumed today. Plants are one of the reasons that we get clean water; as they help regulate the water cycle.
