light intensity photosynthesis results

2. In most cases, the more light the faster photosynthesis occurs. Show More. For maximum photosynthesis, and therefore plant growth, common agriculture practices incorporate techniques to remove limiting factors. Koz 8 Analysis: If the distance between the plant and source increases, then the light intensity decreases. The aim of my experiment is to find out how light intensity affects the rate of photosynthesis. 0 14 13 15 14100 0. That mean the rate of photosynthesis also decreases in this graph. 3 Students should describe a procedure in which light intensity is varied but temperature is controlled. After each exposure, the cuvettes were placed in a spectrophotometer set at 621 nm and the absorbance of DCPIP was measured. As the light intensity decreased, the contents of chlorophyll a (Chl a), chlorophyll b (Chl b) and total chlorophyll (Chl a + b) all increased. When the light intensity is increased, the rate of bubble production should increase. Calculate the mean results for each colour of filter. However, at some point there's a limit that the rate of photosynthesis cannot increase above. Results. This study was undertaken to determine the relationship between of light intensity and rate of photosynthesis in spinach leaves. 0 23 23 21 2260 1. Results Distance (cm) Light Intensity (Arb Units) Amount Of Bubbles (Per min) Average 20 4. This implies that the net rate of photosynthesis was greater than the net rate of respiration. How to increase brand awareness through consistency; Dec. 11, 2020. Light intensity has a very large effect on the rate of photosynthesis. Light Intensity and the Rate of Photosynthesis. Photosynthesis is one of the most remarkable biochemical processes found on Earth and allows plants to use sunlight to make food from water and carbon dioxide. The number of light photons hitting the chlorophyll pigments increase as the light intensity rises. Related. Therefore, a sensible results table has been prepared, to share with the students. 4. A change of light intensity would result in a change of photosynthesis rate. 8 22 15 17 1880 1. However, the Chl a/b ratio gradually decreased. Therefore, there is less H^+ ions being pumped which results in the slower rate for photosynthesis. The results showed that (1) L. litseifolius is a typical heliophyte. Discuss the results shown in the graph. Light intensity. The reason that light intensity does affect the rate of photosynthesis is because as light, and therefore energy, falls on the chloroplasts in a leaf, it is trapped by the chlorophyll, which then makes the energy available for chemical reactions in the plant. As light intensity increases, more ATP and NADPH are created, thus increasing the photosynthetic rate. From the equation above, O_2 is a product from the process of photosynthesis. Plot a graph to show the mean rate of photosynthesis for each type of filter. ... rate of photosynthesis lab results. In this experiment a 100 Watt bulb was used. This in turn increases the rate of photosynthesis. 2 Carbon dioxide will have no effect, because it is not involved in the light-dependent reactions. For this experiment, DCPIP was added to cuvettes with spinach chloroplasts, which were exposed to an incandescent light at different distances for different intervals of time. a Rinse 6 translucent bottles with hydrogencarbonate indicator solution. This is because light effects the rate of photosynthesis. I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion, so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. 2), we want to determine the intensity and distance from light affect the rate of photosynthesis in aquatic plant because the plant itself needs more water to grow. identify the inverse relationship between Light intensity and distance of lamp from the … (this is where you should use your results and scientific knowledge) Ultimately, the higher the light intensity the less time it takes for the indicator to turn purple.
