photosynthesis in spinach leaves have an optimal temperature where it works best. The optimal temperature for the fastest rate of photosynthesis will fall between 2°C and 75°C, and more towards the 24°C water. The difference between the two temperatures will affect the amount of time it takes for the leaf disks to float. Light-saturated photosynthesis rate. was calculated as. + , and the quantum yield of photosynthesis. The treatments did not alter these features, but in the leaves under low irradiance, the palisade cells were more compact and contained more and greener chloroplasts (Figure 3(a)...

It shows how the amount of CO2 and light affect the rate of photosynthesis. Lines of best fit were drawn for each CO2 concentration to make up for any inaccuracy in any individual result. The line of best fit gives a good picture of how the overall rate of reaction is affected by the light and CO2.
The rate of photosynthesis will be measured through time by recording the number of minuets each spinach disk would rise up. This will be displayed in a chart which will be shown with the C02 or without C02.
Using the floating disk assay, your problem is to design and carry out an experiment to test the effect of a variable on the rate of photosynthesis. You chose which variable you will investigate. However, don’t choose the variable of leaf age. It was the variable investigated in the Photo Finish Lab.
How can you look at a landscape and tell whether a lot of photosynthesis usually happens there? Answer 2: So by level of light you probably mean light However, once the light intensity gets high enough, the rate won't increase anymore because there will other factors that are limiting the rate of...
The original purpose of this experiment was to see if the color of light affects the amount of oxygen that the elodea produced. The experimental results after 16 hours were that the red, blue and white light produced 1 ml of oxygen. The yellow light produced 0.5 ml of oxygen. The green light produced no measurable amount of oxygen.
Learning how light affects plant growth is the first step to becoming a better indoor or outdoor gardener. Check out this quick article for the inside scoop! A new question may be forming in your mind now that we're talking rainbows: does the color of light affect plant growth? It does indeed.
Mar 24, 2004 · 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.
3. How do you measure the rate of photosynthesis in Hydrilla sp.? By counting the number of gas bubbles released in five minutes. The light intensity increase, the rate of photosynthesis increase. Light Intensity Affecting the Rate of Photosynthesis.

Photosynthesis vs. Light Intensity [Source: Steucek and Hill, Note that the shape of this curve is not the expected curve that rises and levels off. This is because the times to float are the inverse of the rate of photosynthesis. Taking the

  • Experiment to show how the colour of light affects the rate of photosynthesis.
  • Constants: 50 Light intensity, full disolved co2, white light color. Your experiment should look something like this: The effect of temperature on photosynthetic rate of Elodea (pondweed). Related. 20. How does a plant grow before photosynthesis is possible? 6. Does the light color...
  • As carbon dioxide concentration increases, the rate of photosynthesis increases. At high concentrations, the rate of photosynthesis begins to level out due to factors not related to carbon dioxide concentration. One reason might be that some of the enzymes of photosynthesis are working at their maximum rate.

The green pigment involved in photosynthesis is chlorophyll. Chlorophyll is green in appearance because it absorbs red and blue light, making these colours unable to be seen. It is the reflection of the green light that reaches out eyes, giving chlorophyll a green colour.

Maximum light happens in summer and minimum occurs in winter. The more sunlight, the more food producing ability plants have through photosynthesis. Light quality is the color or wavelength. Research indicates that blue and red wavelengths lead to the best plant growth. So, does the color of light affect plant growth? (Make the hole large enough to get a patch of color you can really see.) If you move the card closer to the screen, the patches of light will eventually overlap and you will see the mixtures of each pair of colors. If you want to experiment further, find out what happens when you use different colors of paper or poster board for the screen.
that photosynthesis involves both light absorption and enzymatic reactions. Between 1883 and 1885, a German physiologist, T.W. Engelmann, in a remarkably simple experiment, demonstrated which colors of light are used in photosynthesis. The spectrum of visible light varies from violet to red, as can be The thoughts are that they had plenty of light and were not pressured to develop more efficient light gathering. That is, the light was not the limiting resource in photosynthesis for plants. That being said, there is some extension toward the middle of the spectrum with the beta carotene and other pigments .

As carbon dioxide concentration increases, the rate of photosynthesis increases. At high concentrations, the rate of photosynthesis begins to level out due to factors not related to carbon dioxide concentration. One reason might be that some of the enzymes of photosynthesis are working at their maximum rate.

For photosynthesis to transform light energy from the sun into chemical energy (bond energy) in plants, the pigment molecules absorb light to power the chemical reactions. Plant pigments are macromolecules produced by the plant, and these pigments absorb specified wavelengths of visible light to provide the energy required for photosynthesis.
