Energy, Plants & Man 1 As the light intensity increases, the rate of photosynthesis increases. 2  However, the rate will not increase beyond a certain level of light intensity. 3  At high light intensities the rate becomes constant, even with further increases in light intensity, there are no increases in the rate.

What is Light Intensity, Effects on Plant GrowthBen G. Bareja Apr. 2011 Light intensity or light quantity refers to the total amount of light that plants receive. It is also described as the degree of brightness that a plant is exposed to. In contrast to light quality, the description of the intensity of light does not consider wavelength or color.The intensity of light is usually measured by the units lux (lx) and footcandle (fc).t is also described as the degree of brightness that a plant is exposed to. In contrast to light quality, the description of the intensity of light does not consider wavelength or color. The intensity of light is usually measured by the units lux (lx) and footcandle (fc).

- Blackman measured photosynthesis rates under differing light intensities, CO 2 concentrations, and temperatures. As this graph shows, light is the limiting factor at low light intensities, while temperature and CO 2 concentration are the limiting factors at higher light intensities.

How does a greenhouse speed up the rate of photosynthesis? A greenhouse dosn't speed up the rate of photosynthesis. what a greenhouse does, is it uses solar energy to keep the air inside the greenhouse at a higher temperature, so in colder locations, the plants inside will be in a more tropical environment, so they will be more efficient.

#105 Limiting factors in photosynthesis Paraffin lamps have traditionally been used in greenhouses. Their use increases the rate of photosynthesis because as well as the light generated from the lamps, the burning paraffin produces heat and carbon dioxide too.

Effect of temperature and light on the growth of algae species: A review The growth rate of S. costatum increased with the increasing light intensity from 20 to 40 µmol m −2 s −1. The highest growth rate of S. costatum is 0.3006 d −1 at 50 µmol m −2 s −1 [28] . The growth rate of algae is highly dependent upon rate of photosynthesis.ffects of light intensity and three LED monochromatic lights (blue, green, and red) on the growth of S. costatum, a marine species are investigated in batch culture conditions. Seven light intensities (20, 30, 40, 45, 50, 60 and 80 μmol m −2 s −1) are used to evaluate the specific growth rate.

Here a rise in light intensity has no affect on the rate of photosynthesis as the other factors such as temperature and carbon dioxide become limiting.he rate of photosynthesis increases linearly with increasing carbon dioxide concentration (from point A to B on the graph). Gradually the rate falls of and at a certain carbon dioxide concentration the rate of photosynthesis stays constant (from point B to C on the graph).

Energy, Plants & Man Best Answer: Carbon dioxide is needed in the dark reaction as a raw material used in the synthesis of glucose. 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.s carbon dioxide concentration increases, the rate of photosynthesis increases.

Chapter 6: Photosynthesis The action of spectrum of photosynthesis in plants roughly corresponds to the absorption spectrum of the pigment chlorophyll, but not exactly. Light with a wavelength of 500 nm (blue-green light) can stimulate photosynthesis even though blue-green light is not absorbed by chlorophyll.

- So by level of light you probably mean light intensity which is something that can be measured. Light intensity is usually defined as the energy hitting an area over some time period. So in the case of a plant, a higher light intensity means more packets of light called “photons” are hitting the leaves.

Why the rate of Photosynthesis is higher in red light while the rate of absorption is highest of blue light? All Answers (8) 1  For the process of photosynthesis, light is abosorbed by Photosystem II which are membrane bound. Photosystem II aborbs infrared and red light (540nm-630nm) and it is for this reason that photosynthesis is highest under red light. 2  Blue light is absorbed not only by chlorophyll, but. also by carotenoids, and some carotenoids are not in the chloroplasts; further, carotenes and xanthophylls make up the carotenoids.. and. Carotenes do not transfer absorbed energy efficiently to chlorophyll, and.

4. Increasing the light intensity will boost the speed of photosynthesis. Carbon dioxide concentration. Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air. Even if there is plenty of light, a plant cannot photosynthesise if there is insufficient carbon dioxide.

Light Absorption for Photosynthesis Light Absorption for Photosynthesis Photosynthesis depends upon the absorption of light by pigments in the leaves of plants. The most important of these is chlorophyll-a, but there are several accessory pigments that also contribute.

Campbell Chapter 10: Mastering Biology Questions One cannot tell from this graph, but because chlorophyll a does absorb red light, we can predict that it would be effective in driving photosynthesis. If only chlorophyll a were involved in the light reactions, would blue light (wavelength about 490 nm) be effective in driving photosynthesis?

Why does increasing the frequency of incident light decrease photoelectric current? NOTE : Increase in intensity means increase in the number of photons or constituent particles. But increase in frequency means increase in the energy possessed by these particles. In the case of visible light, increase in intensity is seen as increase in brightness. Increase in frequency, is seen as a change in color. Note that, when the intensity of the incident radiation is increased, the energy of the photoelectrons emitted does not increase.

Light Intensity and Rate of Photosynthesis (Carol Cao) Light Intensity and the Rate of Photosynthesis. Based on the data collected, the distance the lamp was placed from the test tube with the Elodea plant in it did affect the number of bubbles that formed and floated to the top of the test tube.ince the oxygen bubbles are a product of photosynthesis, one can conclude that the more bubbles formed, the more photosynthesis occurred, thus increasing the rate of photosynthesis. Experimental Design. This experiment will look at the affect of light intensity on the rate of photosynthesis on Elodea plants.

Limiting factors of photosynthesis? The maximum rate of photosynthesis is controlled by the limiting factor. For instance, increasing the temperature from 10ºC to 20ºC could double the rate of photosynthesis as the plant's enzymes will be closer to their optimum working temperature.
