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.

Lipoma (Skin Lumps) A lipoma is a growth of fatty tissue that slowly develops under your skin. People of any age can develop a lipoma, but children rarely develop them. They’re classified as benign growths, or tumors, of fatty tissue. This means a lipoma isn’t cancerous and is rarely harmful.

The Duckweed Experiment: Effects of Lowering Light Intensity on the Rate of Per Capita Growth of Lemna Minor Abstract. Duckweed is a small aquatic plant that is able to grow rapidly, making it the ideal specimen for our experiment. It is hypothesized that altering the amount of light received by duckweed will alter its photosynthetic rate. It is predicted that a lower light intensity will lower the rate of growth in duckweed.Two treatment groups were covered with a screen in order to reduce light intensity. Both groups were kept under a controlled light source for fourteen days and plant counts were taken at regular intervals.t is hypothesized that altering the amount of light received by duckweed will alter its photosynthetic rate. It is predicted that a lower light intensity will lower the rate of growth in duckweed. Two treatment groups were covered with a screen in order to reduce light intensity.

- The Doppler effect. We have seen that light always travels at the same speed of about 300,000 km/s; in particular light emitted by a sources in relative motion to an observer travels at this speed.Yet there is one effect on light which shows that its source is moving with respect to the observer: its color changes.he Doppler effect.

What is the effect of temperature on photosynthesis? Thus the overall effect of temperature on photosynthesis is that it increases with temperature to an optimum somewhere between 20C and 30C (for land plants) and then decreases due to decreasing Rubisco efficiency as the temperature increases above that.

- 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.nswer 5: Click Here to return to the search form. I am not sure what you mean by level of light, but I will answer your question in to ways-in terms of the intensity of light and wavelength of light. Photosynthesis needs water, carbon dioxide, chlorophyll, light, and the right temperature.

In the photoelectric effect, why is the kinetic energy of the electrons independent of the intensity of light? If you change the intensity of the incident beam keeping the frequency of light same, you only change the number of photons. The change in that number can't affect the kinetic energy of the emitted electrons. The emission of electrons occurs due to a one electron one photon collision. If one photon of insufficient energy collides with an electron and then another one does, the energy of the electron doesn't become twice that of the incident photon.

Color & Light Effects on Photosynthesis Bright Light Affects Photosynthesis. Bright light is a basic element of photosynthesis, but variations in the color of light have an effect on plants. The entire spectrum of light hits the plant's leaves at the same time, but there are some colors that are known to cause higher amounts of photosynthesis than others.

How does a greenhouse speed up the rate of photosynthesis? Best Answer: The rate of photosynthesis does not necessarily increase, except for the effect of increased temperature. A greenhouse allows sunlight through, but does not allow the infrared that is reflected to escape, so the temperature inside rises and can let plants have a longer growing season.

Carbon dioxide Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration, or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis.Temperature, carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Plants also need mineral ions, including nitrate and magnesium, for healthy growth.xygen is produced as a by-product. This process is called photosynthesis.

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.

Does Light Intensity increase the Rate of Photosynthesis? Set up the two plants in water solution (each plant has a light source with different voltage: 1Watts per gallon and 3Watts per gallon, make sure you use the variable power supply) Set the timer to 1 min. Count the bubbles that forms in 1 min Record results Hypothesis If the intensity of light is greater, then the rate of photosynthesis increases. Graph Results were Things to remember! When there is no light, photosynthesis can't occur since light is the activation energy needed for plants to convert carbon dioxide and water to glucose and oxygen

When you increase light intensity, does the wavelength increase or decrease? When you increase light intensity, does the wavelength increase or decrease? For example, I have a lamp with 4V and 8V option, when it is at 4V, it is dimmer than at 8V. My question is whether or not it has anything to do with an increase or decrease in wavelength.

- A demon addicted to the reprehensible habit of devouring the dead. Worse than all was the reprehensible conduct of Sir Theophilus Parker. Does your law, then, not consider him reprehensible in that desire? Reprehensible as it was he did not want anything to disturb it. He has adopted a tone and manners which I can hardly but describe as reprehensible. He had become satisfied that Alfred was connected with the reprehensible act. If she cared nothing for him, she was acting in a reprehensible manner. Had I known, my conduct in coming to you as I did would have been reprehensible. In the old drama there had been much that was reprehensible. What does he hold to be most reprehensible in this class of work?

How does temperature affect photosynthesis? As the temperature increases, the enzymes get more energy so the rate of photosynthesis increases. If it gets too hot the enzymes begin to lose their shape (denature). This means they are unable to function properly and the rate of photosynthesis decreases again.

Factors affecting the rate of photosynthesis By understanding the factors that affect the rate of photosynthesis they can do work to try and increase the rate of photosynthesis to increase the yield of a crop. The three main things affecting the rate of photosynthesis are: Light. Temperature. Carbon dioxide.

Photosynthesis The action spectrum of photosynthesis is a graph showing the rate of photosynthesis for each wavelength of light. The rate of photosynthesis will not be the same for every wavelength of light. The rate of photosynthesis is the least with green-yellow light (525 nm-625 nm). Red-orange light (625nm-700nm) shows a good rate of photosynthesis however the best rate of photosynthesis is seen with violet-blue light (400nm-525nm).

- RESULTS. The original purpose of this experiment was to determine the effects of different amounts of phosphorous on the photosynthesis of aquatic plants. The results of the experiment were that as the amount of phosphates in the water increased the amount of oxygen given off of the elodea decreased.So the effects were that as the phosphates increased it caused the rapid amount of growth in the algae and caused less amounts of light to reach the plant.ESULTS.

Light Intensity and Number of Photons help? This means that for the same amount of photons emitted, blue light would have a higher energy than red light (because E=hf --> energy is proportional to frequency). Therefore, to obtain the same amount of intensity of blue and red light, there must be less photons of blue light than red light emitted.
