Type Of Light Affects The Rate Of Photosynthesis

The amount of light can change the number of the bubble which is the air that the photosynthesis product, it increase the speed to produce the air. when the intensity of light is high, you will get a greater rate of photosynthesis. Light intensity is usually defined as the energy hitting an area over some time period. At low light intensities and when light intensity increases, the rate of the light-dependent reaction, and therefore photosynthesis generally, increases proportionately. The more photons of light that fall on a leaf, the greater the number of chlorophyll molecules that are ionized and the more ATP and NADPH are generated. As light intensity increases, the rate of photosynthesis will increase as long as other factors are inadequate

Explanation to our experiment: To test our hypothesis, we made greenhouses and we grew radishes under it. To make different colors of light affect the growth, we wrapped colored cellophane around the greenhouses so when the sun’s rays strike the greenhouse (passing through because it’s translucent) they will carry the color. The method which we measure the group was by mass and height. However with the problem that measuring the mass of the radish would take pulling out its roots, we only measured on the last day. Our height was measured throughout each of our three days of measuring and the greenhouse with the best radishes (mass and heightwise) would be concluded as the result.

The purpose of this experiment was to determine whether spinach leaves would produce more CO2 if spinach was under blacklight, versus in the the dark. It was hypothesized that if spinach was put under blacklight, then spinach would produce less CO2 because there would be some light energy entering the plant, and that would cause the spinach to photosynthesis. This would decrease the rate of CO2 production. The data did not support this hypothesis. This investigation was valuable because it showed that respiration was still happening in the dark, which can lead to other investigation. This is also important because this showed the effects of different wavelengths of light on the rate of CO2 production in plants, and info into what might be happening

As the rate of both photosynthesis and cellular respiration are being measured under two different conditions, one being different colors of light and the other being temperature. As the measurements will be concentrations over time. The chemical formula that will be implicated will

If a red light is shown on the leaves, then the rate of photosynthesis will decrease. The experiment conducted shows that red light is not efficient for photosynthesis. When the discs were placed in front of the red light, the discs floated on a much slower pace than the discs in the white light. The hypothesis was correct; the discs floated much slower in the red light. This is probably because the red light appears much dimmer than the white light. Since the leaf needs light for photosynthesis, the light that is dimmer will work less efficiently.

As the table lamp is positioned nearest to the pond weed, it shows highest rate since higher light intensity means more photons are striking at the surface of leaves. When the light intensity rose from low to high, it will cause the rate of photosynthesis to increase due to more light energy presents to operate the reactions of photosynthesis. Generally, when the intensity of light is high, a greater rate of photosynthesis will be achieved. However, this rate has a limit, and once that limit is reached the rate cannot be increased to past that limit. It is because the oxygen gas will start to compete for RuBP carboxylase with carbon dioxide at a certain light intensity, whereas the more oxygen gas binds to the enzyme, the less glucose is produced,

As a control for the effect of temperature, one of the samples was kept at room temperature which is 25° C (Tube 3). Since the experiment we conducted on September 23, 2010 during Biology Lab 101 was conducted at room temperature, we had baseline data for what the rate of photosynthesis at this temperature would be. We concluded that this data could be used as a control to compare the rates of photosynthesis in both our experimental tubes. This tube was housed in a water bath set to 25° C. Contents of this tube included 1 mL of DPID, 1 mL of the buffer solution, 3 mL of water, and 3 drops of chloroplasts.

Items for this experiment will include: a large pan, water, diluent, safe gloves, testing strips, a UV light (blacklight), beakers/ test tubes, a pipette, corn samples, as well as a clean lab and clean workstation.

Autotrophs make their own food, by using the energy of the sun to make sugars from carbon dioxide and water. Heterotrophs depend on photosynthesis to consume carbon dioxide and then produce oxygen (respiration). Oxygen and an energy source create ATP, which powers cells. All life ultimately depends on photosynthesis, whether directly or indirectly. . Light is the most important component that affects photosynthesis, because it provides the energy necessary for driving the reaction. Without light, plants cannot create ATP or NADPH, which is how the plant creates sugars to feed itself, therefore causing it to die. In the oxidation and reduction process, sunlight is the energy source that moves electrons from oxygen to carbon.

For the purpose of the experiment , photosynthesis would require water , carbon dioxide and light. As the light produce a certain wavelength, it would show a light color for human eyes to appear. In the experiment we have tested four types of color which would have start the process of photosynthesis. It would mean that if there is light that would create a type of wavelength which would start the process of photosynthesis by starting to take carbon dioxide with water and to produce glucose and oxygen. As a way to test for those types of light we would take the spinach and place it inside a chamber , then we would take the carbon dioxide sensor and place it inside the chamber with a the type of light traveling through the chamber. The carbon

Three hypotheses are formed to conduct and evaluate. The first experiment, changing the color of the lights, hypothesis one states the intensity of the green light will have a greater increase and effectiveness to the plant than the natural or red light. The green light will influence the photosynthesis in the plant because it is more absorbent to the plant. The green light gives the plant a more closer feel to its original environment and the amount of light it would receive in its original environment.

In my experiment I am going to see how light affects the rate of photosynthesis. To do this experiment I am going to set up the apparatus as shown in figure 1.

There are three main factors that can change the rate of photosynthesis. When a plant is going through photosynthesis there are many steps in the reaction where each requires optimal conditions in order to maximize the activity. The factors that can slow the whole process of photosynthesis are called the limiting factors. These factors include light intensity, CO2 concentration, and temperature. In this experiment, the light intensity is being investigated on how this limiting factor can affect the rate of photosynthesis. In the process of photosynthesis, light is used in the light dependent reaction where it is needed for the photoactivation of electrons and the photolysis of water. Low light intensity will result in low production of photons. Therefore, there is less H^+ ions being pumped which results in the slower rate for photosynthesis. From the equation above, O_2 is a product from the process of photosynthesis. When there is a slower rate, there is less oxygen produced, thus the amount of bubbles floating through the
