The limiting factor was CO2 because when it was decreased or increased, it was still able to increase the oxygen production. I know that CO2 is the limiting factor because it always increases oxygen production.. Challenge: In each of the situations below, use the Gizmo to find the limiting factor.
What are the ideal conditions for photosynthesis gizmo?
Introduction: Photosynthesis requires light, water, and CO2 to work. When one of these factors is in short supply, it is called a limiting factor. Temperature can also be a limiting factor when it is too hot or too cold for photosynthesis to work well.
Which color of light do you think will maximize the rate of photosynthesis gizmo?
Which color of light do you think will maximize the rate of photosynthesis? I think that the color blue will maximize the rate of photosynthesis because I found it to be most effective at increasing the production of oxygen.
How does temperature affect oxygen production in photosynthesis gizmo?
How does temperature affect oxygen production? Oxygen production is maximized at 25C. Oxygen production goes down when temperature is too hot or too cold.
How does the photosynthesis gizmo lab determine the rate of photosynthesis?
In the Photosynthesis Lab Gizmo, you can monitor the rate of photosynthesis by measuring oxygen production.
Which of the following can be used to measure the rate of photosynthesis gizmo answers?
Oxygen production is used to measure the rate of photosynthesis. Light intensity, carbon dioxide levels, temperature, and wavelength of light can all be varied. Determine which conditions are ideal for photosynthesis, and understand how limiting factors affect oxygen production.
Which color of light will maximize the rate of photosynthesis?
The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.
What color light is best for photosynthesis?
The majority of green light is useful in photosynthesis. The relative quantum efficiency curve (Photo 1) shows how efficiently plants use wavelengths between 300 and 800 nm. Green light is the least efficiently used color of light in the visible spectrum.
How does color of light affect the rate of photosynthesis?
The wavelength of a color is directly related to the rate of photosynthesis, with longer wavelengths leading to higher rates of photosynthesis. Photosynthesis takes place primarily in the leaves of plants.
Why does green light slow down photosynthesis?
The hypothesis was that the lights higher on the light spectrum, like blue, would have the fastest rate of photosynthesis because the energy is the highest
the green light would have the slowest rate because the chlorophyll inside of the leaves reflects green light, so it will not be absorbed as much as the other …
Why does green light affect photosynthesis?
Because green light can penetrate further into the leaf than red or blue light, in strong white light, any additional green light absorbed by the lower chloroplasts would increase leaf photosynthesis to a greater extent than would additional red or blue light.
What colors are best absorbed by plants?
Short answer: plant absorbs mostly “blue” and “red” light. They rarely absorb green for its mostly reflected by plant, that makes them green! Long answer : Photosynthesis is the ability of plants to absorb the energy of light, and convert it into energy for the plant.
How does light color affect oxygen production?
The higher the intensity of light, the more will be the production of oxygen in the form of bubbles by the plants under the process of photosynthesis. Therefore, when you reduce the distance between the light and the plant, there are more oxygen bubbles produced by the plants.
What temperature will result in the highest rate of photosynthesis?
At medium temperatures, between 50 and 68 degrees Fahrenheit, or 10 and 20 degrees Celsius, the photosynthetic enzymes work at their optimum levels, so photosynthesis rates gauge high. Depending on the particular plant in question, set the greenhouse thermostat to a temperature within this range for best results.
How does temperature affect photosynthesis?
The rate of photosynthesis is influenced by temperature. Higher the temperature, greater the rate of photosynthesis. This is because photosynthesis is a chemical reaction and most of the chemical reactions are accelerated with temperature.
How will you determine the rate of photosynthesis quizlet?
How can photosynthesis be measured? Directly: by the production of oxygen(counting bubbles) or the uptake of carbon dioxide (measuring pH of surroundings).
What is the purpose of the photosynthesis lab?
To test the ability of plants to synthesis their food (sugars). To demonstrate the effect of light, carbon dioxide and chlorophyll on photosynthesis.
Which color of light would you expect to produce the lowest rate of photosynthesis?
The lights higher on the light spectrum, like blue, would have the fastest rate of photosynthesis because the energy is the highest. The green light would have the slowest rate because the chlorophyll inside of the leaves reflects green light, so it would not be absorbed as much as the other colors.
Why is chlorophyll green?
The process of photosynthesis produces oxygen, which is released by the plant into the air. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.
Which of the following can be used to measure the rate of photosynthesis ?\?
The incoming and outgoing CO2 from the leaf chamber is measured by infrared spectroscopy with an infrared gas analyzer. The difference gives us the amount of CO2, from which the rate of photosynthesis can be calculated.
Can temperature be used to measure the rate of photosynthesis?
Temperature. As with other chemical reactions, the rate of photosynthesis increases as the temperature rises. Photosynthesis is controlled by enzymes , which become denatured if the temperature is too high. As a result, the rate of photosynthesis reaches its maximum at an optimum temperature, then decreases.
Is red or blue light better for photosynthesis?
It was concluded that blue light is more essential than red light for normal photosynthesis by mediating photosystems activity and photosynthetic electron transport capacity.
Why is blue the best color for photosynthesis?
Blue photons drive the photosynthetic reaction, although from an energy standpoint, one might consider them less efficient than green or red photons because their high energy isn’t fully utilized
some of the energy is essentially lost compared to photosynthetic photons with a longer (less energetic) wavelength.
Why is blue light good for photosynthesis?
Blue light plays an important role in most plant functions. Blue light is highly absorbed by both chlorophyll a and b, as well as an intact leaf system. This high absorption rate corresponds to the photosynthetic action spectrum from isolated chloroplasts and intact leaves.
Why does light affect photosynthesis?
At a very high intensity of light, the rate of photosynthesis would drop quickly as the light starts to damage the plant. This is a very important aspect of photosynthesis. As you are probably aware, Photosynthesis is a chemical reaction that captures light energy and turns it into sugar.
What colors of light do plants not absorb?
Chlorophylls do not absorb wavelengths of green and yellow, which is indicated by a very low degree of light absorption from about 500 to 600 nm. The absorption spectrum of β-carotene (a carotenoid pigment) includes violet and blue-green light, as is indicated by its peaks at around 450 and 475 nm.
Why is red light more effective in photosynthesis?
Red light is more effective in photosynthesis because both the photosystems (PS I and PS II) absorb light of wavelengths in the red region (680 and 700 nm, respectively). Furthermore, blue light is absorbed by carotenoids, which pass the energy to the chlorophyll. Light in the red region is absorbed by chlorophyll.
Which light photosynthesis takes place faster?
In order to absorb the blue color of light in the greatest quantity, the maximum intensity of photosynthesis occurs in red light. So, the correct answer is, ‘Red light’. Note: Chlorophyll is a green-colored pigment that in plants absorbs light for photosynthesis.
How does light affect photosynthesis lab?
An increase in light intensity will produce an increase in the rate of photosynthesis until a level of light intensity is reached [normally 38% 1] above which the rate does not increase because the light saturation point has been reached and another factor (CO2 concentration or temperature) is limiting.
How do different colors of light affect plant growth experiment?
The plant under the green light actually grew the slowest. The plant that grew the fastest was the plant under the red light. The results of this experiment show a slight preference for growth for the red light followed by white or blue and then green light.
