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.
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.
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 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.
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.
What gas do plants give off in the light gizmo answer key?
1 snail and 2 plants
in light the tube turn blue from the plants’ oxygen and at night it becomes stable because the plant turns into like an animal and releases carbon Dioxide and takes in the oxygen from the 12 hrs in the light.
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.
How does light color 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.
How does light color affect oxygen production in photosynthesis?
how does the color of light affect the rate of photosynthesis? The color of light affects the rate of photosynthesis when the production of oxygen increases at 450 nm (blue), drops, then rises again at 660 nm (orange).
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.
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.
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 …
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 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).
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.
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.
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.
What is the rate of photosynthesis?
The rate of photosynthesis is a gross measure of the rate at which a plant captures radiant energy and fixes it in organic carbon compounds.
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.
How does red and blue light affect photosynthesis?
Different wavelengths penetrate differently into the leaf, blue and red are efficiently absorbed close to the surface, whereas green light contributes more to photosynthesis in deeper leaf layers (Sun et al., 1998
Brodersen and Vogelmann, 2010).
Can plants grow in green light?
Green light is the least effective for plants because they are themselves green due to the pigment Chlorophyll. Different color light helps plants achieve different goals as well. Blue light, for example, helps encourage vegetative leaf growth. Red light, when combined with blue, allows plants to flower.
Can plants See green light?
Out of all the light on the visible spectrum, plants reflect green light the most and absorb it the least.
What happens to the O2 and CO2 levels?
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
What gas does plants give off in the light?
The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.
How do the oxygen O2 and carbon dioxide CO2 levels change over time quizlet?
Photosynthesis increases the oxygen levels in the atmosphere. Thus it is then taken up by organisms and changed to Carbon Dioxide. Decomposition increases the amount of CO2 which can be used through photosynthesis to then produce more oxygen for organisms to use in respiration.
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 are leaves green?
So, plants and their leaves look green because the “special pair” of chlorophyll molecules uses the red end of the visible light spectrum to power reactions inside each cell. The unused green light is reflected from the leaf and we see that light.
