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.
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.
What is the limiting factor in photosynthesis gizmo?
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.
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.
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 oxygen production relate to the rate of photosynthesis gizmo?
How does oxygen production relate to the rate of photosynthesis? Oxygen production relates to the rate of photosynthesis because when the oxygen production is high the rate of photosynthesis is high.
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 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 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.
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.
What colors are absorbed best 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 the color of light affect the rate of photosynthesis quizlet?
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).
How does the color of the 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.
How does light intensity affect oxygen production gizmo?
up to 40% increasing the light intensity increases the oxygen production. Beyond 40% there is no effect. if the temp were extremely hot or cold, then oxygen production would be near zero no matter what light intensity value you use.
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 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.
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 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.
What color light do plants absorbs worst?
Regardless of whether the color of the light is red or purple the plant will absorb some amount of energy from the light it is receiving. Green light is the least effective for plants because they are themselves green due to the pigment Chlorophyll.
How does oxygen affect the rate of photosynthesis?
Oxygen inhibits the photosynthesis of C3 plants at atmospheric CO2 concentration (Varburg effect). The main cause of this phenomenon is the competitive inhibition of RuBP carboxylation and stimulation of RuBP oxygenation, the latter resulting in formation of glycolate and photorespiratory CO2.
How does light color affect oxygen production hypothesis?
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 …
How does temperature affect light intensity?
The greatest light intensity for each mineral sample, was when it was at an extreme temperature, whether it be hot or cold. Extreme temperatures initiate the greatest change in the light intensity of a fluorescent rock.
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.
What is the ideal CO2 level for photosynthesis?
For most crops the saturation point will be reached at about 1,000–1,300 ppm under ideal circumstances. A lower level (800–1,000 ppm) is recommended for raising seedlings (tomatoes, cucumbers and peppers) as well as for lettuce production.
How do you determine the rate of photosynthesis?
By actually measuring the volume of oxygen gas produced by a plant, you can work out the rate at which photosynthesis is happening. The more oxygen given off, the higher (or faster) the rate of photosynthesis.
What factors speed up or slow down the rate of photosynthesis?
Answer and Explanation: The environmental factors that speed up or slow down the rate of photosynthesis are temperature and the availability of sunlight and carbon dioxide. …
What are three factors that affect the rate of photosynthesis?
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
Does light affect photosynthesis?
As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.
What are the 4 factors that affect photosynthesis?
Several factors can affect the rate of photosynthesis: light intensity. carbon dioxide concentration. temperature….These include:
- the rate of oxygen output.
- the rate of carbon dioxide uptake.
- the rate of carbohydrate (glucose) production.
How does water affect the rate of photosynthesis?
Solution : Water controls the opening and closing of stomata. The deficiency of water causes stomata to open very little or it may even remain closed. Therefore, `CO_(2)` (required as a raw material for photosynthesis) cannot enter into the leaves and thus lack of water slows down the rate of photosynthesis.
