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 are the bubbles in photosynthesis gizmo?
The gas is produced from plants in photosynthesis. Observe the left pane closely. What do you think the bubbles are? In my opinion, the bubbles are the oxygen that the plant is giving off.
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.
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.
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 color of light affect the rate of photosynthesis gizmos?
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).
Do different colors of light affect the rate of photosynthesis experiment?
Visible light has a wavelength that ranges from 400-700 nanometres. The percentage of light absorbed by plants in photosynthesis differs for the colour of the light. Red and violet light are on opposite ends on the visible light spectrum.Effect of Light Colour on the Rate of Photosynthesis.
| Light Colour | Average Bubbles per minute ± 1 |
|---|---|
| Green Light | 16 |
| Violet Light | 25 |
How does light intensity affect the rate of photosynthesis experiment?
More oxygen bubbles are produced when the light is closer to the beaker. So a greater light intensity gives a greater rate of photosynthesis.
What color of 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 colors are absorbed best by the plant?
As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green.
What temperature is best for photosynthesis?
The optimum temperature range for photosynthesis is 35–40ºC.
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.
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).
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.
How does wavelength affect oxygen production?
Since blue and red wavelengths of light stimulate chlorophyll the best, the green-wrapped test tube should have produced the most oxygen. The blue and red plastic wrap however, blocked blue and red wavelengths of light
therefore less oxygen was produced.
Why does photosynthesis occur most slowly under green light?
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.
How does the light intensity 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.
How does c02 affect oxygen production?
A pure carbon dioxide environment makes the Elodea produce more oxygen than Elodea grown in a normal atmosphere environment. All materials a plant needs to undergo photosynthesis and produce oxygen are carbon dioxide, sunlight, and water.
How do colored lights affect plant growth?
A common question is: Does the color of light affect plant growth? The color of light DOES affect plant growth, but the effect is more noticeable under low light intensity. Red &
blue light are most effective for plant growth, while yellow &
green have minimal effect. UV light can damage plants, causing leaves to burn.
Why would it be hard to find the ideal light intensity if the temperature were very hot or very cold?
if the temp were extremely hot or cold, then oxygen production would be near zero no matter what light intensity value you use. if the light intensity were very low, then the oxygen production would be near zero no matter what C02 level you use.
Why is red and blue light best for 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).
Why is blue light best 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.
Does red light increase photosynthesis?
red light is highly effective at regulating growth and development for plants . Red light helps to flower and fruit and prolong flowering.It can greatly enhance the photosynthesis of plants and promote the growth of plants.
Why does the color of light matter in photosynthesis?
The color or wavelength of light does affect photosynthesis, which is how plants can basically create their own food. Essentially, the reason why plants are green is they are absorbing the other wavelengths of light but reflecting back the green.
Why does photosynthesis occur faster with more light?
So in the case of a plant, a higher light intensity means more packets of light called “photons” are hitting the leaves. 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.
How does distance of light affect photosynthesis?
The further the light moves from the plant, the fewer oxygen bubbles are produced by photosynthesis. The intensity of light at different distances from a light source can be described by the inverse square law.
