How does the color of light affect plant growth experiment results?
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.
What colors of visible light will increase the rate of photosynthesis?
Clear light increased the rate of photosynthesis the most, as was expected. Out of the colored lights, blue had the shortest wavelength and the fastest rate of photosynthesis.
How did light affect the rate of photosynthesis?
As light intensity increases, the rate of photosynthesis will increase as long as other factors are in adequate supply. As the rate increases, eventually another factor will come into short supply. The graph below shows the effect of low carbon dioxide concentration.
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).
Why does red light increase the rate of photosynthesis?
For the process of photosynthesis, light is abosorbed by Photosystem II which are membrane bound. Photosystem II aborbs infrared and red light (540nm-630nm) and it is for this reason that photosynthesis is highest under red light.
Why is red and blue light best for photosynthesis?
The wavelength of blue light is 475 nanometers while the wavelength of red is 650 nanometers. BLUE light carries a higher energy signature then RED light does and that higher energy with a shorter wavelength should provide the plants with a better environment for growth.
Which colors of light are most effective for photosynthesis explain why?
Certain red and blue wavelengths of light are the most effective in photosynthesis because they have exactly the right amount of energy to energize, or excite, chlorophyll electrons and boost them out of their orbits to a higher energy level.
Why does blue light increase the rate of photosynthesis?
BLUE LIGHT AND PLANT GROWTH In addition, blue light regulates the opening of stomata, which are the tiny openings on leaves that control both water loss and the uptake of carbon dioxide. Generally, only a low intensity of blue is needed in a light spectrum for fully functional photosynthesis.
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.
Why do you think the photosynthesis was greater with this color than with the others?
Blue and red filters will give plants the light spectrum that they use for photosynthesis, therefore they will yield the greatest rate of photosynthesis. Chlorophyll and carotenoid pigments are optimized for absorption of blue and red light.
Why does color affect 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 photosynthesis is more in red light?
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.
Why is blue the best color for 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 color light causes 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 red and blue light affect photosynthesis?
Biomass and photosynthetic parameters increased with an increasing light intensity under blue LED illumination and decreased when illuminated with red and green LEDs with decreased light intensity.
Why does photosynthesis occur most slowly under green light?
Answer 2: Chlorophyll absorbs red light. No light gets absorbed by chlorophyll means the plant can't do photosynthesis.
Which colors of light are most effective for photosynthesis and why?
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.
Why does blue light speed up photosynthesis?
BLUE LIGHT AND PLANT GROWTH In addition, blue light regulates the opening of stomata, which are the tiny openings on leaves that control both water loss and the uptake of carbon dioxide. Generally, only a low intensity of blue is needed in a light spectrum for fully functional photosynthesis.
How does yellow light affect photosynthesis?
Plants absorb some yellow and orange light, but these wavelengths are not the most important for photosynthesis. Seedlings given yellow or orange light alone will not be able to create carbohydrates, and so will not grow and thrive.
Why is red the best color for photosynthesis?
No light gets absorbed by chlorophyll means the plant can't do photosynthesis. Answer 3: Trees and plants are green because of a green pigment called chlorophyll. This pigment absorbs red light the best, and converts the light into energy that it uses for metabolism.
How does color affect photosynthesis?
Plants do respond differently to different colors of light being shone on them, because chlorophyll reflects green light and absorbs blue and red (therefore, blue and red are useful for photosynthesis, but green isn't).
How does red light affect photosynthesis?
Red Light (620nm-700nm) Red light helps to flower and fruit and prolong flowering. It can greatly enhance the photosynthesis of plants and promote the growth of plants. but if plants are grown under only red light. They will have a stretched and elongated appearance.
How do you do photosynthesis experiment?
Use a measuring spoon to scoop out 1/8 teaspoon of baking soda, and fill your measuring cup with 300 milliliters of water. Mix the baking soda into the water to create your bicarbonate solution. When the baking soda dissolves in the water, it releases carbon dioxide. This will be used by the spinach for photosynthesis.
How does green light affect the rate of 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 is the conclusion of photosynthesis experiment?
They concluded that light is essential for photosynthesis, and plants use carbon dioxide and water for the preparation of glucose (carbohydrate), where water molecules are the hydrogen donors and oxygen (O2) is the by-product of this biological process.
What is the aim of photosynthesis experiment?
Photosynthesis The aim of this experiment is to investigate the factors affecting photosynthesis in Elodea. Plants photosynthesise in order to produce energy, in the form of glucose, from sunlight.
Why photosynthesis is less in green light?
If the plants are exposed to green wavelengths during photosynthesis, the rate of photosynthesis will be the slowest. This is due to the presence of chlorophyll, a green pigment. Instead of being absorbed by the chlorophyll, the green light is transmitted and reflected.
How does photosynthesis work experiment?
Use a measuring spoon to scoop out 1/8 teaspoon of baking soda, and fill your measuring cup with 300 milliliters of water. Mix the baking soda into the water to create your bicarbonate solution. When the baking soda dissolves in the water, it releases carbon dioxide. This will be used by the spinach for photosynthesis.
What is your hypothesis for this experiment the rate of photosynthesis?
What is you hypothesis for this experiment? The rate of photosynthesis is greater in white light than in darkness. How will you determine the effect of presence of light on the rate of photosynthesis? I will compare the rate of photosynthesis with and without light.
