Does wavelength affect the rate of photosynthesis

The exact opposite actually it true, blue lightwith the short wavelength colors such as blueactually penetrating the deepest, while longwavelength colors such red light penetrates theshallowest. Not to mention that in coastal watersgreen light is actually the spectrum thatpenetrates deepest....

How does light intensity and duration affect the rate of photosynthesis?

This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised best at around 20 degrees centigrade.) Light, temperature & CO2 are known as limiting factors, and each is as important as the next in photosynthes...

The Affect of Wavelengths of Light on Rate of Photosynthesis

Solar radiation is described in terms of its energy content and its wavelength....

Light Filters are used and
light intensity stays the same The colors used in order of wavelength
blue being the smallest and red the largest so the order will go
white, blue, green, yellow, orange, red.


Independent Variables

1) Fill the conical flask with 250 ml of 0.2 M sodium bicarbonate solution.
2) Set up the experiment by carefully plugging the lamp into a power socket, however make sure the power switch of the lamp is on mode ‘off’.
3) On a computer, open the data logging software.

Investigating the Effect of Light Wavelength on the …

Explore the frequency, wavelength, amplitude and velocity of sound waves.

Some of these variables are listed below: · Light Wavelength · Carbon Dioxide (sodium hydrogen carbonated) · Temperature · Water All these factors will have to be kept constant except the...

Certain pigments are better at absorbing certain wavelengths of light, and for chlorophyll, blue and red lights are more easily absorbed while green is reflected off it.

Both of these have an affect on photosynthesis.

Since the particles' sizes are of much biggerwavelength than EM, the red wavelengths will bemore scattered than the blue, so that also will notfavor transmission of the redish photons.

that the wavelength of the light also ..

Considering that not all light energy is used for photosynthesis we propose an alternative hypothesis. In a previous experiment the pigment xanthophylls absorbed significant amounts of blue light. In new research it is found that this pigment could be an important component in a process called energy dissipation rather than photosynthesis. In order to not overwhelm the plant with photosynthesis and respiration, this photon energy goes to other functions or formations of the plant. Further research on the function of xanthophylls will need to be conducted in order to understand the processes of plant function.

I will do this by placing the Elodea in a test tube with sodium hydrogen carbonate then I will vary the light wavelength (color) using colored filters and count the number of oxygen bubbles given off using a pencil dot technique....

Hypothesis Wavelength Of Light And Photosynthesis

"It seems strange that plants would harvest thelower energy red light instead of the higherenergy green light, unless you consider that, likeall life, plants first evolved in the ocean. Seawater quickly absorbs the high-energy blue andgreen light, so that only the lower energy, longerwavelength red light can penetrate into theocean."
