Photosynthesis under artificial light: lighting should provide plants with energy a reduction in plant growth, whereas treatments containing up to . 2 which color was the most detrimental to plant growth what is the wavelength of the light for this color (see fig 1) it is expected that green would be the most detrimental the wavelength is about 550 nm 3 the color of an object is the portion of the visible light that is reflected, while other wavelengths of light are absorbed by the object. Photosensitizers and light have been published (so et al 2010) however, no data on the effect of monochromatic light and photosensitizers on ﬁlamentous fungi have been reported this study also investigated the effect of blue light with and without erythrosine (ery) on the viability of nongerminated and germinating ﬁlamentous conidia.

To plants, red and blue light are the most important--green light is not absorbed and reflects back, giving plants their green coloration--driving germination, growth, circadian rhythms and other life processes function red light induces several behaviors in plants red light controls flowering, according to the oregon state university extension. Results: this experiment was performed in order to verify how short-wave uv light exposure can affect the yeast rate of survival, which was determined by exposing ypd plates to uv light for different periods of timethe yeast culture that was not exposed to uv light at all had an average survival rate of 100% as it is possible to observe on figure 1 (fig1).
Test the effects of ultraviolet (uv) exposure on bacterial growth. Dependent: the other yeast samples that have been affected by various uv rays from different lights procedure screw in each light bulb in different rooms that will remain undisturbed and that will not receive any other light exposure except for the light from the specific light bulb for the time the experiment will be done (24 hours).
