Will plant's give act differently to artificial light?

Question

Will Phototropism still be possible for the plant when using artificial light? I need this for my I.P. in Biology class. You'd be a big help. Thanks in advance. :)

Answer 1

Yes...  Lack of adequate light is the most common factor limiting the growth of plants in many areas of the home. Supplementary electric lighting is usually the easiest way to provide enough light for plants that do not receive adequate natural light.  Plants growing outdoors, in greenhouses or close to windows are exposed to a natural balance of the blue and red light rays that plants need. Where plants receive little or no natural light, you must provide additional light from artificial sources. Most people are familiar with the incandescent light produced by ordinary light bulbs in our homes. As a single light source for plants, these bulbs are not particularly good. They are a good source of red rays but a poor source of blue. They produce too much heat for most plants and, if used, must be kept away from the plants, thus reducing the intensity of the light the plants receive. They are also about three times less efficient than fluorescent tubes in converting electrical energy to light. Furthermore, a standard incandescent bulb's life is often only about 1,000 hours, whereas a fluorescent tube's life is normally 10,000 hours or more. Fluorescent tubes provide the best artificial light sources available for plants in the home. Other light sources such as sodium lamps may be used but are not normally available or adaptable for home use.
