Research paper on light bulbs

Abstract Electricity is a world wide know source of made light. Electricity is a form of energy that is produced by the movement of electrons. Another way of receiving electricity would be solar electricity.

Our hypothesis is if we use a fluorescent light bulb then the plant growth would be higher in quality height and healthiness because it supplies better supplemental light and the plant has a better chance of survival compared to the incandescent light bulb.

The plant that is grown underneath a fluorescent light bulb has a more chance of survival because incandescent light bulbs are too hot and can burn the plant if to close. For this experiment you would need two lamps small desk lamps and one fluorescent light bulb and one incandescent light bulb.

Also you would need three plants one to go under the fluorescent light bulb and one to go under the incandescent light Research paper on light bulbs and one to put in the sun to see how the plant would normally grow. The necessary thing that you need for every plant is water which provides oxygen.

To set this experiment up all you need is clean area such as a table. Each plant started at the height of 3cm and we grew then for 3 weeks. The plant that grew the most out of the three plants was the plant in the sun which grew 10 cm.

The plants under the fluorescent light bulbs grew 1cm from the 1st week and grew 1. Overall the fluorescent plant grew 5. On the second week the plant underneath the incandescent light bulb grew as much as the fluorescent light bulb grew on the last week which was 5. On the last week of the experiment it was 7cm in height.

Our hypothesis was correct in the fact that it was healthier then the plant under the incandescent light bulb, the soil of the plant under the incandescent light was dry and the plant looked as if it were about to die, on the other hand the plant growing under the fluorescent light had moist soil and it was full of life and just generally better looking.

Plants take sunlight and turn it into energy for them to use this energy is used to help the development of the plant and its growth. How are they going to grow their crops without the main source of energy to the plant? Most people in Alaska grow there plant indoors using an alternate light source.

Brining us to your experiment on which type of light bulb will help a plant grow the same way it would if it had sunlight. Every plant needs certain materials to keep it alive such as oxygen, water, sunlight etc.

Sunlight is one of the main sources of energy that help plants grow. Plants take the sunlight that they receive and turn it into chemical energy which is stored and used later. Light is needed to make plant leaves green, without light the leaves stay pale or white.

Plants with white leaves cannot make their own food but when u put a plant in light, the leaves will turn green. This process starts with the sunlight combining with chlorophyll in the leaves and light energy turning it into chemical energy.

Photosynthesis is also sole source of organic carbon that all carbon based life forms use to build stuff of their existence. Harvesting sunlight and storing the energy is the only thing that photosynthesis can do in chemical bonds of sugar. Light energy cannot be used directly from the synthesis of macromolecules.

Since light energy cannot be used directly from the synthesis this is where cellular respiration comes in. Cellular respiration is when it takes energy from sugar and changes it into a molecule that is immediately available to work in the cell.

The way a plant is designed it appears to be made to facilitate the harvesting of sunlight. When planting plants indoors you still need the sunlight to help with the plant growth. For indoor plants they use lights light bulbs as there sunlight. Certain light bulbs give the same type light from the electromagnetic spectrum as the sun would give off towards plants.

Although visible light is a very small part of the electromagnetic spectrum, it is responsible for a lot of biological reactions like photosynthesis and life has become very dependent on this small portion. Light quality refers to the color wavelength of light. Sunlight supplies the complete range of wavelengths and can be broken up by a prism into bands of red, orange, yellow, green, blue, indigo, and violet.

Knowing which light source to use is important for manipulating plant growth. For example, fluorescent cool white light is high in the blue wavelength. It encourages leafy growth and is great for starting seedlings. Incandescent light is high in the red or orange range, but generally produces too much heat to be a valuable light source for plants.

Fluorescent grow-lights attempt to imitate sunlight with a mixture of red and blue wavelengths, but they are more expensive and not really better than regular fluorescent lights.
