What is emitted towards an object, the object absorbs

What is the effect of various light sources on the process of photosynthesis? Photosynthesis is a process in which light provides energy to make food. During the process, a plant uses carbon dioxide gas and water to make food and oxygen. ( Interactive Science: The Diversity of Life, 85).  One form of energy is light which can be given off in many ways. When light is emitted towards an object, the object absorbs the light due to photons, small units of electromagnetic energy. The energy of a photon depends on the pigment and frequency of the light source. (World Book Student, Light) In the process of Photosynthesis, green plants use light energy, carbon dioxide, and water to produce glucose, oxygen, and water. Light energy is converted into chemical energy for use in plants. ( 6CO2 + 12H20 + light ? C6H12O6 + 6O2+6H2O) (softschools.com, 2005) Chlorophyll, a green pigment helps plants absorb light. The leaves of a plant have food making cells containing chlorophyll in small bodies called chloroplasts where energy from causes water to split into separate atoms, oxygen and hydrogen. Then, carbon dioxide and hydrogen combine to form a sugar. During the process the oxygens water is given off.  The combination of glucose, sulfur, nitrogen and phosphorus from soil gives green plants the ability to produce complex compounds, starch, fat, protein, vitamins that are needed for the basic structure of life. Thus photosynthesis provides the chemical energy necessary to produce these compounds. (World Book Student, Photosynthesis). Carbon dioxide, light, and even water all can affect Photosynthesis. Increasing one of these variable won’t help if there is not a sufficient amount of the other two variables.  Most places on earth, have the same amount of Photosynthesis.  When a plant opens holes in its leaves, it is taking in carbon dioxide. The holes are too small to see without a microscope, but they let water vapor out of the plant. The holes on the plant are so tiny that you can not see them without a microscope.  Yet they are tiny they have a important job of letting water vapor out of the plant.  Thus, water is important in the process of photosynthesis. More light causes problems if water is scarce. One can see that increasing light can cause water being limited. The intensity of light can be measured. Higher light intensity means more photons, packets of light, are hitting the plant. As you increase light intensity the rate of photosynthesis increases. However, as the light intensity increases the rate of photosynthesis is limited due to other factors such as the amount of chlorophyll. If light, carbon dioxide, or  water are in short supply photosynthesis will not proceed.  If you have too much light, carbon dioxide and water become limited and photosynthesis is obstructed. The result can be sunburn damage as seen with a leaf with large brown dry sections. If there is too little light, Photosynthesis is interrupted due to plants not producing enough sugar. (http://scienceline.ucsb.edu/getkey.php?key=4647). Photosynthesis is essential in supporting life on earth. Without photosynthesis, there would be little food or organic matter and the Earth’s atmosphere would lack oxygen. Photosynthesis has made it possible to produce energy creating fossil fuels such as coal, oil, and gas to promote the industrial society. These fuels provide much of the energy used in factories, homes, and transportation. They also serve as the raw material for plastics and other synthetic products. (Encyclopedia Britannica, Photosynthesis)What is light? Light is a type of traveling electromagnetic energy. The energy travels in patterns of electric and magnetic influence called electromagnetic waves.  Types of electromagnetic waves include Infrared rays, radio waves, ultraviolet rays, and X rays. Electrons, which are small particles with tiny negative electric charge produce light.  The term excited refers to an atom with this kind of electron. It can transfer the energy to another atom or its electrons can emit, give off, visible light. Light carries away extra energy. Electrons emit electromagnetic waves, with a certain frequency which is the number of individual waves or cycles that pass a given point in a certain time (World Book Student, Light).There are many types of light sources which could be considered in the process of photosynthesis.  Natural light is the energy given off by the sun, and artificial light in most cases in electric light. A light bulb is a container made of glass having materials in it that produce light with an electric current.  A few different kinds are incandescent, CFL, LED, halogen, and black lights. The first bulbs otherwise called lamps invented were incandescent, which use thin metal wires named filaments. As electric current runs through it the filament glows. CFL’s or compact fluorescent lights are glass tubes filled with gas.  As electricity passes through the tube the glass coating glows (World Book Student, Light Bulbs).  LEDs or light-emitting diodes are used in some bulbs. They can even be used in electronic devices, traffic lights, street lamps, car headlights, and even on remote controls. LED lights use electric power more efficiently. (World Book Student, Light-Emitting Diode). A halogen light is a type of incandescent light with a tungsten filament sealed into a small transparent envelope filled with inert gas and halogen. Halogens produce higher luminous efficacy and color temperature. Halogen lamps are used in projectors. (Wikipedia, Halogen lamp). A black light is an invisible ultraviolet light. (Merriam Webster, Black light).Works CitedSpilman Vogt, Vogt, Alexis K., and Thomas G. Brown. “Light.” World Book Student, World Book, 2017, www.worldbookonline.com/student/article?id=ar323260.
