Rate of Photosynthesis Experiment

Photosynthesis and cell respiration are some of the two most important biological processes that organisms go through. Photosynthesis is the biological process plants undergo to convert light energy into chemical energy. In chloroplasts the chlorophyll act as catalysts for this process. The process uses carbon dioxide (CO2) and Water (H2O) in order to produce glucose (C6H1206) and oxygen (02). Thus, it is read as 6CO2 + 6H2O —> C6H12O6 + 6O2. Photosynthesis is split into two different processes. The first process is light Dependent meaning i uses energy being absorbed to break down and molecules at a rapid photosynthetic rate. The second process is Light Independent meaning it uses ATP and NADH absorbed during when light was present to breakdown glucose instead. Therefore, Healthy plants are green because Chlorophyll absorbs red and blue light, but reflects green light signifying stored light.Some Anaerobic bacteria undergo photosynthesis meaning it can’t grow in oxygen and uses Carbon Dioxide and other substances like hydrogen sulfide to photosynthesis. In general all plants need Carbon Dioxide. (Ensminger, 2014)

Photosynthesis occurs each time the sun’s light reaches the lives of a plant. The chemical ingrediants for photosynthesis are carbon dioxide (CO2), a gas that passes from the air into a plant via tiny pores, and water (H20), which absorbed from the soil by the plant’s roots. Inside leaf cells, tiny structures called chloroplasts use light energy to rearrange the atoms of the ingrediants to produce sugars, most importantly glucose (C6H12O6) and other organic molecules. Chlorophyll gives the plant its green color (Simon, 02/2012, pp. 92-93). Chemical reactions transfers the sun’s light energy into the chemical bonds that hold energy-carrying molecules. The most common are

Photosynthesis is the conversion of light energy to chemical energy into sugars. It is the process in plants that uses carbon dioxide, water, and sunlight from its surroundings and releases oxygen as a byproduct (6H2O+6CO2+light energy -> C6H12O6+6O2). Photosynthesis is required for plants because they are autotrophs, organisms that make their own food. Plants require a specific environment that is ideal to them to be able to carry out the process. Environmental conditions can either increase or decrease the rate of photosynthesis. Things like colors of light, pH, and temperature can all affect the rate of photosynthesis in plants.

Photosynthesis is the process in which plants consumed inorganic materials like solar light, carbon dioxide and water and converted it to an organic molecule like sugar and an inorganic gas like oxygen. Light is one of the major elements influencing the rate of photosynthesis; direct light concentration affects the noncyclic pathway (light

Light intensity does affect the rate of photosynthesis. Too much light may cause plants to "burn out" or stop producing oxygen while too little light will not provide enough light for optimal photosynthesis activity and CO2 would stop be taken in and oxygen would stop being produced.

An important part of photosynthesis is the intake of carbon; thus, it can be presumed that increasing the amount of available carbon will increase photosynthetic activity. In most plants there is an increased rate of photosynthetic rate, but it is limited by other factors and reaches a plateau (Lei H, Zhishan Z.

“Photosynthesis is a biochemical process for building carbohydrates using energy from sunlight and carbon dioxide taken from the air”, (Morris, J. (2016) Biology How Life Works. New York, NY.). It is a system that uses plants and specific algae to synthesize molecules from both water and carbon dioxide. The oxygen we breathe and the food we eat is fueled by photosynthesis because it is an energy source. Photosynthesis occurs in eukaryotic and prokaryotic organisms and some examples are humans, trees, and plants. Biological systems use photosynthesis as an energy source. Where there is a source of sunlight, there is a chance

Photosynthesis occurs in all green plants and is the beginning of nearly all food chains therefore a source of life to all living organisms. It is the process where plants transform light energy from the sun into chemical energy. By using light energy trapped by chlorophyll (light absorbing pigment), plants combine carbon dioxide and water to form glucose and oxygen.

Photosynthesis is essential to all living organism such as animals and plants. Photosynthesis is a process used by plants and other autotrophs to capture light energy and use it to power chemical reaction that converts carbon dioxide and water into oxygen, carbohydrates and water. (Textbook: Principles of Biology). The reactants and the products of photosynthesis are:

However, the photosynthetic process can be affected by different environmental factors. In the following experiment, we tested the effects that the light intensity, light wavelength and pigment had on photosynthesis. The action spectrum of photosynthesis shows which wavelength of light is the most effective using only one line. The absorption spectrum plots how much light is absorbed at different wavelengths by one or more different pigment types. Organisms have different optimal functional ranges, so it is for our benefit to discover the conditions that this process works best. If the environmental conditions of light intensity, light wavelength and pigment type are changed, then the rate of photosynthesis will increase with average light intensity and under the wavelengths of white light which will correspond to the absorption spectrum of the pigments. The null hypothesis to this would be; if the environmental conditions light intensity, light wavelength and pigment type are changed, then the rate of photosynthesis will decrease with average light intensity and under the white light which will correspond to the absorption spectrum of the pigments.

8) Steps 1 - 8 were repeated using the wavelengths of 360 nm to 900

For all living organisms including plants, respiration is the process of converting chemical energy into a usable form of energy (Biol 171L Lab 7). Even if an organism does not have an energy source, they will keep respiring. For autotrophic plants, the process of obtaining energy is called photosynthesis. It harvests solar energy, carbon dioxide, and water to form a usable form of energy (Tanaka 2009). The factors that go into this process includes the pigment the plant possesses, and the intensity, wavelength, and direction of the light. Plants that contain the pigment chlorophyll-a are the ones we see as the leaves of common trees, or grass.

Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special way of using the ATP they produce. Photosynthesis is a process where plants harness the sunlight they receive and they produce carbohydrates, as well as oxygen for living things and other plants. Now the sunlight ultimately powers the process of

     Photosynthesis is a reproductive system that occurs in plants. The main components required for photosynthesizing are sunlight, energy, water and mineral from soil, and carbon dioxide from the air. Once these components are combined they

     Photosynthesis is a biochemical process in which plant, algae, and some bacteria harness the energy of light to produce food. Nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. It is also responsible for producing the oxygen that makes up a large portion of the Earth¡¦s atmosphere. Factors that affect photosynthesis are light intensity and wave length, carbon dioxide concentration, and temperature.
