I. Photosynthetic organisms are those who convert the sun’s energy through a process called photosynthesis. They are also referred to as autotrophs. These organisms include plants, algae, and some bacteria. These organisms take in energy from the sun and water. They then complete the steps of photosynthesis and produce oxygen and glucose. All living organisms on earth require oxygen to survive. Plants provide a continuous supply of oxygen for these organisms. Without plants, there would be less oxygen molecules present in the atmosphere, creating a potential threat to organisms that require oxygen.
a. The photosynthetic organisms use their internal makeup to carry out the process of photosynthesis. Their makeup is different from that of organisms such as animals. Plant and algae cells contain chloroplasts where photosynthesis takes place. The light reactions of photosynthesis drive the transformation of solar energy into ATP. The chloroplasts of plants contain pigment molecules (chlorophyll) which are responsible for capturing the light from the sun. This energy is referred to as excitation energy. Once the excitation energy is detained, it is then transported throughout the chlorophyll molecules. The energy is taken to the reaction center; also know as a chlorophyll A molecule. Here, an electron from the energy is transferred from the reaction center to an electron receptor. The energy is now missing an electron. This causes the molecule to replace it with an electron from a water molecule, producing oxygen.
Once the electron is displaced from the reaction center, it is moved through the electron transport system. Through this phase, the energy from the electron is funneled into small amounts that can be used. These small amoun...

...f proteins is enacted by the release of ATP energy. Also, ATP is responsible for providing the energy to make muscular movements. The energy causes the muscle fibers to rub together and make the movements of the muscular tissue. Without a supply of glucose to make the ATP, these vital processes would not take place. This means that cells would not be able to maintain internal homeostasis. Their balance of molecules such as potassium and sodium would be thrown out of order. Also, it would not be able to make the proteins necessary and could not carry out the chemical processes needed. This would cause the failure of cells, resulting in the failure of the organism. This would also result in the organism’s inability to move the muscular tissue as well as the movement of cells. The immobility of cells would inhibit the performance of bodily functions.

Using A Process Called Chromatography Essay

- In this experiment we are using a process called “chromatography” in order to accurately identify and separate the photosynthetic pigments from one another. A small sample of spinach solution is placed onto chromatography paper and made contact with a solvent. The result of solvent as it moves through the paper due to capillary action are observed and recorded. The results show that both the sample and the solvent move along the chromatography paper at the same rate. As the sample moves through the paper, the sample begins to separate itself into different pigments....   [tags: Photosynthesis, Oxygen, Carbon dioxide, Ethanol]

A Study On Plant Photosynthesis Essay

- Plant photosynthesis happens in leaves and stems with green stem with a special organelle called a chloroplast. A plant leaf has tens of thousands of cells, and they contain 40-50 chloroplasts. The chloroplast, is an oval-shaped structure, and is divided by membranes into numerous disk-shaped compartments. The disk like compartments, which are called thylakoids, are placed vertically in the chloroplast and look like a stack of plates or pancakes. One stack of thylakoids is called a granum or more than one grana, the grana lie placed in a fluid known as the stroma....   [tags: Photosynthesis, Calvin cycle, Thylakoid, Atom]

The Stages Of Photosynthesis By Jan Van Helmont Essay

- Photosynthesis is when alive, green plants use sunlight to produce foods into carbon dioxide and water. Jan van Helmont is an individual who discovered photosynthesis. He realized there was something happening to the plant when water was being added. Jan van Helmont realized that the plant was beginning to get bigger. By Jan van Helmont doing this experiment, photosynthesis was discovered. The purpose of photosynthesis is so the plants can take in sunlight and chemically produce sugars. The sugars that the plant produces then break down the chemical bonds and turns it into energy for organisms to use....   [tags: Photosynthesis, Carbon dioxide, Metabolism]

Essay on Photosynthesis And Its Effect On Human Behavior

- Photosynthesis (an autotrophic function) converts light energy into chemical energy that can be utilized in the form of sugar and other organic compounds. The process of photosynthesis involves several steps of chemical reactions using carbon dioxide and water as reactants, in which photons of energy from light drive the reaction. The end products of photosynthesis are a sugar and oxygen that is released into the atmosphere. The chemical equation for photosynthesis is as follows: 6 CO2 + 6 H2O → 6(CH2O) + 6 O2 Zeroing in on the chemistry of photosynthesis reveals that the reaction is oxidation-reduction in that water is a proton donor (further, the electron donor of H)....   [tags: Photosynthesis, Calvin cycle]

Essay about How Does Photosynthesis Affect The Sensitivity?

- Photosynthesis is a process that consists of two sets of reactions, light reactions and light independent reactions. The light reactions occur in the chloroplasts on the membranes referred to as thylakoids. The thylakoid membranes participate in an electron transport chain to harvest energy from light, in the form of photons, and convert that energy into chemical energy such as adenosine triphosphate or nicotinamide adenine dinucleotide phosphate. (Mykles et al. 2016) The research conducted in the BZ 310-L06 laboratory analyzed the thylakoid membranes ability to perform photosynthesis by having run a series of experimental trials, that were modifications of the Robert Hill reaction, and then...   [tags: Photosynthesis, Adenosine triphosphate]

Essay on The Process of Photosynthesis

- Photosynthesis is the process undergone by plants consisting of a series of chemical reactions that require four factors; water, carbon dioxide, radiant energy and temperature using chlorophyll molecules to trap radiant energy from the sun resulting in the making of glucose and oxygen as bi-products. The process of photosynthesis provides plants with the food and energy they need to grow. Plants that produce their own food are called autotrophic plants. Not only do these plants make food for themselves but they also serve as primary producers....   [tags: plants, energy, chloroplast]

The Process of Photosynthesis Essay

- “Sunlight plays a much larger role in our sustenance than we may expect all the food we eat and all the fossil fuel we use is a product of photosynthesis, which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems” (Vermaas). This quote shows that photosynthesis is the most essential part of the exchange between humans and plants because it produces all the resources we need. When we sit down to eat fruit or vegetables, we usually don’t think about where those come from, how those grow up....   [tags: plants, energy, light]

How Does Photosynthesis Affect Our Own? Essay

- Taking all else into account, the single most important thing needed for life on earth to survive and exist is sunlight. The sun provides organisms with food, water and oxygen; all necessities in order for life to exist. Of course we cannot consume sunlight all on our own. Nor can we convert it into energy on our own. The process that makes it possible for us to benefit from sunlight is called photosynthesis. [1] Photosynthesis is chemical process in which plants capture energy from the sun, through components called chlorophyll, and use carbon dioxide (CO2) and water (H2O) to then convert the sunlight into glucose (C6H12O6)....   [tags: Photosynthesis, Adenosine triphosphate]

Process of Photosynthesis Essay

- Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules. Photosynthesis powers almost all trophic chains and food webs on the Earth. The net process of photosynthesis is described by the following equation: 6CO2 + 6H2O + Light Energy = C6H12O6 + 6O2 This equation simply means that carbon dioxide from the air and water combine in the presence of sunlight to form sugars, oxygen is released as a by-product of this reaction....   [tags: essays research papers]
