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). The oxygen released from the reaction is also contributed by the water in the reactant. Therefore, carbon dioxide serves as the electron acceptor, thus being reduced, while water is oxidized because it donated that electron.
To fully grasp the processes allowing photosynthesis to occur, one must understand plant (and ultimately the chloroplasts within plant cells) anatomy. Photosynthesis occurs in the leaves of a plant. Zooming in on the leaves to a cellular level, there are 5 important structures within chloroplast anatomy. An outermembrane holds the organelle’s

Cyanobacteria, being the oldest fossil on Earth, began as a prokaryotic cell with a nucleoid, that eventually evolved to infold along the cell. An aerobic proteobacterium was ingested and eventually evolved into mitochondria in the cell OR as cyanobacterium. These eukaryotes went on to accommodate capability of photosynthesis via chloroplasts (versus mitochondria). As a comparison, it can be said that chloroplasts and mitochondria perform opposite functions. The physiology of chloroplasts builds glucose from carbon dioxide, water, and light. The function of mitochondria breaks down glucose to make ATP for
Photosynthesis consists of the following equation: Sun light Carbon dioxide + Water = = == == ==> Glucose + Oxygen Chlorophyll Chlorophyll is a substance found in chloroplasts, found in the cells of leaves.
This chemical is used to catch the light energy needed in photosynthesis. They take carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into glucose. Plants use glucose as food for energy and as a building block for growing. The way plants turn water and carbon dioxide into sugar is called photosynthesis.
Experiment #1: The purpose of this experiment is to investigate the effects of baking soda and light intensity on the rate of photosynthesis of green spinach leave through the observation of floating disk.
An Analysis and Evaluation of Data from Photosynthesis Experiments Graph analysis This is my analysis for the investigation in to the affect of light intensity on the rate of photosynthesis to the Canadian pondweed, elodea. In the results the pattern is that when the light intensity is higher the readings are generally higher. On the graph the less the light intensity the lower the gradient of the curve. the equation for the photosynthesis process is; CO2 + 2H2O + Light Energy = =
Before learning about photosynthesis, I thought this was just a way for plants to grow, not knowing the full detail that goes on inside the plant for it to grow. So, after learning about what photosynthesis is and how it truly works, it is something that is remarkable and how plants are really the only living thing that uses this process. Photosynthesis is the process of taking in carbon dioxide (CO2), which is a gas that is exhaled from animals and goes into the air and is absorbed into a plant, water (H2O) which is absorbed through the roots of a plant or known as capillary action, sunlight is absorbed through chloroplasts which contain chlorophyll or better known as the leaves of the plant. With the photosynthesis process, the plant can create a by-product known as oxygen gas which is released through the little pores into the atmosphere (Simon, Dickey, Hogan & Reece, n.d.).
The process of photosynthesis is present in both prokaryotic and eukaryotic cells and is the process in which cells transform energy in the form of light from the sun into chemical energy in the form of organic compounds and gaseous oxygen (See Equation Below). In photosynthesis, water is oxidized to gaseous oxygen and carbon dioxide is reduced to glucose. Furthermore, photosynthesis is an anabolic process, or in other words is a metabolism that is associated with the construction of large molecules such as glucose. The process of photosynthesis occurs in two steps: light reactions and the Calvin cycle. The light reactions of photosynthesis take place in the thylakoid membrane and use the energy from the sun to produce ATP and NADPH2. The Calvin cycle takes place in the stroma of the chloroplast and consumes ATP and NADPH2 to reduce carbon dioxide to a sugar.

Chlorophyll in the cells in the palisade layer absorb light for photosynthesis. The plant releases the oxygen created in photosynthesis back into the air but it uses or stores the glucose for energy, respiration, growth and repair. The leaves and plants are also specially adapted for photosynthesis in their structure and cell alignment.

Chloroplasts are and organelle that contains chlorophyll, and is the place where photosynthesis takes place. In a basketball stadium, the concession stands are like chloroplasts. The concession stands is like chloroplast because it makes food for everyone at the game. This is how chloroplasts and the concession stands are alike because they both make food.
C3 photosynthesis is the ancestral form of photosynthesis and is present in the majority of plant species (Sage, Sage & Kocacinar 2012). In this process CO2 enters the mesophyll cell (mc) via openings in the epidermis called stomata and diffuses into the into the chloroplast where it enters the Calvin cycle (Raven, Evert & Eichhorn 2013). The Calvin cycle is made up of three stages: 1. Carboxylation of Ribulose-1,5-bisphosphate (RuBP). In which a molecule of CO2 is covalently bonded to a molecule of RuBP forming the first stable intermediate 3-Phosphoglycerate. It is from this 3 carbon product that the name C3 photosynthesis comes from. This reaction catalysed by the enzyme Ribulose-1,5-bisphosphate carboxylase-oxygenase (Rubisco) 2. Reduction of 3-phosphoglycerate to the carbohydrate glyceraldehyde-3-phosphate, utilizing the ATP and NADPH formed in the light harvesting reactions. 3. Regeneration of the initial substrate RuBP (Taiz & Zeiger 2006). These stages encompass thirteen different reactions the net result of which is:
Photosynthesis is a process in plants that converts light energy into chemical energy, which is stored in bonds of sugar. The process occurs in the chloroplasts, using chlorophyll. Photosynthesis takes place in green leaves. Glucose is made from the raw materials, carbon dioxide, water, light energy and oxygen is given off as a waste product. In these light-dependent reactions, energy is used to split electrons from suitable substances such as water, producing oxygen. In plants, sugars are produced by a later sequence of light-independent reactions called th...
This organelle is the site of photosynthesis in plants and other organisms. In the structure, the chloroplasts has a double membrane, the outer membrane has a continuous boundary. This organelle can be found in a vast group of organelles called the plastid, chloroplasts are usually found in many plant cells but never in animal cells. Chloroplasts organelles are large; they are 4-10um long and 2-3um wide. They are very important to plants because chloroplasts are what plants use to create food from sunlight. Chloroplasts are not found in humans.
In some way, shape, or form energy is one of the several reasons why there is an existence of life on earth. Cellular respiration and Photosynthesis form a cycle of that energy and matter to support the daily functions that allow organisms to live. Photosynthesis is often seen to be one of the most important life processes on Earth. Photosynthesis is a process by which plants use the energy of sunlight to convert carbon dioxide and water into glucose so other organisms can use it as food and energy. It changes light energy into chemical energy and releases oxygen. This way organisms can stay alive and have the energy to function. Chlorophyll is an organelle generally found in plants, it generates oxygen as a result too. As you can see without
The Importance of Photosynthesis and What it Does for Life According to scientists, life is “the condition that distinguishes animals and plants from inorganic matter, including the capacity for growth, reproduction, functional activity, and continual change preceding death, also the way of life of a human being or animal. ”("Life,”) In order for one to have life, one must have the nine characteristics to be considered a living thing. These nine characteristics are: all living things are made up of cells, living things are able to reproduce, living things use energy, maintain homeostasis, respond and adapt to the environment, grow and develop, have a life span, evolve over time, and are interdependent. All of the nine characteristics have one thing in common, something that is needed for all living things to work, even if they do not know it.
An Experiment to Investigate the Effect of Light Intensity on the Rate of Photosynthesis. Introduction Photosynthetics take place in the chloroplasts of green plant cells. It can produce simple sugars using carbon dioxide and water causing the release of sugar and oxygen. The chemical equation of photosynthesis is: [ IMAGE ] 6CO 2 + 6H20 C 6 H12 O 6 + 6O2 It has been proven many times that plants need light to be able to photosynthesize, so you can say that without light the plant would neither photosynthesize nor survive.
