what is photosynthesis

Plants produce their own food through the process of photosynthesis. Photosynthesis takes place in chloroplasts, cells found in the leaves of a plant. It is a process that occurs in plants and some microorganisms and results in the production of sugars. Photosynthesis is the process by which green plants use sunlight to synthesise foods from carbon dioxide and water. photosynthesis definition: 1. the process by which a plant uses the energy from the light of the sun to produce its own food…. What Is Photosynthesis? Photosynthesis is the process by which plants make their own food using carbon dioxide, water and sunlight. Photosynthesis is usually represented by the equation 6 CO2 + 6 H2O + light --> C6H12O6 + 6 O2. photosynthesis synonyms, photosynthesis pronunciation, photosynthesis translation, English dictionary definition of photosynthesis. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. Photosynthesis is a biochemical process used by green plants, most algae, and cyanobacteria to capture energy from light and store it in chemical compounds that fuel biological functions. What is photosynthesis? Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. Overview of photosynthesis. See more. photosynthesis Has Greek Roots “Photosynthesis is the process used by green plants and a few organisms that use sunlight, carbon dioxide and water to prepare their food.” The process of photosynthesis is used by plants, algae and certain bacteria that convert light energy into chemical energy. The photosynthesis process is divided up into two steps.Some of these reactions happen in the light and other reactions occur in the dark. by Govindjee and Rajni Govindjee . Photosynthesis consists of both light-dependent reactions and light-independent reactions. The first step is a light-dependent reaction. Photosynthesis can also be seen as the reverse of respiration where the by-products of respiration are used as primary raw materials in photosynthesis. Carbon dioxide is a greenhouse gas. Photosynthesis literally means synthesis (or manufacturing) with light.It is the physiological process occuring in plants by which carbon dioxide (CO 2) and water (H 2 O), in the presence of visible light and chlorophyll, are converted to organic compounds which store chemical energy.It also occurs in other chlorophyll-containing organisms such as algae and cyanobacteria. By liberating oxygen and consuming carbon dioxide, it has transformed the world into the hospitable environment we know today. Chlorophyll gives plants their green colour. Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Photosynthesis is the process that enables plants to get energy from the sun. Define photosynthesis. The input is carbon dioxide (CO2), water (H 2O), minerals and light, and the output is carbohydrates (food) that we need for our nourishment, and oxygen that we need to breathe [Ref. How to use photosynthesis in a sentence. The sugars are used by the cell as energy, and to build other kinds of molecules. Photosynthesis is a universal mode of synthesis of glucose by the plants by consuming light and carbon dioxide to produce glucose and release oxygen. Light energy from the sun is converted into chemical energy by chlorophyll. Directly or indirectly, photosynthesis fills all of our food requirements and many of our needs for fiber and building materials. Photosynthesis, derived from the Greek words photo, meaning "light," and synthesis "putting together," is a process used by plants and some bacteria to harness the energy from sunlight to convert water and carbon dioxide to produce sugar (glucose) and oxygen. Photosynthesis is a chemical process through which plants, some bacteria and algae, produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy. The first section of the process is the absorption of light. Sunlight provides energy for the reaction. More Photosynthesis facts. Photosynthesis definition is - synthesis of chemical compounds with the aid of radiant energy and especially light; especially : formation of carbohydrates from carbon dioxide and a source of hydrogen (such as water) in the chlorophyll-containing cells (as of green plants) exposed to light. Photosynthesis - Photosynthesis - Photosystems I and II: The structural and photochemical properties of the minimum particles capable of performing light reactions I and II have received much study. Photosynthesis is very important for life on Earth.Green plants build themselves using photosynthesis. What photosynthesis accomplishes, why it's important, and how the light-dependent and light-independent reactions work together. The presence of too high levels of this type of gas in the air prevents heat from escaping. Photosynthesis Definition: Photosynthesis is a Greek word, wherein, Photo means light, synthesis means putting together. photosynthesis A. sunlight is absorbed by chlorophyll in a leaf B. carbon dioxide is taken in from the air C. water is transported from the roots D. Photosynthesis - definition of photosynthesis by The Free Dictionary . The photosynthesis can be defined as Photosynthesis is an anabolic process in which complex carbohydrates are synthesizes from simple substance like carbon di oxide and water in the presence of light by chlorophyllous cells of the plants and oxygen is a by products. Photosynthesis is the ultimate source of nearly all energy used in all living cells, plant or animal, as all activities of living cells, except photosynthesis, expend the energy provided by photosynthesis. As humans, in order to live plants, must take in gases. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die. Photosynthesis is arguably the most important set of chemical reactions on Earth. • Wood is a very important material used as fuel and in many fields including construction. The process combines 6 molecules of carbon dioxide and 6 molecules of water to produce one molecule of glucose and 6 oxygen molecules. Photosynthesis allows reducing the amount of carbon dioxide in the atmosphere in a natural way. IMPORTANCE OF PHOTOSYNTHESIS Photosynthesis and side products • Solar energy, transformed by photosynthesis, is the source of countless vegetable, animal and organic side products. Plants are known as “”autotrophs, which means organisms that can make their own food. Photosynthesis is a technique for converting sunlight into energy that has been utilized by certain organisms for around 3.4 billion years. Photosynthesis must occur in the presence of sunlight. Photosynthesis is the basic function of green plants: it enables them to transform light energy into chemical energy, which they can utilize in all cell activities. In order for photosynthesis to take place, it needs these three things: Water, carbon dioxide, and sunlight. Photosynthesis definition, the complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll. Photosynthesis is the process that transforms organisms from light energy into chemical energy. Treatment of lamellar fragments with neutral detergents releases these particles, designated photosystem I and photosystem II, respectively. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product. Plants use the energy produced during photosynthesis to grow flowers, fruits and seeds.Tree leaves and roots are used as ingredients in … Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. Photosynthesis occurs in the chlorophyll - the light-absorbing pigment within chloroplasts (the organelle where PS occurs). Photosynthesis is important because it provides two main things: food; oxygen; Some of the glucose that plants produce during photosynthesis is stored in fruits and roots. Photosynthesis is arguably the most important biological process on earth. For example, land plants use water from the soil, carbon dioxide from the air, and energy from the sun to synthesize glucose, which fuels plant growth, development and physiology. Photosynthesis allows plants, algae and certain bacteria to turn sunlight into chemical energy. Photosynthesis. Photosynthesis is a type of anabolic chemical reaction, which means that substances are created or synthesized from others. As a food coloring, chlorophyll is used to add a green color to pasta, the spirit absinthe, and other foods and beverages. Carbon dioxide and water are also needed for photosynthesis. Photosynthesis (photo = light and synthesis = to make) is the process plants use to change carbon dioxide and water into sugar using sunlight. On the other hand, especially the large forest areas, the plants do not stop absorbing this extra carbon dioxide. Photosynthesis converts massive amount of Sunlight into electrical and then chemical energy. What does Photosynthesis produce? In this sense, sunlight is captured by the chlorophyll of plants. Photosynthesis is a process in which the green plants use energy from the sun and produce glucose from carbon dioxide and water. Photosynthesis is a reaction in the LEAVES of a plant, where water and carbon dioxide become glucose (food for the plant) and oxygen (waste product). Photosynthesis is a chemical process by which plants, some bacteria, and algae convert energy derived from sunlight to chemical energy. | Biology | FuseSchool We wouldn’t have life without photosynthesis; life processes depend upon it. Chlorophyll is an essential pigment molecule for photosynthesis, the chemical process plants use to absorb and use energy from light.It's also used as a food coloring (E140) and as a deodorizing agent.
