Photosynthesis

• Photosynthesis is a process that occurs in the leaves of a plant and needs both chlorophyll and light energy. • During photosynthesis, the chlorophyll in leaves help convert carbon dioxide and water into the products oxygen and glucose. • The product glucose acts as a vital source of food for the plant. • Carbon dioxide, water and light are all needed for photosynthesis to take place. Plants get carbon dioxide from the air through their leaves, and water from the ground through their roots. Light energy comes from the Sun. The oxygen produced is released into the air from the leaves. The glucose produced can be turned into other substances, such as starch and plant oils, which are used as an energy store. This energy can be released by respiration. It's hugely important these pitches are absolutely pristine for the fans, the spectators, for the players, it's incredibly important. We have to have a safe surface so they're not getting injured, missing a shot, costing your team a chance for a win, the chance for a trophy. I'm Nathan Scarff, and I'm the Head Groundsman in Derby County Football Club. Working inside a stadium, we have a really big shade issue. The darkest area in this pitch will never see any sunlight. The plants struggle to photosynthesise naturally, so we use the lights to effectively synthetically induce the photosynthesis process and create the growth, so it gives the plant a lot of light energy and also some heat as well to encourage growth. We are lookin...

Discover how glucose and oxygen produced during photosynthesis in plants helps during respiration in animals As has been stated, carbohydrates are the most-important direct organic product of photosynthesis in the majority of green plants. The formation of a simple carbohydrate, Little free glucose is produced in plants; instead, glucose units are linked to form see Not only carbohydrates, as was once thought, but also amino acids, proteins, 2) and organic compounds. More energy is required to break the bonds between oxygen and other elements (e.g., in Evolution of the process Learn how the layered arrangement of chlorophyll molecules within a leaf within a leaf while increasing increasing Primitive coloured cells then had to evolve mechanisms for using the light energy absorbed by their pigments. At first, the energy may have been used immediately to initiate reactions useful to the The first oxygenic (oxygen-producing) cells probably were the There are a number of photosynthetic Factors that influence the rate of photosynthesis The rate of photosynthesis is defined in terms of the rate of oxygen production either per unit mass (or area) of green Light intensity and temperature As has been mentioned, the complex mechanism of photosynthesis includes a photochemical, or light-harvesting, stage and an enzymatic, or carbon-assimilating, stage that involves chemical reactions. These stages can be distinguished by studying the rates of photosynthesis at various degrees of light...

• Outer and inner membranes— protective coverings that keep chloroplast structures enclosed. • Stroma—dense fluid within the chloroplast. The site of conversion of carbon dioxide to sugar. • Thylakoid—flattened sac-like membrane structures. The site of conversion of light energy to chemical energy. • Grana—densely layered stacks of thylakoid sacs. Sites of conversion of light energy to chemical energy. • Chlorophyll—a green pigment within the chloroplast. Absorbs light energy. Dark reactions occur in the stroma. Carbon dioxide is converted to sugar using ATP and NADPH. This process is known as carbon fixation or the Calvin cycle. The Calvin cycle has three main stages: carbon fixation, reduction, and regeneration. In carbon fixation, carbon dioxide is combined with a 5-carbon sugar [ribulose1,5-biphosphate (RuBP)] creating a 6-carbon sugar. In the reduction stage, ATP and NADPH produced in the light reaction stage are used to convert the 6-carbon sugar into two molecules of a 3-carbon Photosynthesis Summary In summary, photosynthesis is a process in which light energy is converted to chemical energy and used to produce organic compounds. In plants, photosynthesis typically occurs within the chloroplasts located in plant leaves. Photosynthesis consists of two stages, the light reactions, and the dark reactions. The light reactions convert light into energy (ATP and NADHP) and the dark reactions use the energy and carbon dioxide to produce sugar. For a review of photosynthes...

• Understand the meaning of photoautotroph in reference to plants. • Explain how the energy from light is converted into carbon-based chemical energy and building blocks in plants. • Identify where in the plant the various photosynthetic reactions take place. • Explain how the carbon-based building blocks move to other parts of the plant and are used for energy, storage, and structures. Photoautotrophs Plants are autotrophs, meaning that they are self-nourishing (Greek autos = self and trophe = nutrition). Specifically, plants are photoautotrophs, because they use the energy from light to produce organic molecules with which they build their cells and store energy. Organic molecules are compounds associated with living organisms that contain carbon atoms. It was once thought that organic molecules could only be synthesized in nature by living organisms through the intervention of a “life force.” This hypothesis was disproved in 1828 when urea, a simple organic compound, was synthesized in a laboratory. Since that time, a major branch of chemistry, organic chemistry, has arisen to study and synthesize organic molecules. In contrast to organic compounds, inorganic compounds were historically defined as those lifeless minerals that are dug up from the ground. Note that this chemical definition of organic (containing carbon atoms) has little or no relationship to the contemporary use of the word to describe a method of producing food. Organic food production, by regulation, re...

Cells get nutrients from their environment, but where do those nutrients come from? Virtually all organic material on Earth has been produced by cells that convert energy from the Sun into energy-containing macromolecules. This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains (Figure 1). Plants exist in a wide variety of shapes and sizes. (A) Coleochaete orbicularis (Charophyceae) gametophyte; magnification x 75 (photograph courtesy of L. E. Graham).

Photosynthesis consists of a number of photochemical and enzymatic reactions. It occurs in two stages. During the light-dependent stage (“light” reactions), chlorophyll absorbs light energy, which excites some electrons in the pigment molecules to higher energy levels; these leave the chlorophyll and pass along a series of molecules, generating formation of NADPH (an enzyme) and high-energy ATP molecules.
