Biochemical Cycles Elmhurst College Carbon Cycle Phosphorus Cycle ... Click for larger image Carbon Cycle Carbon Cycle - Photosynthesis: Photosynthesis is a complex series of reactions carried out by algae, phytoplankton, and the leaves in plants, which utilize the energy from the sun. The simplified version of this chemical reaction is to utilize carbon dioxide molecules from the air and water molecules and the energy from the sun to produce a simple sugar such as glucose and oxygen molecules as a by product. The simple sugars are then converted into other molecules such as starch, fats, proteins, enzymes, and DNA/RNA i.e. all of the other molecules in living plants. All of the "matter/stuff" of a plant ultimately is produced as a result of this photosynthesis reaction. An important summary statement is that during photosynthesis plants use carbon dioxide and produce oxygen Click for larger image Carbon Cycle - Combustion/Metabolism Reaction: Combustion occurs when any organic material is reacted (burned) in the presence of oxygen to give off the products of carbon dioxide and water and ENERGY. The organic material can be any fossil fuel such as natural gas (methane), oil, or coal. Other organic materials that combust are wood, paper, plastics, and cloth. Organic materials contain at least carbon and hydrogen and may include oxygen. If other elements are present they also ultimately combine with oxygen to form a variety of pollutant molecules such as sulfur oxides and nitrogen oxides.

You must have Javascript enabled to see this menu. DNR Home Bay grasses or submerged aquatic vegetation (SAV) are vascular plants that live underwater and are found through-out Maryland’s tidal and non-tidal waters. Approximately fifteen varieties of bay grasses are typically found in the Chesapeake Bay and surrounding bodies of water. Unlike terrestrial plants which have rigid stems and leaves, bay grasses have specialized cells which provide buoyancy in the water environment. Bay grasses serve many important ecological roles such as improving water quality, providing food and shelter for other species as well as stabilizing sediment at the bottom of the water column. Recent declines in water quality in the Bay caused by excess nutrients and sediment has caused significant losses of bay grass populations. Because of their importance, the restoration of bay grasses in the Chesapeake and Coastal Bays is a priority for Maryland DNR as well as the other Bay partners.

15. Fact Sheet - Paper And The Forest During photosynthesis plants make sugars such as glucose which quickly changeinto starch. Light energy, in the presence of chlorophyll, promotes a reaction http://www.paper.org.uk/info/factsheets/photosynthesis.htm

FACT SHEET Photosynthesis and the Paper Industry What is Photosynthesis? Plants and trees are living organisms. They need food and nutrients in order to grow. Animals obtain their nutrients by eating but plants cannot do this. They have a special way of making their own food. It is called photosynthesis. There are four main factors involved in photosynthesis: During photosynthesis plants make sugars such as glucose which quickly change into starch. Light energy, in the presence of chlorophyll, promotes a reaction between carbon dioxide and water vapour that leads to the production of glucose. Oxygen gas is released as a by-product and diffuses out of the plant into the atmosphere. Subscribe Un-Subscribe This is a very simplified account of what happens. It actually consists of at least 50 different reactions in sequence. Essentially the light energy enables the water to split into hydrogen and oxygen atoms. The hydrogen atoms then combine with the carbon dioxide to form glucose and more water. So light is only needed in the initial stages of photosynthesis. Click for larger picture The Role of Leaves in Photosynthesis Green leaves are the principal part of a plant which carry out photosynthesis in daylight hours. In daylight, the mesophyll absorbs carbon dioxide and releases oxygen as the photosynthesis process occurs. The sugar made in the leaves is transported away by the phloem sieve tubes to to growth and food storage areas of the plant. In bright light, plants often produce more sugar than can be removed by the phloem. The excess sugar is stored in leaves as starch grains. These remain in the leaf until night when they are re-converted into sugar and transported from the leaf. The presence of starch in a leaf is evidence that photosynthesis has taken place.

In so doing, photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen, on which most organisms depend. Photosynthesis occurs in green plants, seaweeds, algae, and certain bacteria. These organisms are veritable sugar factories, producing millions of new glucose molecules per second. Plants use much of this glucose, a carbohydrate, as an energy source to build leaves, flowers, fruits, and seeds. They also convert glucose to cellulose, the structural material used in their cell walls. Most plants produce more glucose than they use, however, and they store it in the form of starch and other carbohydrates in

PHOTOSYNTHESIS Table of Contents What is Photosynthesis? Leaves and Leaf Structure The Nature of Light Chlorophyll and Accessory Pigments ... Links What is Photosynthesis? Back to Top Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP , the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll . Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive. Oh yes, we need the food as well! We can write the overall reaction of this process as: O + 6CO H O Most of us don't speak chemicalese, so the above chemical equation translates as: six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen Diagram of a typical plant, showing the inputs and outputs of the photosynthetic process.

Your browser does not support script World Builders™ Session Four Microbiology Photosynthesis: Capturing Energy Photosynthesizing organisms build themselves using the carbon in carbon dioxide. Living organisms must concern themselves with two things capturing energy and reproducing their kind. On this page we will learn about how photosynthetic organisms capture energy and make food. We tend to think that everything green and alive on the earth is a plant. This is not precisely true. The first photosynthetic organisms were bacteria, and they are still with us today and still pumping out oxygen. These tiny organisms are prokaryotes, and they made all higher life on the earth possible by altering the atmosphere so that it contained oxygen. Great among the photosynthetic bacteria are the cyanobacteria, which are still providing a good part of the earth's oxygen.
