An Introduction to Photosynthesis and Its Applications By Wim Vermaas Professor, Department of Plant Biology, and Center for the Study of Early Events in Photosynthesis Arizona State University wim@asu.edu http://www.worldandi.com/ The Basics. 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. Photosynthesis is carried out by many different organisms, ranging from plants to bacteria (Figure 1). The best known form of photosynthesis is the one carried out by higher plants and algae, as well as by cyanobacteria and their relatives, which are responsible for a major part of photosynthesis in oceans. All these organisms convert CO (carbon dioxide) to organic material by reducing this gas to carbohydrates in a rather complex set of reactions. Electrons for this reduction reaction ultimately come from water, which is then converted to oxygen and protons. Energy for this process is provided by light, which is absorbed by pigments (primarily chlorophylls and carotenoids). Chlorophylls absorb blue and red light and carotenoids absorb blue-green light (Figure 2), but green and yellow light are not effectively absorbed by photosynthetic pigments in plants; therefore, light of these colors is either reflected by leaves or passes through the leaves. This is why plants are green.

22. Autumn Leaves - Why Do Leaves Change Color In Fall? 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. http://photoscience.la.asu.edu/photosyn/education/colorchange.html

WHY DO LEAVES CHANGE COLOR IN THE FALL? by SCIENCE MADE SIMPLE Science Made Simple Science Subjects Science in the News Measurement Conversions PO Box 503, Voorhees, NJ 08043 I Can Read Word Puzzle Learn More About: How plants prepare for winter Projects We all enjoy the beautiful show of colors as leaves change each autumn. Did you ever wonder how and why this happens. To answer that question, we first have to understand what leaves are and what they do. Leaves are nature's food factories. Plants take water from the ground through their roots. They take a gas called carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into glucose. Glucose is a kind of sugar. 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. That means "putting together with light." A chemical called chlorophyll helps make photosynthesis happen. Chlorophyll is what gives plants their green color. As summer ends and autumn comes, the days get shorter and shorter. This is how the trees "know" to begin getting ready for winter.

23. Photosynthesis Energize plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. http://www.nhptv.org/natureworks/nwepphotosynthesis.htm

Plants need energy to survive just like you, but they get their energy from the sun. Energize Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose . Glucose is used by plants for energy and to make other substances like cellulose and starch . Cellulose is used in building cell walls. Starch is stored in seeds and other plant parts as a food source. That’s why some foods that we eat like rice and grains are packed with starch! True Colors Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun's energy and turns it into chemical energy. Not all the light energy from the sun is absorbed. Sunlight has many different colors in it. Chlorophyll usually absorbs red and blue light from the sun and reflects green light. It’s the green light reflecting that makes some leaves look green! In the fall, some plants stop producing chlorophyll and we see leaves change color. With the chlorophyll gone, the green light is not being reflected anymore. Home Episodes Nature Files Order ...

24. Photosynthesis plants need only light energy, CO 2 , and H 2 O to make sugar. The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll http://biology.clc.uc.edu/courses/bio104/photosyn.htm

Photosynthesis Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy, CO , and H O to make sugar. The process of photosynthesis takes place in the chloroplasts , specifically using chlorophyll , the green pigment involved in photosynthesis. Photosynthesis takes place primarily in plant leaves, and little to none occurs in stems, etc. The parts of a typical leaf include the upper and lower epidermis , the mesophyll , the vascular bundle(s) (veins), and the stomates . The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there. They serve primarily as protection for the rest of the leaf. The stomates are holes which occur primarily in the lower epidermis and are for air exchange: they let CO in and O out. The vascular bundles or veins in a leaf are part of the plant's transportation system, moving water and nutrients around the plant as needed. The mesophyll cells have chloroplasts and this is where photosynthesis occurs. As you hopefully recall, the parts of a chloroplast include the outer and inner membranes, intermembrane space

25. Types Of Photosynthesis C3 photosynthesis is the typical photosynthesis tha most plants use and that everyone learns about in school (it was all we knew about until a few decades ago http://wc.pima.edu/Bfiero/tucsonecology/plants/plants_photosynthesis.htm

plant terms flowering plant life cycle types of photosynthesis Tucson Mt. plants ... thumbnails by color TYPES OF PHOTOSYNTHESIS This page introduces you to photosynthesis and explains the three types of photosynthesis and their relevance for desert adaptation. Concepts Photosynthesis : the jamming together of CO (carbon dioxide) with H O (water) to make CH O (sugar) and O (oxygen), using the sun's energy. The sugar contains the stored energy and serves as the raw material from which other compounds are made. Respiration is the opposite of photosynthesis the stored energy in the sugar is released in the presence of oxygen, and this reaction releases the CO and H O originally jammed together by the sun's energy. Stomata : the "pores" in leaves (and stems) through which CO is taken in and O is released during photosynthesis. Plants control when stomata are open or closed and the width of the opening (formed by two guard cells that expand and contract to open and close the space between them). Transpiration : the water that evaporates out of stomata when they are open. This pulls more water and nutrients up to the top of the plant, but causes the plant to lose water and potentially dehydrate.

26. Photosynthesis In photosynthesis, light energy is converted into chemical energy. When animals and plants respire, the chemical energy in glucose can be converted into other http://www.sambal.co.uk/photosynthesis.html

Sambal's Science Web Photosynthesis Home Up Green plants are producers . This means that they can survive without animals! They can make lots of organic chemicals from a few simple inorganic chemicals. They need simple things like carbon dioxide and water and can make complex things like sugar, starch, fat, and proteins. Plants get their nutrients from the environment. Carbon dioxide comes from the air (unless they are aquatic plants, in which case they get it from the water surrounding them). They get water from the soil. They also need other inorganic nutrients like nitrate, sulphate and phosphate. A few plants cannot get nitrate out of the soil so they have to eat animals to get the nitrogen which they must have for growth. Animals are consumers ; they cannot carry out photosynthesis. This means that they have to eat other things to get the carbohydrates, fats, proteins, vitamins and minerals which they need. When plants are in the sunlight they can make a sugar called glucose. This is slightly different from the sugar (sucrose) which you put into your tea. Glucose contains three chemical elements: Carbon Hydrogen Oxygen All the carbon needed for photosynthesis comes from 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.

Primary Productivity of Plants Introduction The bodies of living organisms within a unit area make up a standing crop of biomass More specifically, biomass can be defined as the mass of organisms per unit area and is usually expressed in units of energy (e.g., joules m ) or dry organic matter (e.g., tons ha or grams m ). Most of the biomass in a community is composed of plants, which are the primary producers of biomass because of their ability to fix carbon through photosynthesis . This chemical reaction can be described by the following simple formula: O light energy C H O The product of photosynthesis is a carbohydrate , such as the sugar glucose , and oxygen which is released into the atmosphere ( Figure 9l-1 ). All of the sugar produced in the photosynthetic cells of plants and other organisms is derived from the initial chemical combining of carbon dioxide and water with sunlight (

Photosynthesis (the big picture) Anyhoo ... our topic right now, namely photosynthesis, is arguably one of the most important chemical reactions occurring on the planet. Let's see why. QUESTION ANSWER What is photosynthesis? Photosynthesis is a chemical reaction in which light energy is converted to chemical energy in glucose. It is the means by which the energy in sunlight becomes usable to living things. Living things can eat glucose, we can't eat sunlight. Exactly why is photosynthesis so important? Two big reasons. One product of photosynthesis is glucose (sugar), which provides the basis for most food chains. The second product of photosynthesis is oxygen which comes in handy if your happen to be an aerobic organism that requires oxygen for survival. Where does photosynthesis occur? This question can be answered on various levels. On the planetary level, most photosynthesis occurs in the oceans, because the oceans occupy the vast majority (70%) of the earth's surface. In terms of organisms, photosynthesis occurs in

Animals cannot make their own food out of air, so they depend on plants for their supply of food. Without plants, all the animals on Earth would die! Plants Make Food Plants make their own food by using a process called photosynthesis. During photosynthesis, plants trap light energy with their leaves . Chlorophyll in the leaves helps with photosynthesis. Plants use the energy of the sun to change water , nutrients from the soil and carbon dioxide into a sugar called glucose Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls. Animal cells do not have this cellulose. The cellulose enables plants to stand upright without a skeleton. Starch is stored in seeds and other plant parts as a food source. That's why some foods that we eat like rice and grains are packed with starch! Respiration Cycle Animals need to breathe oxygen to live. Plants need carbon dioxide to create their food.
