B.  Donating electrons to photosystem II.\n\nSee discussion of water photolysis in the first source given below.\n\nAnswer A is wrong because NADPH is already reduced, and doesn't "want" any more electrons.  NADP+ is the oxidized form, which reacts with the electrons and hydrogen ions produced by the photolysis of water to form NADPH.\n\nAnswers C and D are wrong because water is an electron donor (not an electron acceptor)  in photosynthesis.  Water is photolysed, producing molecular oxygen, hydrogen ions, and electrons:\n\nH2O -> 2H+ + 2e- + 0.5O2

Photosynthesis (photo=light, synthesis=putting together), generally, is the synthesis of sugar from light, carbon dioxide and water, with oxygen as a waste product. It is arguably the most important biochemical pathway known; nearly all life depends on it. It is an extremely complex process, comprised of many coordinated biochemical reactions. It occurs in higher plants, algae, some bacteria, and some protists, organisms collectively referred to as photoautotrophs.\n\nPhotosynthesis uses the energy of light to make the sugar, glucose. A simple general equation for photosynthesis follows.\n\n6 CO2 + 12 H2O + light → C6H12O6 + 6 O2 + 6 H2O\ncarbon dioxide + water + light energy → glucose + oxygen + water\nPhotosynthesis occurs in two stages. In the first phase light-dependent reactions or photosynthetic reactions (also called the Light reactions) capture the energy of light and use it to make high-energy molecules. During the second phase, the light-independent reactions (also called the Calvin-Benson Cycle, and formerly known as the Dark Reactions) use the high-energy molecules to capture carbon dioxide (CO2) and make the precursors of glucose.

Photosynthesis is the process by which plants convert carbon dioxide and water to glucose for energy. It takes place in the cholorplasts of the cell, which contain chlorophyll. There are two parts to photosynthesis, the light reactions, and the dark reactions, or the Calvin cycle. In the light reactions, light energy triggers electrons to form ATP and NADPH from ADP and NADP through the electron transport chain. This part also takes water and releases oxygen.\n\nIn the calvin cycle, RuBP uses carbon dioxide to create glucose, which is the energy the plant needs to function. \n\nThe products released from photosynthesis are water and oxygen.

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.

Process by which green plants and certain other organisms transform light into chemical energy. In green plants, light energy is captured by chlorophyll in the chloroplasts of the leaves and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds (simple and complex sugars) that are the basis of both plant and animal life. Photosynthesis consists of a number of photochemical and enzymatic reactions. It occurs in two stages. During the light-dependent stage (light reaction), 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. Oxygen, released as a by-product, passes into the atmosphere through pores in the leaves. NADPH and ATP drive the second stage, the dark reaction (or Calvin cycle, discovered by Melvin Calvin), which does not require light. During this stage glucose is generated using atmospheric carbon dioxide. Photosynthesis is crucial for maintaining life on Earth; if it ceased, there would soon be little food or other organic matter on the planet, and most types of organisms would disappear.\n\n\n\n    6 CO2 + 12 H2O + light → C6H12O6 + 6 O2 + 6 H2O\n\n    Carbon Dioxide + Water + Light energy → Glucose + Oxygen + Water

Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.\n\nPhotosynthesis is an important biochemical process in which plants, algae, and some bacteria convert the energy of sunlight to chemical energy. The chemical energy is used to drive synthetic reactions such as the formation of sugars or the fixation of nitrogen into amino acids, the building blocks for protein synthesis.

Water is the basic solvent in the nature .In its presence only the biochemical reactions takes place(like photosynthesis, respiration, fat metabolism)\nAbove all water gives turgidity to plants ,with out water plants will wilt  and die, this is what happens when u do not water the plant for a long time

Photosynthesis occurs in chloroplast in all eukaryotic green cells eg:All higher plants and in chromatophores in prokaryotic green cells suchas Nostoc,Anabaena etc.. \nDuring photosynthesis radiant solar energy is converted into chemical energy.\nUsing light energy carbondioxide is reduced into carbohydrates. The source of hydrogens for the reduction of carbon dioxide is from water. same light energy is useful in splitting water molecules, as a result oxygen comes into the atomosphere & hydrogen for reduction of corbondioxide

Photosystems I and II in plant cells both absorb light energy from the sun to perform photosynthesis. Neither system absorbs green wavelength of light, which is why plant leaves look green.\nPhotosystem I absorbs 700 nanometer wavelengths the best while Photosystem II absorbs 680nm wavelengths the best.\n\nIn Photosynthesis, Photosystem II comes before photosystem I. (the numbering is mixed up because P1 was discovered before P2). First, in P2, water is split by light energy and the electrons released by the reaction travel to an electron acceptor which produce ATP. P1 does the same thing as P2 but in addition, its electron acceptor also receives the electrons used by P2.\n\nThese two photosystems make up the light reaction part of photosynthesis. The energy (ATP) made in this reaction drives the dark reaction part of photosynthesis, where carbon dioxide is converted to glucose sugar.

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, CO2, and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll, the green pigment involved in photosynthesis. \n\nPhotosynthesis 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!\n\nWe can write the overall reaction of this process as: \n\n6H2O + 6CO2 ----------> C6H12O6+ 6O2\nMost of us don't speak chemicalese, so the above chemical equation translates as:\n\nsix molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen\n\n\nDiagram of a typical plant, showing the inputs and outputs of the photosynthetic process.

A leaf may be viewed as a solar collector crammed full of photosynthetic cells.\n\nThe raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.\n\n\nCross section of a leaf, showing the anatomical features important to the study of photosynthesis: stoma, guard cell, mesophyll cells, and vein. Image from Purves et al., Life: The Science of Biology, 4th Edition, by Sinauer Associates (www.sinauer.com) and WH Freeman (www.whfreeman.com), used with permission.\n\nWater enters the root and is transported up to the leaves through specialized plant cells known as xylem (pronounces zigh-lem). Land plants must guard against drying out (desiccation) and so have evolved specialized structures known as stomata to allow gas to enter and leave the leaf. Carbon dioxide cannot pass through the protective waxy layer covering the leaf (cuticle), but it can enter the leaf through an opening (the stoma; plural = stomata; Greek for hole) flanked by two guard cells. Likewise, oxygen produced during photosynthesis can only pass out of the leaf through the opened stomata. Unfortunately for the plant, while these gases are moving between the inside and outside of the leaf, a great deal water is also lost. Cottonwood trees, for example, will lose 100 gallons of water per hour during hot desert days. Carbon dioxide enters single-celled and aquatic autotrophs through no specialized structures.\nVirtually all oxygen in the atmosphere is thought to have been generated through the process of photosynthesis. Obviously, all respiring organisms (including plants) utilize this oxygen and produce CO2. Thus, photosynthesis and respiration are interlinked, with each process depending on the products of the other. The global amount of photosynthesis is on the order of a trillion kg of dry organic matter produced per day, and respiratory processes convert about the same amount of organic matter to CO2. A large part (probably the majority) of photosynthetic productivity occurs in open oceans, mostly by oxygenic prokaryotes. Without photosynthesis, the oxygen in the atmosphere would be depleted within several thousand years. It should be emphasized that plants respire just like any other higher organism, and that during the day this respiration is masked by a higher rate of photosynthesis.
