Photosynthesis requires a large array of pigments, enzymes, and other compounds to function.

Photosynthesis in turn requires energy from sunlight to drive the chemical reactions that produce organic carbon.

Photosynthesis changes sunlight into chemical energy, splits water to liberate O < sub > 2 </ sub >, and fixes CO < sub > 2 </ sub > into sugar.

Photosynthesis in cyanobacteria generally uses water as an electron donor and produces oxygen as a by-product, though some may also use hydrogen sulfide as occurs among other photosynthetic bacteria.

* Photosynthesis, a process whereby carbon dioxide and water are transformed into a number of organic molecules in plant cells.

Photosynthesis and production of epilithic algal communities in Thingvallavatn.

Photosynthesis takes place on the thylakoid membrane ; as in mitochondrial oxidative phosphorylation, it involves the coupling of cross-membrane fluxes with biosynthesis via the dissipation of a proton electrochemical gradient.

The Swedish Consortium for Artificial Photosynthesis, the first of its kind, was established in 1994 as collaboration between groups of three different universities, Lund, Uppsala and Stockholm, being presently active around Lund and the Ångström Laboratories in Uppsala The consortium was built with a multidisciplinary approach to focus on learning from natural photosynthesis and applying this knowledge in biomimetic systems.

This hub, the Joint Center for Artificial Photosynthesis, will receive up to $ 122 million in federal funding over five years.

Photosynthesis becomes possible in this range as well, for similar reasons, as a single molecule of chlorophyll is excited by a single photon.

Photosynthesis (; from the Greek, " light ," and, " putting together ", " composition ") is a process used by plants and other organisms to convert the light energy captured from the sun into chemical energy that can be used to fuel the organism's activities.

Photosynthesis occurs in plants, algae, and many species of bacteria, but not in archaea.

Photosynthesis is vital for all aerobic life on Earth.

Photosynthesis occurs in two stages.

Photosynthesis can occur under ice up to 100 m thick, and at the temperatures predicted by models equatorial sublimation would prevent equatorial ice thickness from exceeding 10 m.

Photosynthesis in Papyrus ( Cyperus papyrus L .), Photosynthetica.

" ( Photosynthesis was a poorly understood phenomenon in medieval and Renaissance times.

* F. M. Kelliher, M. B. Kirkham, J. E. Hunt, ' Photosynthesis and stomatal conductance of the New Zealand tree, Meryta sinclairii, grown under two watering regimes ' New Zealand Journal of Botany, 2000, Vol.

Photosynthesis occurs in two stages in a cell.

Photosynthesis is achieved using bacteriochlorophyll ( BChl ) c, d, or e, in addition to BChl a and chlorophyll a, in chlorosomes attached to the membrane.

Kalis can be seen skating the park in the following videos: Photosynthesis, The DC Video, and Time Code.

Photosynthesis by eukaryotic organisms can be traced back to endosymbiotic events in which non-photosynthetic eukaryotes internalized photosynthetic organisms.

Photosynthesis uses energy from sunlight to drive an autotrophic carbon fixation pathway.

Outdoor diving requires knowledge of the water depth and currents as conditions can be dangerous.

Extracting fresh water from a lens for human consumption requires careful calculation of the sustainable yield of the lens by season because each lens is susceptible to corruption by salt-water intrusion caused by overuse or drought.

Arranque has the same ingredients as gazpacho only that it requires less water and bread, making arranque into a gazpacho cream.

In all cases, melting of solid rock requires high temperature, and also water or other volatiles which act as a catalyst by lowering the solidus temperature of the rock.

These latter ingredients usually include sugar, fruit juice, or sugar substitutes ; they may be added and varied during preparation, or pre-mixed with the gelatin in a commercial product which merely requires the addition of hot water.

Cooking proper, as opposed to roasting, requires the boiling of water or oil in a receptacle, and was practised at least since the 10th millennium BC with the introduction of pottery.

It is extremely difficult to over water coir due to its perfect air-to-water ratio, plant roots thrive in this environment, coir has a high cation exchange, meaning it can store unused minerals to be released to the plant as and when it requires it.

In this situation, the ram is often useful, since it requires no outside source of power other than the kinetic energy of flowing water.

Liquid hydrogen has extremely low density ( 14 times lower than water ) and requires extensive insulation — whilst gaseous hydrogen requires heavy tankage.

This requires several independent nephron characteristics to operate: a tight hair pin configuration of the tubules, water and ion permeability in the descending limb of the loop, water impermeability in the ascending loop and active ion transport out of most of the ascending loop.

The extraction of target minerals by this technique requires that they be soluble, e. g., potash, potassium chloride, sodium chloride, sodium sulfate, which dissolve in water.

Sea-based transportation of any merchandise or persons shipped entirely or even partly by water between U. S. points — either directly or indirectly via one or any number of foreign points — U. S. Federal Law requires that said items or persons must travel in U. S .- built, U. S .- crewed, U. S .- citizen owned vessels that are U. S .- documented by the Coast Guard for such maritime " cabotage " carriage.

In this situation, the ram is often useful, since it requires no outside source of power other than the kinetic energy of flowing water.

In addition, the Act requires states to publish water quality standards for individual water bodies to provide additional protection where the national standards are insufficient.

Pushing electric current through a large resistance is like pushing water through a pipe clogged with hair: It requires a larger push ( voltage drop ) to drive the same flow ( electric current ).

However, since traditional-style cooking of soul food vegetables requires high temperatures and / or long time periods, the water-soluble vitamins ( e. g., Vitamins A and C ) are either destroyed or leached out into the water in which it is cooked.

Synchronized swimming demands advanced water skills, and requires great strength, endurance, flexibility, grace, artistry and precise timing, as well as exceptional breath control when upside down underwater.

The latter requires immersion in water for at least four minutes for the pain to be reduced to less than what would be accomplished using vinegar.

To produce food for the 6. 5 billion or so people who inhabit the planet today requires the water that would fill a canal ten metres deep, 100 metres wide and 7. 1 million kilometres long – that's enough to circle the globe 180 times.

To function properly, the body requires between one and seven liters of water per day to avoid dehydration ; the precise amount depends on the level of activity, temperature, humidity, and other factors.

Humans also use water for snow sports i. e. skiing, sledding, snowmobiling or snowboarding, which requires the water to be frozen.
