how do we depend on photosynthesis?

photoautotrophs (plants) reduce carbon, every other organism oxidizes it.  without photosynthesis, this world is dead.

simply put: saccarides and oxygen.\nbut there are 2 types of photosynthesis and one works during the day and the other at night and its really complicated. also, one is done in a liquid suspension and the other in these disc-like structures in the chloroplast.

I'm always happy to help out a Van Halen fan! Anyway, photosynthesis is the process by which plants convert sunlight into energy and fuel to grow, and also to manufacture proteins, the most important of which is chlorophyll, which gives plants their green color. They also convert this light into sugars anfd starches, which they need to grow. (The storing of these sugars, in fact, along with the slowing down of the photsynth, is what gives those autumn leaves their great colors.)  During the dark hours the plants are basically dormant, and thus no photosynth taking place, but they are still respirating, i.e. taking in carbon dioxide and releasing oxygen. They do this in light too, of couse, but at a faster rate. But just like we need our sleep, the plants need the dark also to rest and store their food, otherwise they would expend it all and thus dry out, which is why they get yellow (depleted chlorophyl) with too much sun.

Photosynthesis:\n\nCO2 + chlorophyl + sun light + water + minerals + energy -> O2 + food + water\n\n6 CO2 + 12 H2O + ATP + NADPH -> C6H12O6 + 6 O2 + 6 H2O \n\ncarbon dioxide + water + energy -> carbohydrate (glucose) + oxygen + water\n\nGreen plants and livings have chlorophyl make photosynthesis between sun rise and sun set.\n\nRespiration:\n\nC6H12O6 + 6 O2 -> 6CO2 + 6H2O + ATP\n\ncarbohydrate (glucose) + oxygen -> carbon dioxide + water + energy\n\nAll livings have respiratory system.

Plants can sustain photosynthesis (and release oxygen) from any lightsource that has enough energy. But plants can also get stressed by too much light and actually get sick. They might also grow in unnatural ways, like growing sprouts all over, if "fed" the wrong amount of light for too long periods of time. \n\nPlants are tuned to natural light during ordinary hours but some plants can even "OD" on sunlight. When the sun shines too hot during a hot day they sometimes shutdown photosynthesis and begin to perspire. \n\nIt all comes down to what kind of plant it is. An ordinary house plant should release oxygen if the artificial light is not too intensive.

b\nbecause photosynthesis is a anabolic process whereby the plant uses simple material to synthesis hexose sugar like glucose

Photosynthesis is about 1% efficient while we can make PV cells about 20% efficient.\n\nThis is yet another case of nature being inferior to human technology.

Chlorophyll. It needs the presence of sunlight too.

plants require visible spectrum for photosynthesis. the light you can see is the light they can use. green is least effective. red and blue are most.

Hmmm. Here goes:\n\nPlants need carbon dioxide, water and sunlight.\n\nHumans need oxygen, water and everything else.

In simplest terms, photosynthesis is an anabolic pathway and uses light energy to generate ATP which in turn is used for biosynthesis to make glucose storing the energy derived as glucose. It also consumes CO2 and produces O2. While respiration is a catabolic pathway deriving energy from complete metabolism of glucose to CO2 and water using oxygen in the process.

Photosynthesis is the process that all green plants use to convert water and nutrients with the aid of chlorophyll\nand energy from sunlight into food(glucose).\nrespiration is only part of the process that allows all living things(including plants) to produce energy via andosine triphosphate breakdown to grow, move and reproduce. respiration is the process of transporting air(oxygen)into the body to allow breakdown of food into energy and waste products\ngirl, you need more confidence in yourself.\ni don't have a major in biology, infact i only have what you call high school education.\nsome people may want to fool you.\nGod bless,\ngabe\nps, algae is a plant, it may be single celled , but still a plant.

In photosynthesis, plants convert light into chemical energy. This energy is thus used to turn carbon dioxide into carbohydrate releasing oxygen as a byproduct. That is why many plans to fix global warming such as the Kyoto Protocol aim to increase the number of forested areas through so-called carbon sinks.

What is Photosynthesis? 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!\n\n-------------------------------------------------------------\nSuagr and Oxygen is produced. I think thats right.

The eyespot helps the organism find sunglight to power photosythesis and the chloroplast allows the organism to carry out photosthesis when light is available. \nThey work together because the eyespot finds sunlight which allows the cholorplast to allow the organism to carry out photosythesis. \nHope this helps!

Photosynthesis 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.\n\nIn the light-dependent reactions the pigment chlorophyll absorbs light and loses an electron that travels down an electron transport chain producing the high energy molecules NADPH and ATP. The chlorophyll molecule regains its electron by taking one from water, a process that releases oxygen gas.\n\nIn the Light-independent or dark reactions the enzyme RuBisCO captures CO2 from the atmosphere and in a complex process called the Calvin-Benson cycle releases 3-carbon sugars which are later combined to form glucose.\n\nPhotosynthesis may simply be defined as the conversion of light energy into chemical energy by living organisms. It is affected by its surroundings and the rate of photosynthesis is affected by the concentration of carbon dioxide, light intensity and the temperature.
