Where does photosynthesis happen?
479477
In green leaves, containing chlorophyll.\n\nPlants make their own food using a process called photosynthesis. During photosynthesis, the chlorophyll-containing green parts of the plant trap light energy and use it to perform a series of chemical reactions. The process involves carbon dioxide, and so plants also need plenty of air. We usually rely on the sun to provide light for our plants.

photophosphorylation, the light reactions, where the sunlight is exciting all the electrons. it's literally the electron transport chain plus some other stuff. electrons travel down a chain of proteins, releasing energy and creating ATP from ADP. however, in photosynthesis the electrons can go through it multiple times b/c they may be renergized by sunlight at the end. the electrons which aren't reenergized go on to the Calvin-Benson cycle. in respiration, at the end of the ETC electrons are used to form water.

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

light hits photosystem II in thylakoid membrane--> excites the electrons--> electrons move to carrier proteins-->electrons make it to photosystem I. but b/c electrons moved from photosysytem II to photosystem I there's an electron hole in photosystem II which is filled up by oxidizing water in the thylokoid space.\n\nhope it helps :) there's more than that but since u only asked photosystem II, i wont confuse u by giving other details.

Light reactions take place on the thykaloid membranes of the chloroplast. Light reaction requires light and water, and produces ATP and Oxygen. Dark reactions take place in the stroma (fluid that fills the chloroplast). It uses the ATP produced in light reactions to make glucose.

Although water is required for photosynthesis the amount of water actually required is tiny, almost immeasurable even in large tree. In contrast a large tree will use hundreds of gallons of water every single day. More importantly a plant that is in the dark will die without water just as fast as a plant in full sunlight. Since photosynthesis can't occur in the dark we know that it can't be photosynthesis that  most of the water is required for.\n\nPlants need water for three main reasons, the first two are  exactly the same reasons that you need water. \n\n1) Water serves as the solvent for every chemcial reaction that makes up life. Without water life simply isn't possible because no chemical reactions assocaited with life can occur.\n\n2) Water is also essential for transporting nutrients around the plant, so minerals are taken from the soil to the leaves dissolved in water, and sugars are taken from the leaves to the roots dissolved in water.\n\n3) Plants use water to maintain their very shape. The cells themselves are held in shape by the pressure of the water inside them, like water-filled balloons. Without water the cells shrink and collapse, and we see this as the plant wilting. If the collapse goes to far t5he cells tear and that part of the plant dies.

Photosynthesis 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 formaton of sugars or the fixation of nitrogen into amino acids, the building blocks for protein synthesis. Ultimately, nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. It is also responsible for producing the oxygen that makes up a large portion of the Earth's atmosphere. Organisms that produce energy through photosynthesis are called photoautotrophs. Plants are the most visible representatives of photoautotrophs, but it should be emphasized that bacteria and algae also contribute to the conversion of free energy into usable energy.

PHOTOSYNTHESIS: HOW LIFE KEEPS GOING...and going...and going...\nTake a little sunshine. Take some carbon dioxide molecules out of the air. \nTake some hydrogen atoms out of water. \nShuffle them around inside a bunch of little green chloroplasts inside green plant cells. What do you get? \nThat's right.  It's GLUCOSE and OXYGEN!   A couple of very important molecules. \n\nThat's what you asked, rite?? hee hee hee...;)

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 goes on in the chloroplasts\nphotosynthesis- make their own food by converting light energy into chemical energy

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 produces oxygen by combining CO2 and H2O to make glucose and O2. Cellular respiration (what plants do at night and what animals do) takes glucose and O2 and makes CO2 and H20. The answer is C.

I would say it is the leaf of a plant or the plant itself.  The leaf gives off oxygen (the waste product) during photosynthesis.\n\nOr: (I grabbed this off Wikipedia)\nphotosynthesis uses water as an electron donor which is oxidized into molecular oxygen by the absorption of a photon by the photosynthetic reaction centre.

Calvin cycle'''' (or Calvin-Benson cycle or carbon fixation) is a series of biochemical reactions that takes place in the stroma of chloroplasts in photosynthetic organisms. It was discovered by Melvin Calvin and Andrew Benson at the University of California, Berkeley. James Bassham also made important contributions to elucidating this pathway. It is one of the light-independent reactions or dark reactions.

Almost all plants absorb solar radiation and convert it to food using photosynthesis.

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.

Photosynthesis converts carbon from inorganic to organic states.  Then respiration converts carbon from organic to inorganic states.
