what 3 main things does the plant need for photosynthesis to occur?

Solar panels are used to artificially replicate the process of photosynthesis. While plants only convert light energy into sugars at an efficiency rate of about 3% – 6%, solar panels that are sold on the open market are able to convert light energy into electrical energy at an efficiency rate of 6% – 20% and up to 41% in an experimental setting. The technology used in solar panels is getting better and better every year and one day we may expect to use solar panels as our primary energy source. Keep in mind that enough light energy hits the Earth in one hour to compensate for all of Mankind's energy needs for an entire year. If we can someday harness 100% of this energy, we will have no need whatsoever for fossil fuels or alternative energy sources such as geothermal, alternative fuels, or wind power.
Plants also need water for photosynthesis. Photosynthesis is what plants do to create their food, and water is critical to this process. Water enters a plant's stem and travels up to its leaves, which is where photosynthesis actually takes place. Once in the leaves water evaporates, as the plant exchanges water for carbon dioxide. This process is called transpiration, and it happens through tiny openings in the plant's leaves, calledstomata. The water from the leaves evaporates through the stomata, and carbon dioxide enters the stomata, taking the water's place. Plants need this carbon dioxide to make food. Transpiration - this exchange of water for carbon dioxide - only occurs during the day when there is sunlight. This is why you might find dew on plants in the morning.
P lants are alive, just like people and animals
In ordinary language, people speak of “producing” or “using” energy. This refers to the fact that energy in concentrated form is useful for generating electricity, moving or heating objects, and producing light, whereas diffuse energy in the environment is not readily captured for practical use. Therefore, to produce energy typically means to convert some stored energy into a desired form—for example, the stored energy of water behind a dam is released as the water flows downhill and drives a turbine generator to produce electricity, which is then delivered to users through distribution systems. Food, fuel, and batteries are especially convenient energy resources because they can be moved from place to place to provide processes that release energy where needed. A system does not destroy energy when carrying out any process. However, the process cannot occur without energy being available. The energy is also not destroyed by the end of the process. Most often some or all of it has been transferred to heat the surrounding environment; in the same sense that paper is not destroyed when it is written on, it still exists but is not readily available for further use.
I think this because the plant may use up all of the carbon dioxide (Sodium hydro carbonate) and the plant can have as much light as it needs but if it does not have any carbon dioxide it will not be able to photosynthesise....
Living things all do certain things: They grow and die
Photosynthesis results in an increase in ; i.e. there is more carbohydrate in the plant. They can turn some of the glucose into fat or protein. They have to make lots of different chemicals to grow, but the two most important ones are fats and proteins. To do this they need energy (growth requires energy from glucose). Plants also have to make a very special chemical called DNA: this is the hereditary chemical of all animals and plants. They must also make lots of new chlorophyll.
Some animals are capable of using photosynthesis for short periods of time in order to gain the essential proteins they need to survive. These animals, most living on the bottom of the ocean floor, ingest algae and keep the chloroplasts in their bodies for several months at a time. The chloroplasts allow for photosynthesis to take place so that these animals may live. Animals that are capable of doing this include corals, sponges, sea anenomies, and slugs. It has been discovered, in fact, that slugs possess some of the genes that plants have which allow the chloroplasts to get the proteins that they need. It is even believed that chloroplasts themselves may have started out as a form of symbiotic bacteria that adapted itself to the conditions inside plant cells. Chloroplasts maintain their own DNA separate from the plant's DNA and resembles the DNA of some forms of bacteria.

Only plants can do photosynthesis.Photosynthesis is the process of harnessingenergy from sunlight to generate chemical energy,which can be stored and used later. Thisstored chemical energy comes from the conversionof inorganic carbon (carbon dioxide) into organiccarbon, or food. Every living thing needs a sourceof stored energy for survival, even plants! Thinkof the stored energy as a battery, which isproviding energy not just for muscle movement(which plants obviously don't worry about), butfor all of the essential processes of life (cellgrowth and repair, for example). Living thingsthat can not harness and store energy themselvesthrough photosynthesis (and this includes humans,animals, insects, bacteria, viruses) HAVE to usethe energy harnessed and stored by plants tosurvive, or their battery runs out. Only plantshave the ability to recharge the batteries, soliving organisms are dependent on plants. Theprocess that releases the energy stored in thesebatteries is called the Krebs cycle.

Photosynthesis converts these energy- depleted compounds (ADPand NADP+) back to the high energy forms (ATP and NADPH) and theenergy thus produced in this chemical form is utilized to drivethe chemical reactions necessary for synthesis of sugars andother carbon containing compounds (e.g., proteins, fats). Theproduction of high energy ATP and NADPH in plants occurs in whatis known as Light Phase Reactions (Z Scheme) (requiressunlight). The energy releasing reactions which converts themback to energy-depleted ADP and NADP is known as Dark PhaseReactions (Calvin Cycle) (does not require light) in whichthe synthesis of glucose and other carbohydrates occurs.
are factors that can limit the rate of photosynthesis
The Z Scheme diagram shows the pathway of an electron fromwater (lower right) to NADP+ (upper left). It also shows theenergy relationships which are measured as voltage potentialshown on the scaleon the right. To raise the energy of theelectrons derived from water (+0.82 volts) to the level necessaryto reduce NADP+ to NADPH (-0.32 volts), each electron must beboosted twice (vertical red arrows) by light energy absorbed inPhotosystems I and II. After each boosting , the energizedelectrons flow "downhill" (diagonal black lines) and inthe process transfer some of their energy to a series ofreactions which ultimately adds a phosporus to ADP to producehigh energy ATP and reduces NADP+ to NADPH. There is analternative shunt whereby the electron flow turns back tocytochrome b563 (green line)and this is called and it occurs when there is no need for NADPH, so onlyATP is produced.
