Can human breathing help plants to photosynthesize their energy?\nExplain.

Yes, they can. \nHumans produce carbon dioxide (CO2) through respiration: \nC6H12O6 + 6O2 --> 6CO2 + 6H20\nPlants then use the carbon dioxide in photosynthesis:\n6CO2 + 6H2O --> C6H12O6 + 6O2\n\nNote that C6H12O6 is glucose. \n\nHope that helps! =)

photosyntheses is the way plants make food. the plants make their food by getting sun, water and carbon dioxide and then the plant uses the carbon dioxide (which we breathe out) and lets out oxygen , without any plants we would run out of oxygen.

It works by prompting the patients lungs to start normal rythmic breathing on their own. It really is not the co2 that provides the help but the lung expansion is the reason it helps normal breathing on their own.

No, (or more correctly, not significantly) since the carbon dioxide being produced from the combustion was carbon that was already on the surface of the planet in one form or another (most likely as carbon dioxide the plant converted to glucose via photosynthesis).

Plants must have light to grow.  It doesn't necessarily have to be sunlight. Artificial light is a great to grow most plants too.  Photosynthesis is what causes plants to exchange necessary nutrients to create growth but each have unique abilities to utilize whatever light source is available.

Aerobic respiration.\n\nThe key is the "presense of oxygen" part.  Burning sugars in the absense of oxygen is anaerobic respiration.\n\nPhotosynthesis is definately wrong.  That's the capture of photons to boost low-energy electrons for the purpose of making energy, and sugar.

You have to remember plants did not cause the atmosphere to become oxygenic in the primordial days, cyanobacteria did. I'm guessing there are probably trillions of trees in the world.

photosythesis and aerobic cell respiration are REVERSE equations of each other and would probably be described as the TWO most important chemical equations on the planet, (but all equations are important!). Plants are crucial to aerobic life on earth!\n\nPHOTOSYNTHESIS is a synthesis reaction taking small inorganic molecules to make a larger organic molecule (and inorganic byproduct, oxygen. It occurs in the chloroplast of green plants (with chlorophyll pigment) and some photosynthetic bacteria:\n\nEQUATION in words, not formulas: \n\ncarbon dioxide plus water makes glucose sugar (carbs) and oxygen gas (but it needs the sunproper temp, chlorophyll and proper nutirents in the soil to occur\n\nAEROBIC CELL RESPIRATION is a catabolic-decomposition reaction where a larger organic molecule (glucose) is broken down into smaller inorganic molecules (CO2 and H2O) and occurs in the mitochondria of the cell, plant or animal:\n\nEQUATION IN WORDS, not formulas: \n\nglucose (in the presence of oxygen) converts to carbon dioxide, water, ATP (energy molecule) and heat. This is AEROBIC, not anaerobic.\n\nThus plants are able to "take care of themselves." They can make their own glucose from the sun, but then can do cell respiration from glucose they made from photosynthesis. We can't do photosynthesis, so we have to go eat carbs and are thus called heterotrophs.  It's why plants are called autotroph producers.  Anything that eats plants or animals is called a consumer or heterotroph.

I remember a girl in the news who ended up inhaling a piece of the X'nas tree and ended up getting a horrid asthma attack.  For years she lived with it until she was operated on about 10 years later.  After extracting the snall twig the leaf parts still had chlorophyll in it.

1. respiration is for animals, and phtosynthesis is for vegetals, bacteria and algae.\n\n2. We (animals) use respiration because our cells need a process called gas exchange ( we take Oxygen from the air and exchange it in our cells for carbon dioxide)\n\n3. This is possible for us because our cells have organs called mitocondria, while vegetal cells have chloroplasts.\n\n4.Photosynthesis is an important biochemical process in which plants, algae, and some bacteria harness the energy of sunlight to produce food. 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. Half of all photosynthesis comes not from plants, but from bacteria and algae.\n\nResìration involves the use of developed organs such as lungs.\n\n5. Photosynthesis produces energy from sun light, while\nrespiration produces energy from the Oxygen present in pur atmospheric air.

Carbon dioxide, because that is the raw material required for photosynthesis

Well, this happened once before.  Originally the earth had a very low concentration of atmospheric oxygen and oxygen was toxic to most organisms (they were all single celled back then).  But as organisms started to develop photosynthesis, oxygen was released into the atmosphere in huge amounts causing a massive extinction.  Now most organisms need or tolerate oxygen.  I'm not sure what would happen if the %O2 was increased now......I bet that plants wouldn't like it though.

They don't ALL release oxygen 24hrs a day guys! Oxygen is released during the process of photosynthesis. Photosynthesis requires sunlight. Is it bright and sunny in the middle of the night?! \nThat was a response to the previous answerers... I am sorry, I don't know the answer to your question! Perhaps it could relate to the photosynthetic pathway of the plant, eg C4 or CAM rather than just C3? That's just a random guess though. Good luck...

1. The leaves of a plant using photosynthesis...The leaves are healthy and green.\nSorry, but I thought that I could think of more than that, but I tried.

The simple answer to your question is -- Yes, continuous exposure to an energetic enough light source and adequate supply of water and carbon dioxide WILL prohibit cellular respiration from taking place.  The reason for this is found in the processes that take place during both photosynthesis and cellular respiration.  \n\nFirst, photosynthesis takes place in two phases 1) photophosphorylation (which needs light to take place) and 2) carbon fixation (Calvin cycle – which can occur in the light or dark).  During photophosphorylation, energy in the form of light is captured and stored as NaDPH and/or ATP.  This is also the stage that utilizes the H+ proton from water molecules and releases oxygen as a by-product.  During the Calvin cycle, the carbon in carbon dioxide is “fixed” or assimilated into other products and some ATP is utilized to for the building blocks for the plant, such as glucose.  As I said before, as long at a photosynthetic plant has light, water, and CO2 (and other trace minerals of course), photosynthesis will continue.\n\nSo where does cellular respiration come it, and do plants even do it?  The answer is, yes, they do use cellular respiration and they do it when they need an alternate energy source when light is not present.  Keep in mind that cellular respiration is something akin to the opposite of photosynthesis and its purpose is to supply energy in the form of ATP by breaking down things like glucose.  This provides the needed maintenance energy at the expense of stored energy in the glucose.\n\nSo, why would constant exposure to light keep a plant from respiring?  The answer is – the plant has a constant source of ATP through the photophosphorylation phase of photosynthesis that there is no need to break down its stored “fuel” to provide maintenance energy.  In fact, if enough light is provided, the resulting photosynthesis will provide enough energy to meet maintenance needs and allow generation of building blocks and stored fuel.\n\nAs for the second part of your question, there are many reasons that a plant in natural light for only daylight hours might grow better than one continuously lit artificially.  Most likely though, this has to do with the availability of the necessary “ingredients” for growth mentioned above.  Especially of interest here is the INTENSITY of the light rather than the duration.  However, even if the intensity is high enough, if the other ingredients are lacking relative to the natural environment the plant will still suffer.\n\nHope that clarifies the issue for everyone.

more plant cells.  photosynthesis (production of energy)+water+soil nutrients=plant cell reproduction and growth.
