where does the carbon in the cell walls, dna, etc come from?  the dirt or the CO2 in the air?

The plants do not 'eat' anything the way animals eat and digest and then defecate.\n All green plants ( with out exception) have unique mechanism of Photosynthesis by means of which they prepare what they want. We, the animals, rob them of the things they have manufactured.In this case Man is more guilty than the other animals as he gives them practically nothing in return.\nThe CARBON in your question is absorbed by them from the surrounding air during photosynthesis. The equation is as follows:-\n6CO2 + 12H2O-> LIGHT&CHLOROPLAST> = C6 H12 O6 + 6H2O + 6O2\nThus carbondioxide gas(6CO2) and water(12H2O) combine together in the presence of sunlight and chloroplst to produce glucose(C6 H12 O6) , water and oxygen gas (6O2). this gas is realeased in the atmosphere!\n The CO2 gas and water is available to mankind easily but can we produce glucose? No way.This reaction will require plenty of energy for our machinary, and the veture will be immpracticable. There in lies the greatness of the Plant Kingdom!\nThe Glucose thus manufactured is then put to innumerable application by thes plants including cell wall formation and DNA synthesis.\n Other mineral requirements are absorbed by them from the soil along with water.\n lastly  CO2 + water in the hands of man = Soda water But\n         CO2 + water in the hands of Plants = Sugar.

Maybe the tree of life is rooted to the 'nutrient soil?' What I mean is that organic compounds were thought to form before any cell. They provided the nutrients for these early cells, so my best guess is that they would be your roots.

Prior to there being any life, all the carbon on Earth was in the form of simple molecules that form without living things. Amino acids, single nucleotides, a few sugars. \n\nImagine if one took all the living things in the world, and all the formerly living things that are now coal, gas and oil, and broke them down into those simple original molecules. Now dissolve all that into the oceans.\n\nWhat you would have is a weak broth. Weak, but very nutritious. If a single modern bacteria was released in this broth, it would easily take over the Earth. \n\nEven a much simpler form of life than a modern bacteria would be able to multiply in the primordial soup. One could see competition between these lifeforms, minimal at first, escalate into war once most of the nutrients were used up. Evolution would then favor the development of more complexity.

Basically as the apple is left on the table with air, the air will react with the apple and carbon is produced. The process is called oxidation.

CO2. and you can also use vinegar.

Nucleus contains the genetic material and is where mRNA is produces for later production of protein, which occurs at the rough endoplasmic reticulum.  THe mitochondria carries out respiration, while the chloroplast does the same using light. There are a number of others, of course, but that'll get you started.

What carbon? Your ashes are mostly calcium. The carbon is all converted to CO2 and goes up the smokestack.

Several points can be made but two will suffice for now.\n\n1. Carbon based does not only apply to humans but to every part of the biosphere (living part of the environment). Our whole ecosystem is based on carbon!\n\n2. Carbon IS as essential to life as Oxygen. What is the gas we give off when we exhale? CARBON dioxide! We must take in carbon to passit out.\n\nOur bodies "burn" sugars to get the energy our bodies neen to run. Guess what the main element in sugar is? Yes, you're right! CARBON! Carbon is in every cell of our bobies.

In Photosynthesis, plants use the sun's energy as light to transform carbon dioxide and water into glucose.  In cellular respiration,  glucose is ultimately broken down to yield carbon dioxide and water, and the energy from this process is stored as ATP molecules.

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.

Oxygen is made as a result of photosynthesis only.\n\nGlucose is also made as a result of photosynthesis.\n(Or due to the breakdown of fats, or complex sugars.)\n\nCarbon Dioxide is produced as a result of cellular respiration.\n\nThe source of energy released from glucose is the bond energy between the carbons in the molecule and the reductive properties of the electrons in the bond.\n\nCellular respiration occurs is parts.\n\nGlycolysis occurs in the cell cytoplasm (cytosol).  The Krebs cycle occurs in the mitochondrial matrix.\nThe electron transport chain and oxidative phosphorylation occurs at the inner membrane of the mitochondria.

Photosynthesis typically describes how plants produce sugar by using Light, Carbon Dioxide, and Water.  Oxygen is a waste product.

the by-products are light energy and heat energy.\nthe mass is not equal, since some carbon content is lost to air in the form of oxides of carbon( which are gases)
