A tree is made from air and water - is this true?

Answer 1

it would be a bit squidgy if that were true.

Answer 2

It is totally true ZAA my friend. Don't believe me?? Fly to big Island Hawaii and check out the OHIA tree sprouts growing on bare lava. This is proof in the pudding. Acids in the roots start breaking down the lava rock, but for the initial growth stages the tree is 'made from air and water'!!! I miss that sea air some time here in Eugene OR..

Answer 3

water is hydrogen and oxygen. air is mostly nitrogen, some oxygen, a little carbon (dioxide) and teeny amounts of other elements like hydrogen, helium and other stuff.

A tree contains a lot of cellulose which is the thing that makes the wood hard, and cellulose is carbon, hydrogen and oxygen. Also it is made up of proteins, which are made mostly of carbon, hydrogen, oxygen and nitrogen, so in this way the tree definitely is made of air and water. But the proteins also contain other elements which come from the ground, like sulphur, magnesium and potassium.

So if you want to say a tree is made of air and water , then it is, but in that case it is also made of rocks.

Answer 4

Almost

Photosynthesis uses air, water and sunshine to make glucose. This is the starting point for the cellulose, lignin and other carbohydrates needed to build your tree.

But

You need to add a few minerals into the equation so that the tree can make some of the proteins it needs.

Answer 5

A TREE IS MADE OF WOOD it requires air and water to grow just like we do basically apart from that it is still wood

Answer 6

Normally i would just say fruit, but i think both. I like the sugariness of the fruits but i love the essence and kick the produce bring

Answer 7

There are many healthy fruits and vegetables. Fresh vegetables like broccoli and green spinach contain calcium and are packed with fiber.

Answer 8

In the sense that it uses photosynthesis to make its food, and photosynthesis uses carbon dioxide and water, that would be true. However, organic compounds also need nitrogen, phosphorus, and sulfur, and we know that plants need many other trace elements. Even if these are taken into the plant dissolved in water, I wouldn't call them water.

So I think that air and water is pretty much simplified.

Answer 9

It consists largely of water and carbon dioxide, converted into cellulose by photosynthesis, free water acting as a solvent and much of the bulk of the cells and sap, nitrogen fixed from the atmosphere in the soil and converted into amino acids and proteins, but there are other substances in it which are brought into the tree in solution from water around the roots, notably sulphur in some of the amino acids and magnesium in the chlorophyll. There is also a variety of other substances in it, such as silica, phosphate ions, DNA, RNA, organic acids and various other substances depending on the species. Many of these are synthesised from carbon dioxide and water as well. They may include, for example, tannins, saponins, fixed and volatile oils, waxes, vitamins, hormones, flavonoids, alkaloids and many other substances. These are synthesised in processes involving trace elements such as calcium and enzymes. Therefore, although most of a tree is from the air and water as actual substances, and the rest is ultimately from other substances dissolved in water absorbed through the roots, not all of it is actually literally from air and water itself.

Answer 10

Most of a tree's biomass is made from water and carbon dioxide. The rest are from dissolved minerals in the soil.

Answer 11

Technically, yes - actually no. The air and water help the seed to germinate and grow. You need all 3 elements to make the whole.
