They're stored in compound forms. For example, Selenium might be stored as Selenium Carbonate, or Titanium might be stored in Titanium Dioxide. Plants use metals usually to store chemicals they plan to use later but can't store for an extended period in their normal forms.

Titanium was discovered in 1791 by Mr.Gregor, but it was not named until 1795.  It was first isolated by Hunter in 1910, by heating TiCl4 with sodium in a steel bomb at temperatures from 700-800 C.  That's pretty hot!\n\nTitanium is the ninth most abundant metal in the earth's crust.  That's a lot of titanium!\n\nIt is only about $6 to buy a pound of titanium. That's less than going to the movies! That's more like popcorn and pop at the movies.  heck, I'd just get some titanium.\n\natomic number: 22\n\natomic mass: 47.867 g\n\ncommon oxidation states: 2,3,4\n\nphysical appearance:  a beautiful lustrous white metal\n\nmelting point: 1660 degrees C \n\nboiling point: 3287 degrees C\n\ncrystal structure: hexagonal closest packed\n\n density: 4507 kg m3\n \n\nelectronegativity: 1.54 Pauling units\n\nground state electron configuration: [Ar]3d24s2

The seed is first planted. You will see little sprouts in one to two weeks. The plant will grow and start to flower. This flower will soon develop the tomato. Tomatoes are also classified as a fruit because they have seeds.\n\nLL.

Compounds are composed of two or more elements.\nElemental molecules are like the diatomic gases:\nF2, O2, N2, Cl2: composed of a single element.\nor the allotropes of sulfur :\n``Sulfur in the solid state ordinarily exists as cyclic crown-shaped S8 molecules. Sulfur has many allotropes besides S8. Removing one atom from the crown gives S7, which is responsible for sulfur's distinctive yellow color. Many other rings have been prepared, including S12 and S18. By contrast, its lighter neighbor oxygen only exists in two states of chemical significance: O2 and O3. Selenium, the heavier analogue of sulfur can form rings but is more often found as a polymer chain.´´

Most cans are steel cans which are covered by a thin layer of tin to prevent rust. The tin does get into your food. As far as I am aware this is independent whether the can is opened or not (unless oxidation or bacteria change the pH of the food inside, usually the lower the pH the more metal gets leached out). \nIt is arguable that once the can is open you can transfer the food into a different container, so no more tin will transfer to your food. The tin does not seem to be particularly dangerous in small amounts unless you happen to be sensitive to it. One website which discusses this is below, there will be more if you look for them. \nDifferent metals have different toxicity, and you definitely don't want to eat or drink more than you need to (the reason why you shouldn't really use hot water out of the faucet for cooking/drinking is that depending on the pipes and your boiler it will have more dissolved metals in than in cold water as heat speeds up the process). \n\nThere are also cans which are coated on the inside with something like plastic - as long as the food is not in contact with any metal it should be OK to store. \n\nA cover on your food is recommended as it slows bacteria to spread considerably, it does not have to be airtight in order to greatly reduce access of bacteria to your food. Bacteria float around in the air, so you may not want extra ones to settle on your food. (There are microbiological experiments with placing agar plates with bacterial growth media around and watch where you get most bacteria. If you place one next to a candle or any heating device you should get less, as the updraft of the air will not make it less likely that bacteria settle there. )\n\nSealing food airtight to preserve it is only useful if you sterilized your food before (e.g. by cooking it)\n\nHope these are enough bits and pieces of info...

The Sun is mostly hydrogen and helium, but also contains wery small quantities of lots of other elements such as oxygen, magnesium and iron.

Tomatoes contain high amounts of lycopene, which is effective in reducing the risk of prostate cancer in men.  As far as I know, tomatoes pose no cancer risk themselves.

All s, d, and f elements are metals.\n\nBlock p includes metals, non-metals, and some metaloids in between.  Metals include Aluminum and down in that group.  Tin and down in that group. and Polonium in its group.  So the lower left corner of the p block are metals and the upper right corner are non-metals.  Boron, Silicon, Germanium, Antimony, and Tellurium, tend to be considered metaloids.  (Depends on who you read.)

I heard somewhere, container of fertilizer, then place metal container on top, inside metal container, water I also heard it takes a little time.  btw, plastic container will not work

The plant kingdom, one of four eukaryotic kingdoms, is composed of multicellular, autotrophic organisms that photosynthesize to fix inorganic carbon (from atmospheric CO2) into organic molecules. Plants are the foundation of all terrestrial habitats, and serve as terrestrial Earth’s primary autotrophs, making organic molecules that will cycle through the food webs of most ecosystems. The photosynthetic capabilities of plants ultimately allow all terrestrial members of the animal kingdom to survive.\n\nOne hallmark of plant cells is the cell wall, which, in contrast to cell walls of single-celled organisms, is made of cellulose. The cell walls provide support for plant cells, as well as support and cohesiveness for plant tissue. Unlike the plasma membrane, the cell wall is not a semipermeable membrane, and so the shared cell walls between adjoining plant cells must have openings, plasmodesmata, to allow material transport and communication. Another distinguishing feature of plant cells is the large central vacuole, which stores a water reserve as well as essential chemicals, waste products of cellular metabolism, and sometimes other species-specific functions, such as storage of poisons or flower pigments. The central vacuole can also aid in cell growth by absorbing water.\n\nExcluding a few photosynthetic protists and cyanobacteria, plant cells are the only cells that contain chloroplasts. These organelles carry out the processes of photosynthesis, converting light energy into chemical energy and storing it as sugar. As well as producing food for ecosystems, photosynthesis releases oxygen molecules as byproducts, which replenish atmospheric oxygen used in cellular respiration and form a layer of ozone, O3, which shields the earth from solar ultraviolet rays.\n\nPlants probably evolved from multicellular green algae called charophytes and were the first multicellular organisms to colonize land. In order to do this, plants had to evolve several new characteristics in the form of distinct, specialized organs, which protists and algae lack. First of all, plants need to have a form of anchorage in the ground and rigid stem tissue for support. Thus, plants have developed root structures, which, in addition to anchoring a plant in the ground, allow the plant to take up chemical nutrients from the soil. Cellulose-containing cell walls developed in plant cells to maintain a form of rigidity in the part of the plant above ground. These account for the stiffness of plant stems and from the hardness of wood. Marine algae, which are suspended in water and can absorb nutrients from all around, have neither of these structures. Also, to prevent water loss in a terrestrial environment, plants evolved a waxy cuticle, which covers stem and leaf surfaces. Gases for photosynthesis can not diffuse across this cuticle, so tiny pores called stomata are present in the cuticle.\n\nBecause plants have organs that serve different functions, they must have systems to distribute necessary substances throughout the plant. Sugars, produced in photosynthesis, must be distributed to the body and roots of the plant that do not photosynthesize. Water and nutrients from the soil, taken up by the roots, must also make their way into the plant body and leaves. To perform these essential functions, plants contain a vascular tissue network, which consists small tubes running throughout the plant. There are two types of vascular tissue: xylem, which are small tubes dead cells that transport water and minerals up from the roots, and phloem, which are living cells that distribute sugars produced in photosynthesis.\n\nAlso characteristic of plants, as well as some algae, are gametangia that protect gametes. These are pockets of cells that protect the egg cell, and where the egg is fertilized.\n\nPlants have a life cycle unlike that of any animal, fungus, or bacteria. Probably a trait inherited from protistan (algal) ancestors, diploid and haploid generations alternate

nitrogen for vegetative growth\nphosphorous for flowering and root growth\npotassium for seed and protection from pests and frosts\nmagnesium to a plant is like iron to people whereas we have iron as the central molecule of our blood plants have magnesium in their circulatory system..\n\nIf you look at the list of minerals and micronutrients on a potent multivitamin you will see a list of trace elements that are both considered essencial for humas but also for plants which like all of those in various amounts depending on type of plant and additionally they also like boron.\n\nOb1

Fruits are basically storage "boxes" for various types of plants.  Nature has a way of developing the most efficient items methods for any given task.  The most efficient "box that can be made to store something is a sphere (round).\n\nThis is because the ratio of volume to surface area is higher than any other shape.  In other words, with the least waste of enrgy/material to build a container, the maximum product can be stored inside.  Thus, the natural evolution toward efficient design leads many of nature's energy storage devices (fruits) to have a round or near-round shape.

All living things are made up of Carbon, Hydrogen, Oxygen and Nitrogen so there will be plenty of these in the produce section of the grocery store.  \nAs for compounds try fructose sugar, sucrose sugar, sodium chloride salt, cellulose in the cell walls of fruit and veges.  \nIn the hardware store you can find the metal elements copper, zinc and aluminium.\nThere are also many many more but hopefully this helps.

1) is false, all the elements in living things can be found in non-living things\n\n2) this more tricky, what are these 4 elements most common in plants? I'm guessing: Hydrogen and Oxygen, (from water) Carbon, and . . .nitrogen???\nall these can be found in animals\nare you sure the question is asking about elements? elements in living things are pretty common to another. Its the compounds (hemoglobin, chlorophyll, etc) that get rather unique\n\ndo a little research, if some one cannot explain how they got the answer to a T/F question, you can't be sure they are just guessing

It stays (if it is able to!) in its atomic form. In fact it is highly reactive and therefore it is never found as a free element in the nature. It is normally kept under water at all times as it presents a significant fire hazard due to its extreme reactivity to atmospheric oxygen.
