I have no idea what rocketman is on about (or on?)\n\nPlant-plant communication is called allelopathy: it is a chemical process plants use to keep other plants out of their space.\n\nChemicals that impose allelopathic influences are called allelochemicals. They are usually secondary plant metabolites, which are generally considered to be those compounds (such as alkaloids, phenolics, flavonoids, terpenoids and glucosinolates) which do not play a role in primary metabolic processes essential for a plant's survival and are produced as byproducts of primary metabolic pathways. Allelochemicals are present in virtually all plant tissues, including leaves, flowers, fruits, stems, roots, rhizomes, seeds and pollen.

Many Organic compounds affected the environment,hydrocarbons , Oil and its derivatives , like gasoline. Flour anted Chloris carbon compounds like Freon affect the ozon layer.Pesticides affect the environment by its toxicity to humans and animals.Organophosphorous compounds are very toxic and used as ware fare agents.Most of organic compounds are carcinogenic when they used un properly.

INTRODUCTION\nPollution, contamination of Earth’s environment with materials that interfere with human health, the quality of life, or the natural functioning of ecosystems (living organisms and their physical surroundings). Although some environmental pollution is a result of natural causes such as volcanic eruptions, most is caused by human activities.\n\nThere are two main categories of polluting materials, or pollutants. Biodegradable pollutants are materials, such as sewage, that rapidly decompose by natural processes. These pollutants become a problem when added to the environment faster than they can decompose (see Sewage Disposal). Nondegradable pollutants are materials that either do not decompose or decompose slowly in the natural environment. Once contamination occurs, it is difficult or impossible to remove these pollutants from the environment. \n\nNondegradable compounds such as dichlorodiphenyltrichloroethane (DDT), dioxins, polychlorinated biphenyls (PCBs), and radioactive materials can reach dangerous levels of accumulation as they are passed up the food chain into the bodies of progressively larger animals. For example, molecules of toxic compounds may collect on the surface of aquatic plants without doing much damage to the plants. A small fish that grazes on these plants accumulates a high concentration of the toxin. Larger fish or other carnivores that eat the small fish will accumulate even greater, and possibly life-threatening, concentrations of the compound. This process is known as bioaccumulation.\n\nTYPES OF POLLUTION\nPollution exists in many forms and affects many different aspects of Earth’s environment. Point-source pollution comes from specific, localized, and identifiable sources, such as sewage pipelines or industrial smokestacks. Nonpoint-source pollution comes from dispersed or uncontained sources, such as contaminated water runoff from urban areas or automobile emissions.\n\nThe effects of these pollutants may be immediate or delayed. Primary effects of pollution occur immediately after contamination occurs, such as the death of marine plants and wildlife after an oil spill at sea. Secondary effects may be delayed or may persist in the environment into the future, perhaps going unnoticed for many years. DDT, a nondegradable compound, seldom poisons birds immediately, but gradually accumulates in their bodies. Birds with high concentrations of this pesticide lay thin-shelled eggs that fail to hatch or produce deformed offspring. These secondary effects, publicized by Rachel Carson in her 1962 book, Silent Spring, threatened the survival of species such as the bald eagle and peregrine falcon, and aroused public concern over the hidden effects of nondegradable chemical compounds.\n\nA  Air Pollution \nHuman contamination of Earth’s atmosphere can take many forms and has existed since humans first began to use fire for agriculture, heating, and cooking. During the Industrial Revolution of the 18th and 19th centuries, however, air pollution became a major problem. As early as 1661 British author and founding member of the British Royal Society John Evelyn reported of London in his treatise Fumifugium, “… the weary Traveller, at many Miles distance, sooner smells, than sees the City to which he repairs. This is that pernicious Smoake which fullyes all her Glory, superinducing a sooty Crust or Furr upon all that it lights.…”\n\nUrban air pollution is commonly known as smog. The dark London smog that Evelyn wrote of is generally a smoky mixture of carbon monoxide and organic compounds from incomplete combustion (burning) of fossil fuels such as coal, and sulfur dioxide from impurities in the fuels. As the smog ages and reacts with oxygen, organic and sulfuric acids condense as droplets, increasing the haze. Smog developed into a major health hazard by the 20th century. In 1948, 19 people died and thousands were sickened by smog in the small U.S. steel-mill town of Donora, Pennsylvani

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.

Further to Dave Stark's answer :\n\nAgent Orange was the generic name given to a cocktail of defoliants used in Vietnam. Within the mix was :\n\n2,4D [ 2,4 dichlorophenoxyacetic acid - present as the amine salt or ester depending on application]\n\n2,4,5-T [2,4,5-trichlorophenoxyacetic acid - present as the amine salt or ester depending on application]\n\nTCDD [ Tetrachlorodibenzodioxin ] TCDD is formed when the reaction used to manufacture 2,4,5-T from 2,4,5-trichlorophenol and acetic anhydride is allowed to overheat. This changes the selected endproduct from 2,4,5-T to TCDD. The 2,4,5-T used in the production of agent orange was not suitable for sale in the US [as the level of TCDD was about 10000 times higher than was acceptable for "domestic" sale] so was used by the armed forces as a defoliant for "remote areas".\n\nThe mode of action of the phenoxyacetates is as "auxins" - synthetic plant hormones - which modify the way plants grown and use nutrients.\n\nGlyphosate is a glycine derivative -  (N-(phosphonomethyl) glycine, C3H8NO5P)  to be specific. Its mode of action is to interfere with the enzyme EPSPS.

I'm not really sure what they are looking for.  There are many different results that can occur.  It also depends on how much of the plant is cut and removed, when in the plants life cycle you make the cut, which part of the plant you cut off, etc.  I would guess that they are looking for a difference in vertical shoot growth.  If the apical (the top of the main stem) meristem is removed this will cause lots of lateral growth and branching.  This happes because the auxin hormone is no longer able to go to the apical meristem so it it activates lateral bud growth.  Another thing that might happen depending on plant type is that you might get sucker growth.  This happens when too much of the photosynthetic material is removed.  The roots then start to send up suckers which are new stems growing off of the existing root system.  This is most common in trees and will only happen in woody plants.

It is possible that the color of the water absorbed by the plant could tint the leaves darker than the leaves would be if the plant absorbed clear, colorless water.  This might effect the growth rate.\n\nAlso, the color of the water could be due to a chemical that affects growth rate, so in this case, yes the rate could be affected.

I won't do your homework for you, but I will give you a few hints.\n\nThe first hint is that ddnight is talkin' smack. This has nothing to do with atmosoheric composition.\n\nThe second hint is that you should be looking very varefully at the relative effect of C4 and CAM utilisation on water LOSS. Underline the word 'loss".\n\n--------------------\n>>>CAM plants and C4's do better in higher temps than C3's.\n\nGenerally yes. But the question is why the plants died in that order. Begonia are tropical plants, so a temperature would not have killed it, and the pineapple is both tropical nad C4, sdo temperature effects can't be at play directly.\n\nOnly one plausible explanation remains.
