Does the color of water change the growth rate of a plant?

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.

Depends on the plant.  Some plants, like kelp or Utricularia thrive when totally immersed.  Others cannot transpire properly unless their leaves are exposed to air, and will 'drown' in water.

Flowers which change color often do so based upon the acid or base content of the soil.\n\nThis might be the situation in your case.

No, it's purely dependent on the concentration of dissolved material in the water (usually limestone/calcium carbonate). The more dissolved limestone, the more rapid growth of stagtites/stalagmites.

I think when plant absorb water, or H2O, they use the H, or the hydrogen, and aspirate (or "exhale" in animal terms) the oxygen they take in as a liquid as a gas. The aspiration I believe is very slow and could take 100 plants 100 years, longer than the average lifespan of a human being, to see significant increases in oxygen levels.

Yes humidity does affect the growth of plants but the effect is greater in conditions of low humidity (dry).  When it is dry many plants will minimise opening of their stomata to reduce water loss this also has the effect of slowing gas exchange.  Plants need to take in CO2 for photosynthesis, if the stomata are closed this decreses the rate of photosynthesis and therefore the plant has less sugars created.  When the plant has less sugars (food) it can't grow as much.  \nSwamps can have the effect of flooding the root systems of plants so they don't work properly.  There are specially adapted plants that can survive in swamps, most can't.\nHope this helps

Vegetation emits in the infrared wavelength.  On false-color infrared mosaics, vegetation appears in red instead of green. The "redness" indicates vegetation density, type and whether growing on dry land or in a swamp. Grasslands appear light red, deciduous trees and croplands appear red, and coniferous forests appear dark red or maroon. Desert areas appear white and urban areas appear bluish green. Lakes, rivers and oceans appear in various shades of blue, dark blue for deep water and light blue for shallow or turbid water

Various plants have different accessory pigments in addition to chlorophyll.These various pigments are more efficient at using different wavelengths or under low or bright light conditions. For instance, many rain forest plants that live on the forest floor have a reddish undercoating to trap certain wavelengths of light. So, the various colors are adaptations to handle different growing conditions and allow the plant to grow adequately in areas where other plants cannot grow well.

Fascinating question. I would guess that under some conditions, then YES.\n\nMainly the closer to UV (bluer light) I would say could promote ripening and it would be the most like sunlight.\n\nripening of course being en-route to decay....

only if they are growing (the balance is called net photosynthesis rate). but when the conditions are not favourable for photosynthesis, they may get into "red numbers", negative net photosynthesis rate, like when they are wilting and/or it is too hot, they respire more than the photosynthesize. generally in temperate region water supply is the limiting factor, in sea it is the light that rapidly gets low when we get deeper.

Some water is essential for all plant growth, though necessary amounts vary for individual species. Too little water will cause the plant to wither and die, and too much water will waterlog the roots and rot them, killing the plant.

None, these are parasitic microbes and the colour of light falling on them has no effect. But if you beam un-filtered blue light which may have a substantial amount of UV lighht or UV light itself on microbes, they will die. Effect on growth will be the arresting of growth, as many genes are damaged. Efect on genes is the disruption of genes by UV light induced damage. And funnily, genes responsible for repair of UV induced damage will be switched on and will become most active genes in them during and for some time after UV light beaming.

When I was an undergraduate I did an experiment with some classmates in a blant biology lab class related to this question.  We collected soil from two areas: one area that received drainage from a local copper mine, and one close area that didn't receive the drainage.  We put the soil in water to extract the contents and used the water to water some wheatgrass seeds.  The grass watered with the extract of the drainage soil was different in color, shorter, and had fewer root hairs, as I recall.  In other words, it was less healthy.  In our experiment, then, the type of water definitely had an effect on the growth of the grass.

if a plant is in a windy area, evaporation happens faster. Or in not too bright of sun, photosynthesis happens faster.  Also, if it's well watered, the roots suck more in and push it through the plant.  \n\nThis probably won't help at all, since I have no idea of what you're really talking about, but someone once told me that they liked nothing more than attempted BS.

Try illuminating a growing plant (¿beans?) with different wavelengths (a simple set of filters -yellow, red and blue- will do) in black boxes. \nMeasure the length of the shoots under different light colors with time. \nWhat you should see: Blue should give the highest growth rate, due to the fact that the maximum absorption of the plants pigments falls on those wavelengths.

The water potential of pure water is defined as 0. Adding any solute makes the water potential negative. The more solute that is added, the more negative the water potential will become.\nIn osmosis, water moves from a less negative to a more negative water potential. Increasing the sucrose concentration in a tuber cell ought to increase the uptake of water, but it is not that simple because the water potential of plant cells depends upon both the solute concentration and the pressure exerted by the cell wall.\nAs the cell absorbs water, the pressure exerted by the wall increases. Eventually it will prevent the uptake of any more water and the cell will be turgid and have a water potential of 0.
