hi, just wondering, what happens to the rest of the water taken in?
:The rest of the water is used for photosynthesis (CO2+H2O+Light->O2+CH2O). Around 90-99 percent of the water is lost to transpiration. JackMontana (talk) 20:46, 4 December 2010 (UTC)
replies: text: Capillary action is not important in this process. The water column (in the xylem) is established from the very beginning of plant growth and the transpirational pull due to the water potential gradient (increasingly negative from root to stem to leaf to atmosphere) drives the entire process.

message: Isn't transpiration just the plant version of evaporation? Both involve organisms emitting water, both do it through pores, and one of the reasons that plants do it is to cool down, and animals mainly perspire to cool off. — Preceding unsigned comment added by 98.195.88.33 (talk) 23:10, 12 May 2016 (UTC)

replies: text: The number of stomata does not equate to stomatal conductance as you implied. Number of stomata needs to be expressed as stomata per unit area, and the terms 'stomatal density' or 'stomatal frequency' are widely used. A number of other parameters also need to be taken into consideration, notably the size of the stomatal opening. The role of stomata is already covered in the lead section and in the Regulation section There may be a case for strengthening what is said in these sections, but a new section covering the same points is not helpful. Furthermore the word effect was inappropriately used. Plantsurfer 10:29, 2 May 2017 (UTC)

message: Some actual transpiration rates are in a hundred-year-old source:
*Birch 67.9
*Lime 61.5
*Beech 56.6
*Maple 46.2
*Elm 40.7
*Oak 28.3
*Red spruce 5.8
*White pine 5.8
*Silver fir 4.4
*Austrian pine 3.2
Perhaps sample rates could be included?

message: The sentence "Transpiration is vital to the earth’s ecology and is being reduced by our decimation of the forests" is obviously not neutral. It needs to be fixed. --Firestar464 (talk) 06:17, 23 May 2022 (UTC)
replies: text: The statement is 100% accurate and correct.  What is "not neutral" about it? In Hawaii, for example, forests were cleared which turned the land arid; when the forests were replanted, the moisture returned and so did fresh drinking water.  There’s literally hundreds of examples of this in the literature. Viriditas (talk) 04:28, 6 June 2022 (UTC)
replies: text: Although the statement is correct, I removed it to restore the tag-less version.  Littering a page like this with useless tags is not a solution to anything.  This is basic ecology 101.  Nothing controversial or out of the ordinary here. Viriditas (talk) 04:32, 6 June 2022 (UTC)

message: How about the caveat that transpirational cooling also means higher humidity whether by plant, swamp cooler, or those fake mini ventless air conditioners? To some degree adding a tree canopy to an urban heat island could make both the temperature and dewpoint higher than before. B137 (talk) 02:46, 28 July 2023 (UTC)

message: Interesting article, but I would've liked to have seen information about when transpiration takes place.  Is it all the time?  Is it only at certain times of the day?  All the time, but some times are heavy and other times light?  Do different plants transpire at different times of the day?  Is the time of transpiration dependent on the light, humidity, or any other factor, including the interaction of other plants and animals with the plant?  Do some plants transpire less and then more, depending on the time of week or month or year or decade?  Does transpiration continue, to an extent, after the plant has died?  Does the rate of transpiration affect other factors about the plant?  Can there be so much water that the tree is unable to take enough of it into its roots that the soil becomes unstable?  Or, conversely, are trees able to suck up more water and transpire more when they realise that the soil is getting so wet its stability is affecting their continued prosperity.  (Sorry to use the bathetic fallacy there, but you get the point I'm sure.) 114.23.160.45 (talk) 05:37, 27 March 2024 (UTC)
