transpiration

(noun)

the loss of water by evaporation in terrestrial plants, especially through the stomata; accompanied by a corresponding uptake from the roots

Examples of transpiration in the following topics:

  • Movement of Water and Minerals in the Xylem

    • Transpiration is the loss of water from the plant through evaporation at the leaf surface.
    • However, transpiration is tightly controlled.
    • Up to 90 percent of the water taken up by roots may be lost through transpiration.
    • Plants have evolved over time to adapt to their local environment and reduce transpiration.
    • These adaptations impede air flow across the stomatal pore and reduce transpiration.

  • Slipped-Strand Mispairing

    • This RecA-independent mechanism can transpire during either DNA replication or DNA repair and can be on the leading or lagging strand and can result in an increase or decrease in the number of short repeat sequences.

  • The Chemical Composition of Plants

    • As water vapor is lost from the leaves, the process of transpiration and the polarity of water molecules (which enables them to form hydrogen bonds) draws more water from the roots up through the plant to the leaves .

  • The "Noisy Minority" Effect

    • Most people's impression of the discussion up to that point will have been somewhat murky: "Huh, it sure feels like there's some big deal here, because there sure are a lot of posts, but I can't see any clear progress happening. " By explaining how the form of the discussion made it appear more turbulent than it really was, you retrospectively give it a new shape, through which people can recast their understanding of what transpired.

  • Transportation of Photosynthates in the Phloem

    • Water diffuses from the phloem by osmosis and is then transpired or recycled via the xylem back into the phloem sap .
    • Transpiration causes water to return to the leaves through the xylem vessels.

  • Leaf Structure, Function, and Adaptation

    • However, in plants that grow in very hot or very cold conditions, the epidermis may be several layers thick to protect against excessive water loss from transpiration.
    • They can also reduce the rate of transpiration by blocking air flow across the leaf surface .

  • Evaluate the Results

    • How the decision maker dealt with uncertainty or bias can be examined in the face of the results that have transpired.

  • The Disadvantages of Communism

    • However, what transpired was a nation ruled by corrupt Party officials, with no rights or civil liberty.

  • Evaporation

    • In hydrology, evaporation and transpiration (which involves evaporation within plant stomata) are collectively termed evapotranspiration.

  • Inorganic Nutrients and Other Factors

    • Wind can be an important abiotic factor because it influences the rate of evaporation and transpiration.
