  2. Evapotranspiration - Wikipedia

    en.wikipedia.org/wiki/Evapotranspiration

    Evapotranspiration is a combination of evaporation and transpiration, measured in order to better understand crop water requirements, irrigation scheduling, [4] and watershed management. [5] The two key components of evapotranspiration are: Evaporation: the movement of water directly to the air from sources such as the soil and water bodies.

  3. Transpiration - Wikipedia

    en.wikipedia.org/wiki/Transpiration

    Transpiration of water in xylem Stoma in a tomato leaf shown via colorized scanning electron microscope The clouds in this image of the Amazon Rainforest are a result of evapotranspiration. Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.

  4. Photosynthesis system - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis_System

    Since photosynthesis, transpiration and stomatal conductance are an integral part of basic plant physiology, estimates of these parameters can be used to investigate numerous aspects of plant biology. The plant-scientific community has generally accepted photosynthetic systems as reliable and accurate tools to assist research.

  5. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Photosynthesis usually refers to oxygenic photosynthesis, a process that produces oxygen. Photosynthetic organisms store the chemical energy so produced within intracellular organic compounds (compounds containing carbon) like sugars, glycogen , cellulose and starches .

  6. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    The processes that drive these movements are evaporation, transpiration, condensation, precipitation, sublimation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid and vapor. The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation.

  7. Transpirational cooling (biological) - Wikipedia

    en.wikipedia.org/wiki/Transpirational_cooling...

    Of the 150 kWh falling on the crown, 1% is used for photosynthesis, 10% reflected as light energy, 5 to 10% as sensible heat with the remaining 79 to 84% entering the process of transpiration. [3] If a larger tree has a sufficient water supply, it can evaporate more than 100 L of water a day.

  8. Transpiration stream - Wikipedia

    en.wikipedia.org/wiki/Transpiration_stream

    There is also a pressure change between the top and bottom of the xylem vessels, due to water loss from the leaves. This reduces the pressure of water at the top of the vessels. This means water moves up the vessels. The last stage in the transpiration stream is the water moving into the leaves, and then the actual transpiration. First, the ...

  9. Vascular plant - Wikipedia

    Consequently, transpiration requires the plant to expend very little energy on water movement. Transpiration assists the plant in absorbing nutrients from the soil as soluble salts. Transpiration plays an important role in the absorption of nutrients from the soil as soluble salts are transported along with the water from the soil to the leaves.
