  • soil
  • This is because the plants cells would naturally lose essential mineral ions by osmotic diffusion back into the soil moisture. (docbrown.info)
  • Therefore, active transport systems must be used by the plant to counteract the natural direction of diffusion from a high mineral concentration in the plant cells to a low mineral concentration in the soil moisture. (docbrown.info)
  • In these environments, slower but more efficient transpiration increases biomass yield and prevents or delays the exhaustion of soil water and onset of leaf senescence. (frontiersin.org)
  • During dry periods, transpiration can contribute to the loss of moisture in the upper soil zone, which can have an effect on vegetation and food-crop fields. (usgs.gov)
  • leaves
  • The xylem vessels transport water and minerals from the root hairs to all the rest of plant i.e. to very tips of the leaves. (docbrown.info)
  • Phloem cells are living cells and the phloem tube tissues carry dissolved sugars (food) from the leaves to the rest of the plant, including the growing regions and the storage organs. (docbrown.info)
  • Since I wanted to measure the amount of water lost from the leaves, I took a plastic sandwich bag and wrapped it very tightly around the beaker, and around the stem of the plant. (amybrownscience.com)
  • The only way water is getting out of this beaker is through the leaves of this plant! (amybrownscience.com)
  • Hedrich, R. 2004-10-13 00:00:00 Inorganic and organic salts, amino acids, sugars, and phosphate esters (concentrations usually 25 mM) were fed via the transpiration stream through the petiole into detached leaves of Lepidium sativum and Solanum tuberosum. (deepdyve.com)
  • Young plant stems and leaves rely on their cells being turgid to keep them rigid. (weebly.com)
  • This picture shows water vapor transpired from plant leaves after a plastic bag has been tied around the stem for about an hour. (usgs.gov)
  • One way to visualize transpiration is to put a plastic bag around some plant leaves. (usgs.gov)
  • moisture
  • Independent variable: The amount of moisture residing in the air in the immediate vicinity of the plant. (studymode.com)
  • Studies have revealed that transpiration accounts for about 10 percent of the moisture in the atmosphere, with oceans, seas, and other bodies of water (lakes, rivers, streams) providing nearly 90 percent, and a tiny amount coming from sublimation (ice changing into water vapor without first becoming liquid). (usgs.gov)
  • arid
  • The information on transpiration is vital for sustaining fragile ecosystem in arid/semiarid environment, including the Horqin Sandy Land (HSL) located in northeast China. (mdpi.com)
  • Some plants which grow in arid regions, such as cacti and succulents, conserve precious water by transpiring less water than other plants. (usgs.gov)
  • crops
  • In Europe, greenhouse design and construction are governed by the Standard EN 13031-1:2001 where the following definition is given: "Greenhouse is structure used for the cultivation and/or protection of plants and crops that exploits the transmission of solar radiation under controlled conditions to improve the environment of growth, with dimensions that allow people to work inside. (hindawi.com)
  • conditions
  • A true control would be the absence of transpiration, but we decided to use a plant at normal room conditions as our control. (amybrownscience.com)
  • Mediterranean countries offer very favorable climatic conditions for growing plants in a protected environment: as a matter of fact, the high solar radiation allows the use of greenhouses with simple structures, covered with plastic film and without fixed installations for winter heating. (hindawi.com)
  • The greenhouse can be seen as a solar collector which exploits the radiation coming from the sun to create optimal conditions for plant growth and development. (hindawi.com)
  • Simulation
  • This is a nice animation / simulation to show some plant tropisms, including phototropism gravitropism (along with auxin. (merlot.org)
  • This is an eloquently simple and straightforward simulation to show the importance of minerals in plant nutrition. (merlot.org)
  • cells
  • Plant tissue composed of spongy, living, thin- walled randomly arranged cells with large vacuoles. (coursehero.com)
  • Higher temperatures cause the plant cells which control the openings (stoma) where water is released to the atmosphere to open, whereas colder temperatures cause the openings to close. (usgs.gov)
