  2. Hydroponics - Wikipedia

    en.wikipedia.org/wiki/Hydroponics

    He found that plants in less-pure water sources grew better than plants in distilled water. By 1842, a list of nine elements believed to be essential for plant growth had been compiled, and the discoveries of German botanists Julius von Sachs and Wilhelm Knop, in the years 1859–1875, resulted in a development of the technique of soilless ...

    en.wikipedia.org/wiki/Aquaponics

    A Deep Water Culture hydroponics system where plant grow directly into the effluent rich water without a soil medium. Plants can be spaced closer together because the roots do not need to expand outwards to support the weight of the plant.

    Helophytes are plants that grow partly submerged in marshes and regrow from buds below the water surface. [24] Fringing stands of tall vegetation by water basins and rivers may include helophytes. Examples include stands of Equisetum fluviatile , Glyceria maxima , Hippuris vulgaris , Sagittaria , Carex , Schoenoplectus , Sparganium , Acorus ...

    en.wikipedia.org/wiki/Plant_nutrition

    Hydroponics is a method for growing plants in a water-nutrient solution without using nutrient-rich soil or substrates. Researchers and home gardeners can grow their plants in a controlled environment. The most common artificial nutrient solution is the Hoagland solution, developed by D. R. Hoagland and W. C. Snyder in 1933.

    Now the plant can absorb more light. When the sun dries the plants, they turn white. Thanks to this special survival trick, plants without roots can absorb fog droplets as well as rainwater and thus cover their water needs. [18] More than one-third of a tropical forest's vascular plants are epiphytes which species of Tillandsia are part of.

  7. Bryophyte - Wikipedia

    en.wikipedia.org/wiki/Bryophyte

    Bryophytes exist in a wide variety of habitats. They can be found growing in a range of temperatures (cold arctics and in hot deserts), elevations (sea-level to alpine), and moisture (dry deserts to wet rain forests). Bryophytes can grow where vascularized plants cannot because they do not depend on roots for uptake of nutrients from soil ...

  8. Nymphaeaceae - Wikipedia

    With their knowledge of the wetland biosphere, they transformed artificial reservoirs into wetland biospheres. One way that they tested whether the water systems were working properly was if the Nymphaeaceae were thriving. Water lilies became a visual sign of water cleanliness, so the Maya elite began to associate themselves with the flowers. [34]

  9. Xerophyte - Wikipedia

    en.wikipedia.org/wiki/Xerophyte

    Plants absorb water from the soil, which then evaporates from their shoots and leaves; this process is known as transpiration. If placed in a dry environment, a typical mesophytic plant would evaporate water faster than the rate of water uptake from the soil, leading to wilting and even death.
