  2. Diffusion - Wikipedia

    en.wikipedia.org/wiki/Diffusion

    Some particles are dissolved in a glass of water. At first, the particles are all near one top corner of the glass. If the particles randomly move around ("diffuse") in the water, they eventually become distributed randomly and uniformly from an area of high concentration to an area of low, and organized (diffusion continues, but with no net flux).

  3. Diffusion (acoustics) - Wikipedia

    en.wikipedia.org/wiki/Diffusion_(acoustics)

    Diffusion, in architectural acoustics, is the spreading of sound energy evenly in a given environment. A perfectly diffusive sound space is one in which the reverberation time is the same at any listening position. Most interior spaces are non-diffusive; the reverberation time is considerably different around the room.

  4. Vivarium - Wikipedia

    en.wikipedia.org/wiki/Vivarium

    A greenhouse is an enclosure for plants with a glazed roof and wall(s) that allow the plants to make use of natural sunlight. A conservatory is a room of a house or of another building, with a glazed roof and wall(s) that combines growing space for plants with a sitting room or dining area for people. Some conservatories also house animals such ...

  5. Plasmodesma - Wikipedia

    en.wikipedia.org/wiki/Plasmodesma

    Neighbouring plant cells are therefore separated by a pair of cell walls and the intervening middle lamella, forming an extracellular domain known as the apoplast. Although cell walls are permeable to small soluble proteins and other solutes, plasmodesmata enable direct, regulated, symplastic transport of substances between cells. There are two ...

  6. Green wall - Wikipedia

    en.wikipedia.org/wiki/Green_wall

    Green wall at the Simon Fraser University, Burnaby, British Columbia, Canada.. A green wall is a vertical built structure intentionally covered by vegetation. [1] Green walls include a vertically applied growth medium such as soil, substitute substrate, or hydroculture felt; as well as an integrated hydration and fertigation delivery system. [1]

  7. Transpiration - Wikipedia

    Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata 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 .

  8. Diffuse reflection - Wikipedia

    en.wikipedia.org/wiki/Diffuse_reflection

    Diffusion affects the color of objects in a substantial manner because it determines the average path of light in the material, and hence to which extent the various wavelengths are absorbed. [6] Red ink looks black when it stays in its bottle. Its vivid color is only perceived when it is placed on a scattering material (e.g. paper).

  9. Gas exchange - Wikipedia

    en.wikipedia.org/wiki/Gas_exchange

    Gas exchange is the physical process by which gases move passively by diffusion across a surface. For example, this surface might be the air/water interface of a water body, the surface of a gas bubble in a liquid, a gas-permeable membrane, or a biological membrane that forms the boundary between an organism and its extracellular environment.
