In this way, growths will form in the tanks; they will be colored (according to the metal cation) and may look like plant-like structures. The usual upward direction of growth depends on the density of the fluid inside the semi-permeable membrane of the "plant" being lower than that of the surrounding waterglass solution.

Specular reflection, or regular reflection, is the mirror-like reflection of waves, such as light, from a surface. [ 1 ] The law of reflection states that a reflected ray of light emerges from the reflecting surface at the same angle to the surface normal as the incident ray, but on the opposing side of the surface normal in the plane formed by ...
Mesocosm experiments also tend to include replication of different treatment levels. Manipulating something can give an idea as to what to expect if something were to occur in that ecosystem or environment. [2] For indoor mesocosms, growth chambers grant greater control over the experiment. [2]
