In anisotropic bodies (crystals), with which the theory of light is largely concerned, the problem is more complicated.
We ascend, in the one case as in the other, from the simplicities of the isotropic to the complexities of the anisotropic; and the laws of these isotropic and anisotropicresponses are the same in both.
A tabular statement of contractile response of various radial, anisotropic and pulvinated organs will show a continuity in the contractile reaction; the difference exhibited is a question of degree and not of kind.
From the responses of organs rendered anisotropic by the differential action of the environment we pass to others which show certain amount of anatomical and physiological differentiation between their upper and lower sides.
Thick lines represent the more excitable side of an anisotropic or dorsiventral organ.
The only condition requisite for the exhibition of response is the differential excitability of an anisotropic organ.
In fact such anisotropic stem of Mimosa acts somewhat like the pulvinus of the same plant.
Thermonastic movements are induced by the differential physiological effect of variation of temperature on the two halves of an anisotropic organ.
Curvature induced by diffused stimulus on a dorsiventral or anisotropic organ (with differential excitabilities of the two halves) is termed nastic.
The pulvinus of the leaf was stimulated by a horizontal beam of light thrown in a lateral direction; the areas contiguous to line of junction of the upper and lower halves of the anisotropic organ thus underwent differential excitation.
In the former the movement is autonomous and determined by the differential growth-activity of the two sides of an anisotropic organ.
Whether variation of temperature induces in anisotropic organs only one type of response, or two types, positive and negative.
The intermediate link is supplied by organs originally radial, but subsequently rendered anisotropic by the unilateral action of stimulus of the environment.
This view was no doubt largely suggested by the fact that the anisotropic liquids were turbid, whereas the "solid" crystals were clear.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "anisotropic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
