What's the difference between apex and orthotropous?
Apex
Definition:

Orthotropous
Definition:
(a.) Having the axis of an ovule or seed straight from the hilum and chalaza to the orifice or the micropyle; atropous.
Example Sentences:

(3) It has been proposed that the orthotropic elastic constants of cancellous bone depend upon a tensorial measure of anisotropy called fabric as well as the tissue's structural density.
(4) The thin and thick lamellae are modeled as orthotropic composite layers made up of thin rectangular apatite platelets within a collagen matrix, and classical orthotropic elasticity theory is used to calculate the Young's modulus of the lamellae.
(5) The error in the prediction of the orientation of the principal axes of stress in bone tissue is determined in the case when the tissue is modeled as elastically isotropic rather than as orthotropic, the probable symmetry of bone tissue.
