What's the difference between micropyle and orthotropous?
Micropyle
Definition:
(n.) An opening in the membranes surrounding the ovum, by which nutrition is assisted and the entrance of the spermatozoa permitted.
(n.) An opening in the outer coat of a seed, through which the fecundating pollen enters the ovule.
Example Sentences:

(2) This stain permits pollen tubes to be traced even up to their entry into the micropyle.
(3) The outer layer formed densely accumulated protrusions, whilst the inner layer was smooth and formed a collar structure around the micropyle.

(11) are ellipsoidal, 27.3 x 23.6 (22-30 x 20-27) microns; a polar body is present, but no oocyst residuum or micropyle occurs.
(12) The structure of oocysts is described; a peculiar bumpy surface and a calyx-like thickening around the micropyle are illustrated by scanning electron microscopy.
(13) The oocyst wall is smooth, single-layered, with no micropyle.
(14) This indicates a new function for these cells though previously to contribute mainly in the formation of the micropyle.
(15) Neither micropyle, polar granules, nor oocyst residuum were present.
(16) A rapid and steady growth of pollen tubes, their accumulation near the micropyle and penetration in it are observed in self-fertile plants.
(17) After microinjection into fertilized, nonactivated Atlantic salmon eggs via the micropyle, transgenic Atlantic salmon were generated.
(18) are spheroid or subspheroid, 24.6 x 23.5 (21-27 x 20-25) microns, with a shape index of 1.05 (1.0-1.09) but with no micropyle, oocyst residuum, or polar granules.
(19) A micropyle and micropylar cap were observed, but a polar granule and oocyst residuum were absent.
(20) The oocyst wall is a single, colorless layer about 0.6-1.0 microns thick with no striations or micropyle.
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:
(1) Modifications are made so that the Hooke's law constitutive equations of stress may be applied to the inhomogeneous, non-lineary elastic and orthotropic thin (membrane) aortic valve leaflets.
(2) In this study the orthotropic elastic moduli, structural density, and fabric components were measured for 11 cancellous bone specimens from five bovine femora and for 75 specimens from three human proximal tibiae and fitted to these relationships using a least squares analysis.
(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.
(6) Electrical propagation relies on an orthotropic conductivity tensor defined with respect to the local material axes.
(7) The artery is considered orthotropic and loaded with an incremental pressure of 40 mmHg.
(8) The thermodynamic restrictions on the elastic coefficients of linear orthotropic elasticity and linear transversely isotropy elasticity are recorded and it is shown that previously reported data for the elastic orthotropic constants of bone satisfy these thermodynamic restrictions.
(9) In this paper, these two methods will be evaluated using an exact theory for wave propagation in orthotropic plates.
(10) Results from orthotropic and strabismic adults and from children are evaluated to establish reference values.
(11) Orthotropic behavior of the bone structure was confirmed.
(12) When the nine orthotropic elastic constants were forced to approximate the five transverse isotropic elastic constants, errors of over 60 percent were introduced.
(13) A three dimensional model has been developed by adopting an orthotropic material law for cortical bone and an isotropic law for the fracture gap zone.
(14) The annulus fibrosus is modelled either as nonhomogeneous fibre reinforced composite or alternatively as homogeneous orthotropic with transverse isotropy.
(15) Earlier work gave the three orthotropic Young's moduli of the cortical one of the canine femur as 12.8 GPa, 15.6 GPa and 20.1 GPa.

(19) Simulation of glottal volume flow and vocal fold tissue movement was accomplished by numerical solution of a time-dependent boundary value problem, in which nonuniform, orthotropic, linear, incompressible vocal fold tissue media were surrounded by irregularly shaped boundaries, which were either fixed or subject to aerodynamic stresses.
(20) The plate and bone contact as well as the fracture site contact were modelled by using orthotropic elements with custom-fit moduli so that only the normal stress to the interface was significant.
