Outermost layer of root-cap. c. Wall marking the inner limit of the outer cortex.
The outermost is the caiyptrogen, which gives rise to the root-cap, and in Dicotyledons to the piliferous layer as well.
The outermost, newly formed layer is composed of a more homogeneous, denser substance than the inner one, and can be distinguished in all starch-grains that are in process of development.
St.) is attached to the upper wall of the drum cavity; the outermost (e.
The third or outermost chamber, the proctodaeum, is closed externally by the sphincter ani; the orifice is quite circular.
In the Oscines or Polymyodi of Muller the number was either nine or ten - and if the latter the outermost of them was generally very small.
In two of the other groups of which Professor Cabanis, especially treated - groups which had been hitherto more or less confounded with the Oscines - the number of primaries was invariably ten, and the outermost of them was comparatively large.
The extreme discrepancy is that between the waves which travel through the outermost parts of the object-glass at L and L'; so that if we adopt the above standard of resolution, the question is where must P be situated in order that the relative retardation of the rays PL and PL' may on their arrival at B amount to a wave-length (X).
In the Phylactolaemata the outermost layer of the bodywall is a flexible, uncalcified cuticle or "ectocyst," beneath which follow in succession the ectoderm, the muscular layers and the coelomic epithelium.
The decans are ranged on the outermost of its five concentric zones; the planets and the Greek zodiac in duplicate occupy the next three; while the inner circle is unaccountably reserved for the Chinese cyclical animals.
It is a strikingly marked characteristic of the northern edge of the Tibetan plateau that its outermost border-range (e.g.
The Astin-tagh, although it occupies a similar position to the twin ranges of the Western Kuen-lun, in that it forms the outermost escarpment or border-ridge on the north of the Tibetan plateau,would appear in the opinion of the most competent judges (e.g.
The totality of being may thus be conceived as a series of concentric circles, fading away towards the verge of non-existence, the force of the original Being in the outermost circle being a vanishing quantity.
It is the outermost garment worn by bishops and priests at the celebration of the Mass, forming with the alb the most essential part of the eucharistic vestments.
More important is San Francisco Bay, situated about midway on the Pacific coast of the United States, the result of a moderate depression whereby a transverse valley, formerly followed by Sacramento river through the outermost of the Coast ranges, has been converted into a narrow straitthe Golden Gate and a wider intermont longitudinal valley has been flooded, forming the expansion of the inner bay.
Some of the outermost tubules of the ep06phoron are sometimes distended to form hydatids.
The outermost hyphae may even put forth thinner hyphae, radiating into the soil like root-hairs, and the convergent tips may be closely appressed and so divided by septa as to resemble the root-apex of a higher plant (Armillaria mellea).
The outermost of the now solid metal; (2) the inner layers, i.e.
Here the outermost circle represents a section of that portion of the axis bearing the lowest leaf, the innermost represents the highest.
Under favourable conditions four concentric rings may be seen round the shadow of the observer's head, the outermost, which seldom appears, having an angular radius of 40°.
- In the skull there is a sagittal crest; the tympanic bulla is filled with cancellous tissue; the condyle of the lower jaw is rounded; and the premaxillae, or anterior bones of the upper jaw, have the full number of incisor teeth in the young state, the outermost of these being persistent through life as an isolated tooth.
Of these the first upper premolar is a simple tooth placed close behind the premaxilla and separated by a long gap from the two other teeth of the same series; while the lower incisors, of which the outermost is the largest, are directed partially forwards.
In the skull the socket of the eye is surrounded by bone; while the dentition begins to approximate to the camel type - notably by the circumstance that the lower canine is either separated by a gap from the outermost incisors, or that its crown assumes a backwardly curved shape.
The latter lay their eggs in one and the same nest, a shallow pit scraped out by their feet, with the earth heaped around to form a kind of wall against which the outermost circle of eggs rest.
Teodo, on the outermost gulf, is a small naval port.
The outermost layer of endosperm, the aleuron-layer, consists of regular cells filled with small proteid granules; the rest is made up of large polygonal cells containing numerous starch-grains in a matrix of proteid which may be continuous (horny endosperm) or granular (mealy endosperm).
The outermost crescent canal is called the Singel Gracht (girdle canal), and marks the boundary of the city at the end of the 17th century.
