| wall-eyed | Having an eye of a very light gray or whitish colour. Shakespeare, in using wall-eyed as a term of reproach (as "wall-eyed rage," a "wall-eyed wretch"), alludes probably to the idea of unnatural or distorted vision. See the Note under Wall-eye. It is an eye which is utterly and incurably perverted, an eye that knows no pity. Origin: Icel. Valdeygthr, or vagleygr; fr. Vagl a beam, a beam in the eye (akin to Sw. Vagel a roost, a perch, a sty in the eye) + eygr having eyes (from auga eye). See Eye. Source: Websters Dictionary (01 Mar 1998) |

| primary cell wall | <plant biology> A plant cell wall that is still able to expand, permitting cell growth. Growth is normally prevented when a secondary wall has formed. Primary cell walls contain more pectin than secondary walls and no lignin is present until a secondary wall has formed on top of them. (06 Mar 1998) |
| helicoidal cell wall | Type of plant cell wall in which each wall layer contains parallel microfibrils, but in which the orientation of the microfibrils changes by a fixed angle from one layer to the next. Gives a characteristic herringbone pattern in transmission electron microscopy. A similar architecture of fibrillar material is seen in some insect exoskeletons. (18 Nov 1997) |
| secondary wall | <plant biology> The part of the plant cell wall which is laid down on top of the primary wall after the wall has ceased to increase in surface area. Only occurs in certain cell types, for example tracheids, vessel elements and sclerenchyma. Differs from the primary wall both in composition and structure and is often diagnostic for a particular cell type. (18 Nov 1997) |
| hollow wall | A condition of the hoof wall in the toe region of horses, characterised by loss of substance and change in character of the horn, most often as a sequela of mild chronic laminitis. Synonym: dystrophia ungulae, hollow wall. (05 Mar 2000) |
