Cell-Bundles 



Metacelluloses 



containing the ovules or seeds ; <~ 

 Bun'dles, a band or bundle of 

 similar cells, as the bast fibre in 

 dicotyledons ; ~ Con'tents, of two 

 kinds, living or protoplasmic, and 

 non - living, such as starch, fats, 

 proteids, crystals, cell-sap, and 

 the substances dissolved in it ; <~ 

 Division, in free cell - division, 

 several daughter- cells are formed 

 in the cavity of the mother-cell ; 

 in ordinary cell division, as a 

 rule only two daughter- cells are 

 formed, usually followed by a 

 subsequent further division of 

 each ; <~ Fam'ily, a group of cells of 

 common origin, a colony or coeno- 

 bium ; ~ Fi'bres, the achromatic 

 filaments which form the nuclear 

 spindle in nuclear-division ; <~ 

 Forma'tion, the construction of a 

 new cell by reorganisation of the 

 protoplasmic energid, with or 

 without division of the cytoplasm ; 

 ~ Fu'sions, cells united by absorp- 

 tion or perforation of transverse 

 walls as Sieve- vessels ; ~ Groups, 

 associations of similar cells, as the 

 sclerenchyma in the pulp of the 

 pear, or in cork ; ~ Mas'ses, when 

 cells are united in all directions 

 of space, not having necessarily 

 any definite form ; ~ Multiplica'- 

 tion takes place by the forma- 

 tion of two or more protoplasmic 

 bodies out of one ; ~ Nu'cleus, 

 an organised structure within the 

 cell, the active agent in division, 

 usually spherical in form, and 

 of higher refractive power than 

 the rest of the cell-contents ; ~ 

 Plate, formed by the thickening of 

 threads of kinoplasm, marking out 

 the future septa : ~ Rows, have the 

 cells in contact by their ends, thus 

 making a filament ; <~ Sap, a 

 watery solution of various sub- 

 stances, salts, sugars, alkaloids, 

 and the like ; ~ Tissue, dis- 

 tinguished from vascular tissue by 

 being made up of cells only ; -~ 

 Sur'faces, where the cells form a 

 single layer, as in some Algae ; <~ 



Wall, a closed membrane, formed of 

 cellulose, and a small proportion of 

 mineral substances, originated by 

 the layer of protoplasm which lines 

 it, frequently thickened by second- 

 ary deposits. Primord'ial ~ , a cell 

 previous to the creation of a cell- 

 wall. 



Cel'la(Lat., storeroom), (1) Scopoli's 

 name for the fruit of Conroupita, 

 Aubl. ; (2) J a form of perithecium in 

 Fungi (Lindley) ; cellif'erous (fe.ro, 

 I bear), bearing or producing cells. 



Cel'lul (cell via, a cell), Blair's term 

 for anther ; cellular, celhda'ris, 

 consisting of cells, spongy : <~ Bark, 

 <~ En'velope, the middle layer of 

 the bark, mesophloeum ; ~ Plants, 

 plants which do not possess vas- 

 cular tissue ; non-vascular Crypto- 

 gams ; <~ Spore = SPOKIDESM ; Cellu- 

 la'res ; (1) plants which are built 

 up of cells only, as those last men- 

 tioned ; (2) recently the term has 

 been applied to all plants built up 

 of cells, in opposition to non- 

 cellular or unicellular ; Cell'ule, 

 Cell'ula, diminutive of cell ; cellu- 

 lif erous, (fe.ro, I bear), bearing or 

 producing cellules ; Cell'ulin, Pring- 

 sheim's term for a modification of 

 cellulose ; ~ Grains, bodies found 

 in vegetative hyphae ; Cellulo'sae, 

 Corda's name for SPOKIDESM, 



Cell'ulose (ceUula, a cell), (1) a 

 carbohydrate, the chief organic 

 base of the cell-wall ; (2) Dia- 

 tom valves composed of cellules 

 are termed cellulose, a synonym 

 of CELLULAR ; CelTuloses, a generic 

 term for the carbohydrate group 

 above mentioned ; divided by 

 chemists into sub-groups, as, Adi- 

 pocell'uloses (adeps, adipis, fat), 

 consisting of cuticular tissues of 

 leaves and fruits and of cork ; 

 Hemicell'uloses, all carbohydrates 

 in the cell-wall which are not 

 coloured blue by chlor-zinc-iodide, 

 such as reserve-cellulose, etc. ; Lig- 

 nocell'uloses, lignin combined with 

 cellulose, as in Jute fibre ; Meta- 

 cell'uloses, found in Fungi and
