Cell-Bundles 
Cellulose 
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; ~ 
Divis‘ion, 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 ; ~ Family, 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 ; 
~ Fv'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; ~ Nw'‘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; ~ 
~ 
47 
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 .Couroupita, 
Aubl. ; (2) ta form of perithecium in 
Fungi (Lindley) ; cellif‘erous (fero, 
I bear), bearing or producing cells. 
Cel'lul (celluda, a cell), Blair’s term 
for anther; cel’lular, cellula’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 =SroripEsM ; 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- 
liferous, (fero, 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 SPoRIDESM. 
Cell’ulose (cellula, 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 ; Cell’uloses, 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
