THE ORGANIC CELL 
plants, in which the nucleus lies near the base of the hair ; 
the discrepancy, however, is only apparent, as it has been 
definitely shown that in these cases the growth is basal and not 
apical. 
From the above it will at once be conceded that the nucleus 
initiates morphological synthesis, the result of its presence being 
the orderly and natural development of the structure. 
Position of Nuclei in Growing Root Hairs of the Pea. 
(Haberlandt.) 
According to Korschelt ‘ there is a definite correlation, 
on the one hand, between the position of the nucleus and the 
source of food- supply, on the other hand between the size of 
the nucleus and the extent of its surface and the elaboration 
of material by the cell.’ In proof of the latter, we have the 
enormous nuclei of secreting cells, these nuclei being very 
branched, so that there is a maximum of their surface brought 
into action. This kind of nucleus, with its associated function, 
is well exemplified in the case of the Annelids, in some forms
