The Embryo - 



The embryo be.p;ins f^rowth comparatively late, so 

 that the endosperm has already acquired some size be-

 The egff-cell after fertilization becomes sli-h+ly im- 

 bedded in the tissue of the tapetal strand, and en-

 this co>itinued cross division the suspensor may have 

 five or six cells cut off (^iF>- 35). The first divis-
