THE PLANT CELL. 



Fig. 105. — 1. An arohegonium at the apex of the embryo-sao of Pimm, 

 containing an oosphere which has just received a generative nucleus 

 from the microspore (small nucleus just above the larger one of the 

 oosphere). 



2. The first two divisions at the lower pole of the oospore, subsequent 

 to fertilisation. 



3. Shows the appearance at the end of the third division. The 

 lowest cells are the embryonal cells ; the lowest but one (6) are the 

 cells from which the suspensors are produced.
