III. Mitochondria. 



1. The mitochondria are represented in the youngest oocytes 

 by several irregular-shaped granules. 



2. As the oocyte grows these granules become spread out in 

 the cell. 



3. They remain comparatively inert until the process of yolk 

 formation is well 'advanced ; they then begin to divide, to form 

 typical granular mitocliondria, which become fairly regularly dis- 

 tributed in the cytoplasm. 



4. Mitochondria in Patella take no direct part in yolk forma- 

 tion.
