7. During the metakinesis stage the chromosomes uncoil and 
separate by a transverse division at the middle. 
8. The chromosomes of the second division appear to represent 
the daughter chromosomes of the first division. 
g. The division of the chromosomes in the second nuclear divi- 
sion is longitudinal. 
10. The nucleoli fragment and pass out into the cytoplasm during 
the first and second divisions and also during the germination of the 
microspore.
