7. The fully formed chromosomes are then seen to be con¬ 
nected by delicate strands. About this time or a little before the

8. The chromosomes are taken on to a bipolar spindle and 
gradually pulled into the equatorial plane. 
9. There is an irregularity in the formation of the micro¬ 
spores. Frequently as high as eight are formed from one sporocyte.
