Fig. 6-27 Photograph of cells fixed in 1 part formaUn plus 

 4 parts water and stained with Lugol's solution. The chromosomes 

 stain dark brown suggesting that they are covered with carbo- 

 hydrate. This precedes the accumulation of volutin on the chromo- 

 somes and suggests that the energy for the transformation of 

 orthophosphate to metaphosphate is obtained from the localized 

 carbohydrate .
