Morphological Relations. Bacteria, the lowest of all the 

 microorganisms known, are generally classed as plants. Their 

 relationship, however, is by no means clearly defined. Like 

 members of the vegetable kingdom .certain species have the 

 ability to use as food such simple elements as inorganic carbon 

 and nitrogen; on the other hand certain species show a resem- 

 blance to the animal kingdom in requiring complex organic food. 

 The non-motility of some, and the tendency to a thread-like 

 growth, suggests their relationship to plant life; the motility of 

 others and the fact that none possess chlorophyl, the green color- 

 ing of plants, suggest a kinship to the animal kingdom. It is best
