THE RELATIONSHIP OF BACTERIA IIQ 



6. Some species of bacteria possess the power of breaking 

 up carbon dioxide (CO*) into carbon (C) and oxygen (O) 

 without the aid of chlorophyll and sunlight, which are used 

 by higher plants. In some cases the carbon and oxygen are 

 derived from carbonates. They differ from all plants and 

 animals in this respect. 



7. Certain bacteria of the soil take up free nitrogen of the 

 air, and in this they resemble some few species of fungi and 

 differ from all animals. 



8. A large number of species of bacteria possess organs of 

 locomotion called flagella or cilia, and in this respect they 

 resemble certain animal forms among the protozoa. 



9. Bacterial cells possess no definite nucleus as most animal 

 and plant cells do. The cell protoplasm is undifferentiated 

 and the chromatic material distributed throughout all the 

 parts of the cell. 



10. Bacterial cells, like all higher plants, do not produce 

 any nitrogen-containing excretions. 



Relationship to Plants. Vegetation on the earth may be 

 divided into four divisions, which are quite distinct. 



1. Thallophyta Algae, fungi, etc. 



2. Bryophyta Mosses. 



3. Pteridophyta Ferns. 



4. Spermatophyta Seed plants. 



The first three divisions compose the Cryptogamia, or 

 non-flowering plants. 

 The microorganisms known as bacteria belong to the
