796 APPENDIX 



Class Chlorophyceae — green algae, with definite nuclei and chloroplasts. 



Ex. Volvox, Spirogyra 

 Class Phaeophyceae. The brown algae, large seaweeds. 

 Class Rhodophyceae. The red algae, usually marine plants. 

 Class Bacillariaceae. Diatoms. 

 Subphylum Fungi. Thallophytes without chlorophyll, either parasites or 

 saprophytes 



Class Myxomycetes. Slime molds. The body is a blob of protoplasm con- 

 taining many nuclei, but not perfectly divided into cells. 

 Class Phycomycetes. Bread molds and leaf molds. 

 Class Ascomycetes. Yeasts, mildews and cheese molds. 



Ex. Penicillium. 

 Class Basidiomycetes. Mushrooms, rusts, smuts. 

 Phylum Bryophyta. Multicellular plants, with a marked alternation of sexual 

 and asexual generations (23,000 species). 

 Class Hepaticae. Liverworts. 

 Class Musci. Mosses. 

 Phylum Pteridophyta. Multicellular, terrestrial plants, with true roots, stems 

 and leaves, and with alternation of sexual and asexual generations. The 

 asexual generation is more prominent. 



Class Lycopodineae. Clubmosses, ground pines. 

 Class Equisetineae. Horsetails. 

 Class Filicineae. Ferns. 

 Phylum Spermatophyta. Multicellular plants with well-developed roots, stems 

 and leaves. The familiar dominant is the sporophyte or asexual plant. Trees, 

 shrubs, and seed plants. 



Subphylum Gymnospermae. Without flowers; the seeds are borne on the 

 surface of the cone scales. Order Coniferales. Evergreen trees and shrubs, 

 pines, firs, with needle-shaped leaves. 



Subphylum Angiospermae. Flowering plants with seeds enclosed in ovary. 

 Class Dicotyledoneae. Most flowering plants. Embryos with two seed 

 leaves or cotyledons. 



Order Rosales, rose, apple, strawberry, cherry and others. A 

 dozen and more orders containing great numbers of familiar 

 flowering plants. 

 Class Monocotyledonae. Leaves with parallel veins. Embryos with one 

 seed leaf. Grasses, lilies, and orchids. 



The Animal Kingdom 



Animals rarely have stiff cell walls and do not have chlorophyll. The excep- 

 tions are mainly border line organisms such as Euglenas that are brilliant green. 

 Phylum Protozoa. The simplest animals, one-celled, microscopic, some of them 



living in colonies. Many are free-living; others are parasitic. Ameba, Vorti- 



cella (colonial).
