CREATION BY EVOLUTION 



Algae. 



Nearly all grow in water, with spores unprotected. 



From water to land 

 Liverworts and Mosses. 



Have spores in a protecting spore case and grow on moist land. 

 Have no true roots but have root-like organs {rhizoids). 



From rhizoids to roots 



Club Mosses. 



Have roots and water-conducting tissue and grow on drier land. 

 Leaves small. Reproduce by spores. One spore case. Each spore 

 develops into a small sexual plant {prothallus). 



From small leaves to large leaves 



Ferns. 



Spores usually all of one size and germinate on moist ground. 

 No seeds. 



From spores to seeds 

 Cycads. 



Two sizes of spores, which grow to small sexual plants that 

 develop on the parent plants, thus producing seeds. Cycads have 

 swimming sperms, as do all the preceding forms. 



Conifers (cone-bearing plants). 



These and the flowering plants do not have swimming sperms. 

 Cycads and conifers have naked seeds — that is, they are gymno- 

 s perms. 



From cones to flowers 



Anthophyta (flowering plants). 



Seeds enclosed in a covering — the fruit. Some seeds have two 

 seed leaves {cotyledons), some only one, thus forming the follow- 

 ing groups: 



Dicotyledons. 



Two seed leaves; leaves netted veined; parts of the flower 

 in fives or fours. 



Monocotyledons. 



One seed leaf; leaves usually parallel veined; parts of the 

 flowers in threes. 



The above summary takes account of all the great groups 

 shown in the exhibit except the fungi, which form one of 

 the lower branches, just a little above the algae. The fungi 

 resemble the algae in essential characters, except that none of 

 them has the green coloring matter of plants, known as leaf-
