CHAP. XXVII FLESHY FRUITS 113 



1. The fleshy pericarp enclosing 



2. Four spaces (the cells) > in each of which are 



3. Several seeds. 



4. Make a sketch of one of the cut surfaces and label. 



VI. Gooseberries, Currants, Bananas, Tomatoes, and 

 Grapes are also good typical berries (in the last two the 

 pericarp consists of the changed ovary wall simply, while 

 in the others, as in the Cranberry, the pericarp is the ovary 

 wall plus the adherent calyx-tube), but the seeds appear 

 buried in fleshy material. There are also several kinds of 

 fruits that are really berries and yet have certain peculiar- 

 ities. Such are i\\epome, the hespcridium, and \h& pepo. 



VII. The Pome. Examine a ripe Apple and notice : 



1. Its general size, shape, color, and odor. UJ^-N 



2. The stalk at one end. 



3. The five} sepal-lobes in the depression at the other. 



4. Make a sketch and label. 



VIII. Cut the Apple across at the middle and, examining 

 the cut surface carefully, notice : 



1. The outline of the section. 



2. The five openings (cells) each with a papery wall. (This 



can be demonstrated by prying it away from the flesh. 

 It represents the wall of the ovary and forms with 

 No. 3 the "core" of the apple.) 



3. The fleshy portion outside of No. 2, bounded by a 



greenish lineJrom 



4. The outer flesh bounded upon the outside by : 



5. The outside skin. 



6. Make a sketch of the section and label the parts. 



7. (Notice the tough seed-coats.)
