Notice that the region lying between the plumule and primary root joins the embryonic plant- 

 let with the rest of the seed. It is by way of this connection that the embryonic plantlet, 

 when germinating, secures the food stored for its use in the endosperm. 



Make a drawing of the kernel as it appears after shaving away the surface of the "germ" 

 side. Indicate the parts of the drawing which represent hull, endosperm, "germ" and embry- 

 onic plantlet — dimensions of the drawing to be five times that of the specimen. Shade that 

 portion of the kernel showing vitreous starch in contrast with the soft or white starch. 



8. Select a kernel which has a stem sprout about one-half inch in length. Make a neai 

 drawing of the specimen. Indicate on the drawing the parts which represent plumule and pri- 

 mary root. 



9. Select good specimens of corn which have been growing from 8 to 10 days. The speci- 

 mens should show at least two green leaves, roots, and kernel attached. Make a careful out- 

 line drawing about natural size.
