FIG. 132. Drying copra, the fleshy portion (endosperm) of the coconut seed. The 

 coconuts are split and set in the sun, and the meats, after they shrink and become 

 loose, are removed from the shells and placed on mats to dry. Copra is the source of 

 coconut oil. 



PROBLEMS 



1. Why does a corn plant growing alone produce imperfect ears? 



2. When cucumbers are grown in commercial greenhouses, how is pollination 

 accomplished ? 



3. Why are large, heavy seeds of agricultural plants more desirable for plant- 

 ing than small, light seeds? 



4. What common market "vegetables" are included in the botanical term 

 "fruit"?
