PRACTICAL QUESTIONS 



1. What are flowers, and what is their purpose? 2. What is 

 meant by reproduction ? 3. Do all flowering plants reproduce by 

 seeds ? 4. Describe a pear blossom or any other blossom. 5. How 

 many parts are there to a pear blossom ? 6. Give the function or 

 use of each part. 7. Define self-pollination and cross-pollination. 

 8. How do plants secure cross-pollination? 9. In what ways are the 

 bumblebees and the blossoms of the red clover suited to each other? 

 10. Account for the small amount of seed in the first crop of red 

 clover. 11. Have you ever noticed any insects besides bees visiting 

 flowers? 12. Distinguish between a perfect and an imperfect flower. 



13. Describe the two kinds of flowers borne on the cornstalk. 



14. Will the grains of corn develop without pollen? 15. How do 

 you account for cobs only partly filled out with corn ? 



HOME EXERCISES 



1. Ascertain how each farm plant reproduces. Have you ever 

 seen flowers on potato plants? Examine a head of wheat shortly 

 after the flowers have appeared. Is the pollen carried from head to 

 head ? 



2. Collect all the different farm flowers that you can find, and de- 

 scribe those of the leading crops. Bring report along to school. 



SUGGESTIONS 



1. In learning the names of the parts of a flower care should be 

 taken not to select flowers for study that belong to the daisy family 

 or that are very small. Large, simple specimens should be selected. 



2. The flower selected should be pulled apart, and its parts care- 

 fully noted and described. 



3. An effort should be made to determine which flowers are 

 visited by insects and which are not. This work must be done in 

 the field. The kinds of flowers visited should be noted. It is 

 interesting to determine whether showy and fragrant flowers are 

 more frequently visited than other kinds. 



4. Bring to the schoolroom a few red clover blossoms. Count the 

 number of flowers in each head, and look for the nectar glands. An 

 interesting exercise would be to study the red clover blossoms in the 

 field for the kinds of insect visitors.
