3. How would you proceed to measure the rate of respiration of green leaves? 



Evaluate the method chosen for sources of error. 



4. What gas is usually lost from green plants during the day? At night? 



Answer the same questions for a non-green plant. Under what conditions 

 is there no gas exchange between a green plant and its environment? 



5. Would the complete elimination of all animal life from the face of the earth 



alter the relative proportions of CO2 and Oi: in the atmosphere? Explain. 



6. How valid is the belief that it is harmful to keep flowers in a sickroom at 



night? 



7. Compare the effects of temperature upon the processes of respiration and 



photosynthesis and offer possible explanations for any differences. 



8. In a certain experiment corn seedlings which had developed for some time 



in a dark room were measured for the daily variations in rate of respira- 

 tion. It was found that the rate per hour was practically constant in 

 spite of the fact that marked variations in temperature occurred during 

 the day. Explain. 



9. What are some of the ways in which the respiration of living plant tissue 



might alter the environmental conditions to which it was subject? 



10. WTiat daily variations would you expect to find in the rate of respiration 



of an attached green leaf under "standard day" conditions? 



11. Why do starchy seeds decrease proportionately more in dry weight during 



germination than oily seeds?
