10 STUDIES OF ANIMAL LIFE. 



1. How many are there ? (Do not confuse them with 



food vacuoles.) 



2. Where are they situated ? 



3. Does it take longer for them to disappear than to 



reappear ? 

 What becomes of them when they disappear ? 



F. The Animal as a Single Cell. (Dem.)i 



1. Is a definite cell wall discernible ? 



2. Can you distinguish nucleus from cytoplasm ? 



G. Reproduction. (Dem.)i 



1. Do you find any animals pinching into two parts, 



dumbbell fashion? This is "multiplication by 

 division. " 



2. Do you find any double ones, i.e. two Paramcecia 



fused together lengthwise side by side ? This is 

 "conjugation." 



H. Drawings. 



1. Draw an accurate outline (4 cm.)^ and include in it 



only the food-balls and gullet. 



2. Draw another similar outline and include in it only 



the two kinds of vacuoles. 



3. Draw the animal as a cell. (F.) 



4. Draw anything which you found under G. 



I. Suggestive Questions. 



1. Why are protozoa so universally distributed? 



2. Do Paramcecia show any signs of intelligence ? 



3. Have they any means of self-defence ? 



4. Are they sensitive to light ?
