1. How are AmcEbfe cultivated in the laboratory?

tion obtained ? 



3. How are they prepared for your examination? 



B. Shape and Movements. 



Find an Amceba in your preparation and watch it 

 carefully for some time. 



1. Make a series of outline sketches at intervals of 



, one minute to show the changes in shape which 

 this Amoeba undergoes. 



2. Can you describe the shape of the Amoeba? 



3. Does the Amoeba change its position? If so, make 



sketches to show its shape at successive inter- 

 vals. 

 The temporary projections which the Amoeba puts 

 out in its movements are called pseudopodia. Can 

 you apply the term " locomotion " to any of the 

 movements of the Amoeba?
