CHAPTER 19 – PROTISTS

 

Characteristics of Protists

 

 

 

 

 

 

 

Movement of Protists is achieved by:

 1.          Flagellum -

 

 

2.          Cilia

 

 

3.          Pseudopods

 

 

 

  

 

 

 

 

 

Protists can sense & respond to environment

 Euglena have an ___________________ that detects light. They are ____________________ (and ___________________), and swim toward light

 

Paramecium avoid light -> seek __________ places where food (__________________________) may be found.
