Cysts and Trophozoites

• Label the picture.

  A) Nuclei

  B) Median (parabasal) bodies

  C) Flagella

  D) Axostyle

  E) Axonemes

  
• Median or parabasal bodies: part of a flagellates trophozoite that functions for metabolism, energy, and support.
• Flagella: aids in the motility of flagellates
• Axostyle: provides structural support
• Label the following:

  A) Anterior flagella

  B) Conical cytostome

  C) nucleus

  D) axostyle

  E) trailing flagellum

  F) costa

  G) undulating membrane (full body length)

  
• Label the following:

  A) cyst wall

  B) nuclei

  C) cytoplasma beginning to retract from cyst wall.

  
• conical cytostome: mouth
• Costa: connects the undulating membrane to the trophozoite body
• undulating membrane: movement of flagellates' trophozoites
