E N D
Structures • Macronucleus deals with everyday functions like metabolism. • Micronucleus deals with all of the germ line DNA (Genes which are traded during sexual reproduction).
Structures • Trichocyst are the defense of the paramecium, a harpoon like structure that releases a toxin to kill or paralyze other microorganisms
Paramecium use cilia to move around Cilia are like little oars used to move forward, backwards, and side to side Locomotion Cilia
Conjugation • During conjugation, two paramecium attach to each other, losing some of their cilia in the process. • Conjugation is used to trade genetic information between two paramecium.

Review Questions • What part of the paramecium is used to defend itself from predators? • Which Nucleus deals with every day functions, such as metabolism? • Which nucleus deals with the germ line DNA? • What type of locomotion do paramecium use to move? • In the beginning of conjugation, what is lost on the paramecium? • What is conjugation used for?
Answers • Trichocyst • Macronucleus • Micronucleus • Cilia • Cilia on the area that attaches with another paramecium • Used as a way to add to the genetic make-up of paramecium
