UNIT 6 Protists Focus on: Phyla of Protists How Protists are classified Amoeba, Paramecium, Euglena

Unicellular Section 6-1: Characteristics of Protists Protista Protists are members of the kingdom____________ Protists are ___________________ Protists reproduce by _______ _______ In this process of reproduction, the protozoan _______________________ ________________________________ Protista Unicellular binary fission splits into two new organisms by sharing traits. Protozoans may also reproduce by conjugation. In this process__________ __________________________________ ___________________________________ two protists join and exchange trait material

Move Section 6-1: Characteristics of Protists treat our C. Protists, like bacteria, can cause disease and sickness. Since protozoans are water-borne organisms, we must ____________ _________________________________ treat our water supply before drinking. Protozoans are classified by the way they: ______________ Move

Sarcodines Amoeba Ciliates Paramecium Protists Flagellates Euglena There are four groups of Protists: Sarcodines Amoeba Ciliates Paramecium Protists Flagellates Euglena Sporozoans Slime mold

used to surround food/prey. Section 6-2: The Amoeba I. Sarcodines – The Amoeba: A. Sarcodines move by means of _______________, A Pseudopod __________________________ _______________________________________ II. The Amoeba: Structures & Functions A. The Amoeba has the following organelles: 1) Food Vacuole: _______________________ 2) Contractile Vacuole ___________________ ___________________________________ 3) Nucleus: ___________________________ 4) Pseudopod: _________________________ 5) Cell Membrane:______________________ pseudopods is a false foot, that is used to surround food/prey. stores food releases excess water from inside Amoeba Controls all functions “false foot” for moving outer layer of Amoeba

Section 6-3: The Paramecium I. Ciliates – The Paramecium: A. Ciliates move by means of _______________, which are ________________________________ _______________________________________ II. The Paramecium: Structures & Functions 1) Pellicle: _____________________________ 2) Oral Groove: _________________________ 3) Gullet _______________________________ 4) Anal Pore: ___________________________ 5) Nucleus: ____________________________ 6) Contractile Vacuole:____________________ 7) Food Vacuole: _______________________ 8) Cilia: ______________________________ Cilia tiny hair-like structures that act like oars in water outer layer of Paramecium opening for food intake passes food into the vacuole removes wastes controls all functions releases water stores food tiny hair-like structures

a tail-like structure that propels the Euglena in water autotrophic Section 6-4: The Euglena Flagellates – The Euglena: A. All flagellates move by means of _____________, which is _________________________________ _______________________________________ There are two types of flagellates, _____________ & _______________. They are distinguished by the presence of _____________, which make food. Most Euglena are ___________________. flagellum a tail-like structure that propels the Euglena in water autotrophic heterotrophic chloroplasts autotrophs

a light-sensitive spot that detects light (red color) Section 6-4: The Euglena The Euglena has the following organelles: 1) Eyespot: ___________________________ ___________________________________ 2) Flagellum___________________________ 3) Chloroplasts: ________________________ 4) Nucleus: ____________________________ OTHERS: Pouch, Contractile Vacuole, Cytoplasm, & Pellicle a light-sensitive spot that detects light (red color) Tail-like structure for moving Makes food for Euglena Controls all functions
