YOU MUST KNOW… SOME DON’T CLASSIFY PROTISTS AS A KINGDOMHOW CHLOROPLASTS AND MITOCHONDRIA EVOLVED THROUGH ENDOSYMBIOSIS
CONCEPT 28.1 MOST EUKARYOTES ARE SINGLE-CELLED ORGANISMS
PROTISTS ARE… EUKARYOTES THAT ARE NEITHER PLANTS, ANIMALS, NOR FUNGIPROTISTS ARE PARAPHYLETIC – MANY ARE MORE CLOSELY RELATED TO PLANTS, FUNGI, OR ANIMALS THAN TO OTHER PROTISTS
PROTISTS VARY IN STRUCTURE AND FUNCTION MORE THAN ANY OTHER GROUP OF EUKARYOTES COMMONALITIES ARE: MOST ARE UNICELLULAR MOST USE AEROBIC METABOLISM AND HAVE MITOCHONDRIA
MITOCHONDRIA AND CHLOROPLASTS EVOLVED THROUGH ENDOSYMBIOSISTHEY WERE ORIGINALLY UNICELLULAR ORGANISMS ENGULFED BY OTHER CELLS THAT ULTIMATELY BECAME ORGANELLES IN THE HOST CELLS

Protist Kingdom - Ch. 15 p Droplets of pond water are filled with Protists! Protists are the first eukaryotes to evolve from prokaryote (bacteria)
Protists The Unicellular Eukaryotes. Some Basics: species difficult to classify no “ typical ” protist most aquatic, some terrestrial.

Chapter 28 - Protists. Important vocabulary pitfall.
Kingdom Protista Eukaryotes that are not members of the kingdoms Plantae, Animalia, or Fungi Characteristics –Live in moist environment –Either free-living.
PROTISTS The “Little Guys”. BUT… There are some general characteristics they all share: Unicellular (made of one cell) Unicellular (made of one cell)
Bellringer What are flagella and cilia used for?.
Protists. Characteristics: eukaryotic mostly unicellular may be plant-like, animal-like, or fungus-like in mode of nutrition (how they get food)

PROTISTS The “Little Guys”.
Protists What is a protist? Protist Diversity Diseases Caused by protists.
I. Endosymbiosis A. Occurred in early eukaryotes Pelomyxa - lacks mitochondria.
Endosymbiosis- Theory that the Evolution of the Eukaryotic Cell arose from the symbiosis of different species of prokaryotes. Protista=“the first” eukaryote.
3 Basic groups of Protists Fungus-like Slime molds, water molds Plant-like Algae, phytoplankton Animal-like Paramecium, amoeba.
Introduction to Kingdom Protista Domain Eukarya, Kingdom Protista –Any eukaryote that is not classified as a fungus, plant or animal Three major groups:
Protists- the hodge- podge group
Unit 6: Microorganisms and Fungi Chapter 20: Protists.
3 large groupings of Protists -protozoans (animal like) -slime molds and water molds (fungi like) -algae (plant like) Members of a Kingdom that is under.

Protists Chapter 8, Section 1.
Kingdom Protista Known as the “catch all” kingdom.
Protists. The Protists Protists are unicellular eukaryotic cells. (Unlike bacteria which are unicellular prokaryotic cells.) Do you remember the differences.
Protists Kingdom Protista. Characteristics of Protists most live in water (though some live in moist soil or even the human body) A protist is any eukaryotic.
Protists Domain: Eukarya Kingdom: Protista.
Kingdom Protista The most diverse kingdom. Protist The protist kingdom contains the most diverse collection of organisms.
Exploring Diversity Protists.
Prokaryotes Pro=before-Karyotes= nut (nucleus) These cells have no nucleus Examples: bacteria Eukaryotes Eu=good-Karyote= nut (nucleus) These.

Kingdom Protista. Weird things: has eukaryotic cells, so they aren’t bacteria or archaea doesn’t fit in with the fungi, plants, or animals either this.

Protists Section Kingdom Protista Eukaryotic – 200,000 species No simple set of common characteristics Can be unicellular or multicellular Microscopic.
Kingdom Protista The Kingdom that has all the eukaryotes that do not go in the other kingdoms.
In General Usually unicellular Reproduction: Some asexual, some sexual, some both Kingdom for life that doesn’t fit in animals, plant or fungi kingdom.
