Wake-up 1. What are the two bacterial kingdoms? 2.Explain the difference between the two kingdoms listed in #1.

Protist Kingdom Christopherson Watch Video

What is the Difference Between Prokaryotic and Eukaryotic? 1.Prokaryotic cells have no nucleus; Eukaryotic cells do 2. Prokaryotic cells lack membrane-bound organelles such as a mitochondria and chloroplast; Eukaryotic cell have them.

Protist Habitat: Freshwater (ponds, rivers, streams, etc)

Protist Habitat: Marine (Ocean)

Protist Habitat: Soil

Protist Habitat: In other organisms

Protozoa: Animal-like Protists AKA: Zooplankton

Zooplankton: Paramecium

Paramecium Structure Paramecium are unicellular

Paramecium Information* Move using Cilia – tiny hairs covering the outermost layer Cilia Watch Video

Paramecium Information ALL aquatic protists contain a contractile vacuole Acts like a water pump which regulates the water pressure inside organism

* Watch Video: Click picture

Method of Feeding* Heterotroph Cilia helps guide food into the gullet; a food vacuole is formed; digestive enzymes break down food Watch Video: Click picture

- One parent -Doesn’t exchange DNA - Produces identical offspring Reproduction: Binary Fission (Asexual)*

Reproduction: Conjugation(Se xual)* Two parents Exchange DNA Produce different offspring

Zooplankton: Amoeba

Amoeba Structure Amoeba are unicellular

Amoeba Information* Move using Pseudopod – False foot Literally moves like a blob Watch Video: Click picture

Method of Feeding* Heterotroph Pseudopod surrounds food; process called Phagocytosis Eventually engulfs it Fast forward to 1:15 Watch Video: Click picture

Brain Eating Amoeba* Watch Video: Click picture

- One parent -Doesn’t exchange DNA - Produces identical offspring Reproduction: Binary Fission (Asexual)

Protozoa: Plant-like Protists AKA: Phytoplankton

Phytoplankton: Euglena

Euglena Structure Euglena are unicellular

Euglena Information Move using a Flagella; a long whip-like tail Different species of euglena move in different ways

* They can spin like a tornado Watch Video: Click picture

* They can move like a worm Watch Video: Click picture

Method of Feeding Autotroph and Heterotroph Can undergo photosynthesis; has an eyespot to act as a sunlight sensor Also can consume food if necessary

-One parent -Doesn’t exchange DNA -Produces identical offspring Reproduction: Binary Fission (Asexual)

Phytoplankton: Dinoflagellates Dinoflagellates are Unicellular

Some have the ability to bioluminescence (glow) The ability to glow is similar to a burglar alarm or defense system

Phytoplankton: Diatoms Diatoms are Unicellular

- Diatoms cell wall contains silica (glass) -When they die their silica shells fall to ocean floor. It becomes diatomaceous earth

Phytoplankton: Green Algae Unicelluar; Multicellular; Colonial (many individual organisms living together in a outer membrane)

Most diverse group of protists; can be found everywhere

Even on the backs of some animals

Phytoplankton: Brown Algae Not a true plant because it lacks TRUE roots, stems, and leaves Frond≠Leaf Stipe≠Stem Holdfast≠Roots

Seaweed is an example of Brown Algae

Kelp is also an example of Brown Algae

Brown Algae is Edible
