Presentation Transcript

Slide1

Kingdom Protista (Protists)

Slide2

Protists are….

organisms that cannot be classified into any other group (plant, animal, fungus, bacteria)organisms that are typically made up of just one cellorganisms that can be made up of many cells

Slide3

Grouping Protists

Scientists struggle to group them

They are currently grouped based on how the obtain nutrition (food)

3 ways to obtain food = 3 groups of

protists

Digest food internally (consume food) =

Protazoan

Capable of producing their own food = Algae

Obtain food externally (break down decaying material) = Slime Molds

Slide4

Protazoans (Animal Like Protists)

Grouped based on how they move:Sarcodinians – move with lobes of cytoplasm (pseudopodia) that extend outwardZooflagellates – move by flagellumCiliates – move by cilliaSporozoans – require presence of a host to move

Slide5

Algae (Plant Like Protists)

Grouped as unicellular or multicellular:Unicellular:Multicellular:Algae provide environment with oxygenAlgae serve as a major food source

Slide6

Check for Understanding

With your partner, explain how protozoans are different from algae.

Some key differences include: protozoans consume food while algae make their own food, protozoans are grouped based on movement while algae are grouped based on number of cells, algae are mainly found in aquatic systems while protozoans can be found in a variety of locations, algae appear to be very beneficial and some protozoans are harmful.

Slide7

Slime Molds (Fungus Like Protists)

3 types:Acellular slime molds Cellular slime molds Water molds Saprophytic – grows on and takes nourishment from dead or decaying matter
