PROTISTSThey’re not plants

or animals!

KINGDOMPROTISTA

# of CELLSMOST ARE UNICELLULAR = ONE CELL

But some are multicellular!

Let’s see. You’re young, outgoing, single celled…

TYPE of CELLSEUKARYOTIC

Their cells have a nucleus and

other membrane bound

organelles.

GENETIC MATERIAL

They have DNA found inside the nucleus.

STRUCTUREThe protists are a very different

group!

There are very few common structures!

NOURISHMENTNot all protists are alike!

•Some are ANIMAL-LIKE PROTISTS. Heterotrophs that have to EAT food.

•Some are PLANT-LIKE PROTISTS: Autotrophs that can MAKE THEIR OWN FOOD.

•Some are FUNGUS-LIKE PROTISTS: Heterotrophs that DECOMPOSE MATERIALS.

Animal-like ProtistsAmoeba Paramecium

Giardia

Plasmodium (malaria)

Trichonympha

Plant-like ProtistsEuglena

Phytoplankton

Diatoms

Algae

Fungus-like ProtistsWater Mold

Slime Mold

REPRODUCTIONProtists reproduce ASEXUALLY AND

SEXUALLY!!!

LOCOMOTIONMost CAN move!

They all have a different way…EXAMPLES:•Paramecium: use cilia

• Made of microtubules

• Move by wave-motion

•Amoeba use pseudopods

• Move by extending

•Euglena use flagella

• Made of microtubules

• Move by wave motion

Passive Transport:

•Use spores

•Move by wind

HELPFUL Ex.• •Digest cellulose in termite

guts• •Algae & Phytoplankton are

a huge part of aquatic ecosystems!

• •Algae is used in nori, ice cream, salad dressing, pudding, candy bars, pancake syrups, eggnog, plastics, waxes, transistors, deodorants, paints, lubricants, and artificial wood.

• •Fungus-like protists play huge roles as decomposers in our ecosystem.

HARMFUL Ex.• –Plasmodium = Malaria• –Trypanosoma = African Sleeping

Sickness• –Entamoeba = Dysentery• -Giardia• –Water Mold = Potato Blight

Potato Blight

Trypanosoma
