1. What are the characteristics of Kingdom Protista?

Simple organisms, eukaryotic, most are single celled, some are multicellular, many are colonial, cells never organize into complex tissues

Where do protists live?

They live in wet/moist environments (to survive), water or marshy land areas. Some live in water, some in soil

3. Describe three ways that protists get their food.

Autotrophic/producers (hotosynthesis), heterotrophic (eat other things), or both

How are protists grouped/classified?

how they move or if they can move, protist producers, protist heterotophs that can move, protist heterotrops that cannot move

What are algae?

answer

Why is algae in a seperate group from plants?

dont have complex tissues (roots, stems, leaves)

Red algae?

most of worlds seaweed, ususally less than a meter long, chlorophyll and red pigments (allows them to live at deeper depths

Green algae?

most diverse group, chlorophyll is their main pigment, live in variety of places, can get very large (8m)

Brown algae?

most of seaweed found in cold climates, chlorophyll, largest species of algae (50m)

Diatoms?

single celled, encased in symmetrical silica, two part shell, live in salt and freshwater, make most of worlds phytoplankton

Dinoflagellates

single celled, have 2 flagella

Euglenoids

Single celled, can be heterotrophic and autotrophic

Amoebas

single celled blobs, create food vacuoles to take in food, some are paracites, use pseudopods to move

Shelled amoebas

same as amoebas, are protected by a shell

Zooflagellates

can be parasites and they look like worms, use flagella to move, and they live in other living things and feed off of them

Ciliates

have little feet called cilia, help them move and eat

What is a contractile vacuole?

Is a vacuole that pushes water out of the cell

Spore forming

often parasites, can have complicated life styles, sometimes live in two or more hosts (malaria)

water mold

mostly small, single celled organisms, found in water, and are either decomposers or parasites

smile mold

can move in some parts of its life cycle but mostly do not, live in moist cool places usually where there is a lot of wood, all decomposers,
