kingdom protist edited

Protists are unicellular organisms that have a nucleus.

Unicellular One of the first groups of living things on

Earth. (1.5 billion years ago.) Microscopic Can cause disease. Can be parasites

Has a nucleus. Live in watery environment. Generally live as individual cells. Protists vary greatly in appearance and

function.

I. Animal-like Protists II. Plant-like Protists. III. Fungus-like Protists.

Protozoan means “First Animal”. Cells contain a nucleus. Cells lack a cell wall. They are heterotrophs. Most can move on their own.

1. Sarcodines (SAHR-koh-dighnz) 2. Ciliates (SIHL-ee-ihts) 3. Flagellates (FLAJ- ehl-ihts) 4. Sporozoans (spohr-oh-ZOH-uhnz)

Commonly called amoeba Have pseudopods (Greek:“false

feet”) Pseudopods are used for movement

and to capture food.

Contractile Vacuoles: controls amount of water inside

Food Vacuole: where food is digested.

They feed on bacteria and other protoctists.

Phagocytosis

Am0ebas reproduce by dividing into two new cells (binary fission).

They are sensitive to light and some chemicals.

ENTAMOEBA HISTOLYTICA

is an example of a pathogenic amoeba that can produce ulcers on intestinal walls and cause amoebic dysentery in humans

Are protozoans that move about by means of numerous hairlike cilia..

Free swimming ciliates

Reproduce by bf and conjugation

Have a Flagellum: a long whip-like structure used for movement.

Many live in animals

Based on the term spore, the infectious form in which the organism is transmitted from one host to another.

Pass from one host to another. Pass from ticks, mosquitoes or other

animals to humans.

Unicellular and Multicellular Colonies (groups of unicellular protists) Can move on their own Autotrophs: make their own food

from simple materials using light energy (photosynthesis).

Pigments: chemicals that produce color

Euglenoids (yoo-GLEE-noydz) Diatoms (DIGH-ah-tahmz) Dinoflagellates (digh-noh-FLAJ-eh-layts) Red Algae Green Algae Brown Algae

Green Unicellular Live in fresh

water Autotrophs, but

can be heterotrophs under certain conditions.

Flagella Eyespot:

sensitive to light.

Unicellular 10,000 living

species. Aquatic Glass like cell

wall

Unicellular Cell walls are like

plates of armor. Two flagella Spins when it

moves. Colorful

(pigments) Can glow in the

dark. Causes Red Tide

Multicellular seaweeds

Live in deep ocean waters

Used for ice cream and hair conditioner

Used as food in Asia

Most are unicellular Some form colonies Few are

multicellular Can live in fresh

and salt water and on land in damp places.

Very closely related to green plants.

Commonly called seaweed

Can contain brown, green, yellow, orange and black pigments.

Attach to rocks Have air bladders Used as food

thickeners

Heterotrophs Have cell walls. Many have flagella and are

able to move at some point in their lives.

Live in water or moist places.

Tiny threads that look like fuzz.

Attack food crops Caused the Irish

Potato Famine.

Reproduce by Fruiting Bodies:

The Fruiting Bodies contain Spores.

At first they look like ameba, then later they look like mold.

Live on moist shady places.

Feed on bacteria and other microorganisms.
