DIVERSITY OF PROTISTS

“Junk Drawer” of the kingdoms

very diverse (lots of different

organisms are included in this

kingdom)

range in size [unicellular to multicellular]

variety of reproductive and nutritional

strategies

Can be heterotroph or

Autotroph

1. Animal like

Ex: Protozoans

2. Plant like

3. Fungus like

ANIMAL LIKE PROTISTS

(AKA: PROTOZOANS)

Resemble animals

Unicellular

4 Phyla (plural for

phylum)

Based on movement

HOW DO WE

SEPARATE

THEM INTO

PHYLA????

It is based on

how the

organism

MOVES

Draguesku Protists 0214

1. PSEUDOPODS

PHYLUM SARCODINA

EXAMPLE:

PSEUDOPOD (FALSE FOOT)

CONTRACTILE VACUOLE

Collects and expels H2O (excess) out of the Cytoplasm and

out of the cell

Amoeba engulfing an organism

WWW.PHSCHOOL.COM WEB CODE: CEP 1031 To see the amoeba move.

AMOEBAS

NUCLEUS

CELL MEMBRANE

FOOD VACUOLE

Draguesku Protists 0214

5

2. Cilia (Phylum Ciliophora)

Example: Paramecium

Cilia used for

locomotion

Contractile vacuole expels excess H2O

Macronucleus (large)

Metabolic processes

Micronucleus (small)

Gullet

pellicle

Reproduction

Draguesku Protists 0214

6

Reproduction of Paramecium

Asexual BINARY FISSION

Sexual CONJUGATION

Paramecia join together and exchange genetic

material

3. Flagella (Phylum Zoomastigina)

Can have MORE than one flagella

Example: Trichomymphia

Termites have a flagellate (Trichonymphia) in their

gut to digest wood

Draguesku Protists 0214

7

This is an example of:

Relationship in which

at least one species benefits

Another kind of relationship:

Relationship in which BOTH

partners benefit

Giardia (another example of a flagellate)

Parasite

Found in fresh water causes “hikers disease”

SYMBIOSIS

Mutualism

Draguesku Protists 0214

8

4. Sporozoans (Phylum Sporozoa)

NO MOVEMENT

Transmitted by another animal

PARASITES

Example:

PLASMODIUM MALARIA

Transmitted by mosquitoes

Draguesku Protists 0214

9

AKA: ALGAE

Habitat

.Ponds, lakes, oceans

Autotrophic

Produce much of the O2 in the atmosphere through photosynthesis

Provide food for the aquatic food chains.

Important food source for other aquatic

organisms.

Size

Unicellular and multicellular

Color

Varies depending on pigment (chlorophyll)

Green, yellow, red, brown, orange

& black

PLANT LIKE PROTISTS

Draguesku Protists 0214

10

Diatoms

Most numerous

unicellular algae in the oceans.

Important source O2

Made up of Silica component of

glass

Make up Diatomaceous Earth

Used for scrubbing and pool filtering agents

Dinoflagellates

Unicellular

Stiff plates (suit of Armour)

2 flagella

Glow in the dark (bioluminescence)

Draguesku Protists 0214

11

**some are responsible for the RED TIDE

that kills fish

Red tide bioluminescence

Draguesku Protists 0214

12

Euglena

Euglenoids

Green, Unicellular

Autotrophs

Can be HETEROTROPH when no

sunlight available.

Eyespot is light sensitive

Red Algae

Multicellular seaweeds

Carrageenan & Agar

Used as food

In Asia; toasted Fresh

or dried

Used in food products and other

products

Example: Ice Cream; hair

conditioner; Nori (sushi)

Green Algae

Ancestors to first plants

Cell wall contains cellulose

Has Chlorophyll

Green Algae

Has this in

common with

first plants

Great-Great-

Great

Grandma

We love

you

Grandma!!

Grandma

Green

Algae, you

started

everything!!

Draguesku Protists 0214

14

Green Algae:

Can live in colonies

Example: Volvox

Brown Algae

Commonly called Seaweed

Giant Kelp “forests”

Thrive in cool rocky water

Used for thickening (i.e. pudding)

Draguesku Protists 0214

15

The body contains:

Holdfasts for attachment

Blades and air bladders

that function in floatation

A stem like structure that

holds the blades is called

a stalk or stripe

FROND

BLADE

GAS

BLADDER

Also called

STIPE

Draguesku Protists 0214

16

FUNGUS LIKE PROTISTS

Heterotrophs

. Have Cell walls NO CHITIN

Use Spores to reproduce

Spores: Tiny cells that are able to

grow into a new organism

SLIME MOLDS

Live in forests and shady places on

decaying organisms

Draguesku Protists 0214

17

WATER MOLDS AND DOWNY MILDEWS

Grow as tiny threads that look like

“fuzz”

Water mold destroyed Irish Potato Crop

in 1845 & 1846.

Downey mildew Water mold
