Chapter 9: Section 1
 Protist-
An organism that lives in a moist or
wet habitat

Contains organisms that don’t fit anywhere else!
 ALL

PROTISTS
Have a nucleus (eukaryotic)
 SOME


PROTISTS
Single celled/Many celled
Make food/Consume food
 Otherwise
known as ALGAE
 All
contain chlorophyll make own food
 Some

Single-celled/many-celled
Are not green b/c a different pigment covers
chlorophyll
 Divided
into 6 phyla according to their
pigments and how they store food
 Common
name- Euglenas
 Characteristics:






Single-celled
Pigment is chlorophyll
Stores food as carbohydrates
No cell wall, but thick layer inside cell
membrane
Moves using flagella (whip like tail)
Has an eyespot that respond to light
 Common
name- Diatoms
 Characteristics:




Single-celled
Stores food as oil
Golden-brown pigment & chlorophyll
Cell wall is a glasslike shell made from silica
 Common
name: Dinoflagellates
 Characteristics:





Single-celled
Stores food as oil & starch
Red pigment & chlorophyll
Move with 2 flagellum causing it to spin
Many produce a chemical that causes them to
glow!
 Common
name: Green Algae
 Characteristics:



Single-celled and many-celled
Store food as starch
Contains only chlorophyll
 Common
name: Red Algae
 Characteristics:



Most are many- celled
Store food as starch
Contain red pigment that absorbs minimal light
 Common
name: Brown Algae
 Characteristics:



Many-celled
Store food as starch
Brown pigments & chlorophyll
 Diatom
shells are used in paints & make up
(make it shiny) and toothpaste (make it
abrasive)
 Red Algae is used in pudding and toothpaste
(makes them creamy & smooth)
 Brown Algae is used in ice cream &
marshmallows (makes thick) and is eaten in
sushi & salads
A
main food source for herbivores of the
water
 Provides oxygen through photosynthesis
 Otherwise
known as PROTOZOA
 All single-celled organisms
 Can’t make their own food (heterotrophs)
 Contain special vacuoles for digesting food &
ridding excess water
 Four phyla based on method of movement
 Common
name: The Amoebas
 Use a temporary extension of the cytoplasm
called a pseudopod to:


Move- extend a section out and drag forward
Eat- extension surrounds the food particle (endocytosis)
 Common
name: Flagellates
 Move by whipping one or more flagella
 Common
name: Ciliates
 Move by using cilia

Short threadlike fibers that beat back/forth
 Have
two nuclei
 Feed through an “oral groove”
 Have
no way of moving on their own
 Only survive as a parasite
Plasmodium is the
protist that causes
Malaria
 Good
Example: Waste water treatment
 Bad
Consuming bacteria
Disease causing
Examples: African Sleeping Sickness, Malaria,
dysentery (diarrhea)
The amoeba that
causes acute
diarrhea!
Trysanopoma among red
blood cells in someone
with Sleeping Sickness
 Have
features of protists and fungi
 ALL


Reproduce using spores
Obtain energy from decomposing organic
materials
 At
times use pseudopods to move and feed
like an amoeba
 Most of their life is spent acting like a fungus

Feeding on decaying matter and producing spores
 Protist
like b/c reproductive spores have
flagellum to move
 Fungus like b/c they grow as a mass of
threads over a plant or animal, digest it and
then absorb its nutrients
