Transcript What is a Protist?

1.What is a Protist?
“A one – celled
organism that has a
nucleus.”
2. Why are protist
considered
While Bacteria are
considered
?
2 answer:
Protist have a
nucleus and
bacteria do not have
a nucleus.
3. Would you consider
the protist a more
advanced or a more
primitive organism
than the bacteria?
Why?
3 answer:
The protist is MORE
advanced than the
bacteria because it
has a nucleus.
4. What trophic level
are protist found on?
Pops note
Trophic level = how
Do they get food
4 answer:
Some protist are
consumers, some are
producers.
5. Define Protozoan:
Protozoan are animal
like protist.
6. List the three
traits of a
:
6answer:
(a)CONSUMER
(b)MOBILE (Can Move)
(c)Reproduces
7. Draw a colored
drawing of an
amoeba, label all the
parts:
7 answer:
8. Explain AMOEBOID
MOVEMENT in detail:
The amoeba sticks out a
pseudopod –
Pulls entire body into it
Sticks out another
pseudopod and does it
over and over again.
Define
9 answer:
The Pseudopod is a
“
”
Which is just an
extention of the cell
membrane.

Description:
The amoeba locates prey!
Surrounds it with its
pseudopods and engulfs it.
11.
Draw, color, and label
Paramecium traits:
(a)Definite shape
(b)Mobile uses cilia
(c)Brushes food into its
mouth with cilia
(d)Contractile vacuoles
remove extra water from
inside the cell.
12. Trypanosome:
Draw, color, label and
list traits.
1.A Mobile parasite!
2.Causes African
Sleeping Sickness
3.Spread by the
TseTse Fly
13. Sporozoans
Draw, color, label and
list traits
13.
(a)Grows from a
spore
(b)Parasite
(c)Immobile
What is a
“A sporozoan that
causes
13. Cont.
What is its VECTOR?
This sporozoan is
Spread by mosquitoes
14. LIST THREE
TRAITS COMMON TO
ALL PLANT LIKE
PROTIST:
15. List three plant
like protist:
16. Euglena:
Drawing, color, and
traits
Euglena Traits:
(a)Lives in oceans and fresh
water.
(b)No cell wall
(c)Moves with a flagella
(d)Photosynthetic
(e)Free living
17. Diatoms:
17.1 Where are
diatoms found?
Floating on the surface
of the ocean.
17.2 What is the
purpose of the
diatoms?
They are producers.
17.3 Three traits of
diatoms:
(a)Different shapes
(b)Glass-like outer
covering
(c)Floats at top of water
17.4 What is
17.4
Layers of diatom
shells that have been
dug up from the
ocean floor.
17.5 What is the
diatom earth used
for?
To scrape!
Toothpaste, scouring
powder, filters
18. Dinoflagellate
18. Three triats of the
dinoflagellate:
18. Answer:
• Plant like
(photosynthetic)
• Chlorophyll hidden by red
and brown pigments.
• Move by beating its two
flagella.
18. What is RED TIDE?
Sometimes, the red
dinoflagellates over
populate and begin to
move across the surface
of the ocean like a red
wave.
18. Why is Red tide
considered an
ECOLOGICAL
DISASTER?
As the red tide
passes over the
water, their body
waste kills all the
fish that are
underneath them.
19. What
is a slime
mold?
Slime mold traits:
1.Fungi like protist
2. Found on the Forest
floor.
3. Eats dead leaves,
and plants
20. List the three
stages of the slime
mold life cycle:
20 a. Feeds as individual
“amoeba like slime
molds.
Aggregates! (clumps
together”
Forms fruiting body that
produces the spores.
Fruiting
Body producing
Spores
Single
Slime molds
Aggregate
21. List two ways that
protist are helpful:
1.Food for other living
things
2.Some produce oxygen
during photosynthesis

23. 1
What organism
causes Amoebic
dysentery?
AMOEBA
23.2
WHERE IS THIS
ORGANISM FOUND?
In under developed
countries where
sewage gets in their
drinking water.
How do people get this
disease?
By drinking or bathing
in water that has
sewage in it.

dysentery?
There immune system
is strong enough to
resist it.

amoebic dysentery?
Weaker immune
system

dysentery?
NO IMMUNITY TO IT
AT ALL.
7. How can this
disease be prevented?
BOIL THE WATER
