Transcript How does the protist population interact with it`s environment?

WARM UP
In
your warm up
notebook, Draw and
explain the stages of
how a virus reproduces.
How does the protist population
interact with its environment?
First, Let’s refresh your memories

What are the 7 levels of classification? And the
sentence to help you remember?


What are the 6 characteristics of life?


King Phillip Came Over For Great Spaghetti.
Kingdom, Phylum, Class, Order, Family, Genus,
Species
Grow, has cells, reproduce, respond to
environment, use energy, evolve
On a microscope, what objective do you start
on? What adjustment do you turn?

Smallest powered one, Coarse adjustment: aka the
big one

What are the kingdoms of bacteria and what is
classified in those?


Is bacteria alive?


YES
Is a virus alive?


Eubacteria: common bacteria, found everywhere.
Archaebacteria: old bacteria, found in extreme
environments
NO
Does bacteria make a virus?

NO
Protist, what is it?
Protists belong to the Kingdom Protista,
which include mostly unicellular
organisms that do not fit into the other
kingdoms. “Junk Drawer” Kingdom
 A protist is any organism that is not a
plant, animal or fungus

Characteristics of Protists
Mostly unicellular, some are multicellular
(algae)
 can be heterotrophic (can’t make own
food) or autotrophic (make own food)
 most live in water (though some live in
moist soil or even the human body)
 ALL are eukaryotic (have a nucleus)

Amoeba
Moves using pseudopods ( "false feet" ),
which are extensions of the cytoplasm.
 Animal-like cell, heterotrophic.

Watch an ameba!

endoplasm
What those parts do!






1. Movement and trap food (pseudopods)
2. Let’s things in and out of cell.(cell
membrane)
3. Where food is digested .(food vacuole)
4. Collects excess water and squirts it out.
(contractile vacuole)
5. Has DNA. Is the control center (brain)
(nucleus)
6. Filling for cell. (endoplasm)
Plant-Like Protists
Commonly called algae
 Autotrophic
 Types:

Green, red, brown algae
 Diatoms
 Dinoflagellates
 *Euglenas

Euglena
 Euglena
is a bright green in
color, a unicellular organism that
lives in freshwater.
 Can be described as a protozoa
with mixed characteristics of
both plant and animal.
Plant and Animal?
 Euglena
are autotrophs since
they make food from sunlight
(photosynthesis) and
 Heterotrophs
since they ingest
food from surrounding water.
Euglenas
They are similar to plants because they
can prepare their food by
photosynthesis.
 Their resemblance with animals lies with
the fact that it can move around from one
place to another.

Functions
1. Movement (flagellum)
 2. Finds light so cell can do
photosynthesis to make its own food.
(eyespot)
 3. Food- making factory (chloroplast)
 4. Holds shape and allows “in and
out”(pellicle)
