Wake-up
1.What did you notice about the “e” when
viewed under the microscope? Draw it.
2.What do you notice when you move the slide
to the right while viewing through the
eyepiece?

Eukaryotic Cells - Honors
Christopherson
Recall: Robert Hooke examined cork and
named the tiny boxes a “cell”
What is a cell?
The cell is the basic unit of life within living
organisms
Where is a cell in you?
Organism
That’s you
Where is a cell in you?
Organ systems
Where is a cell
in you?
Organs
Where is a cell in you?
Tissue
Where is a cell
in you?
Cell
What does this have to do with
Biology???
Inside the cell are
ORGANELLES(structures inside the
cell that perform specific function)
Eukaryotic Cell Definition
Complex cells that
have “membranebound” organelles.
“Membrane-bound”
means that they have
an outer layer.
Two main types of Eukaryotic Cells
1. Animal Cell
2. Plant Cell
What are some organelles in
animal and plant cells?
Nucleus
Location:
Function:Large
Control
circle
center
typically
of theincell;
the
middle
location
ofof
the
DNA
cell
Nucleolus
Location:
Function:Small
Makes
circle
ribosomes
inside of the
nucleus
Ribosomes
Location:Location
Small dots
all oversynthesis;
the cell
Function:
of protein
where proteins are made
Rough Endoplasmic Reticulum
Location: On the nucleus
Rough Endoplasmic Reticulum
Function: Perform the synthesis and transport of
proteins. Made up of a system of tubes, vesicles, and
covered with ribosomes
Golgi apparatus
Location: Within cell; stack of tubes
Golgi apparatus
Function: Processes and packages proteins and lipids
that are made; Similar to a post office
Wake-up
1. How can you tell the difference between a
nucleolus and nucleus?
2. What three organelles function that relates
to proteins? What is their difference?
Mitochondria
Function:
Breaks
down
sugar
into
ATP
Location: Throughout the cell
(usable form of energy); Powerhouse of
the cell
Chloroplast
Location: Green “beans” throughout a
Function: Location of photosynthesis;
plant cell
process by which plants make food
Vacuole
Location: Throughout an animal cell;
makes upStores
the majority
a plant
celletc.
Function:
water, of
food,
waste,
Lysosome
Location:
Throughout
a cell the cell
Function:
Gets rid
of waste within
Lysosome
Smooth Endoplasmic Reticulum
Location: On the nucleus and near the
Rough ER
Smooth Endoplasmic Reticulum
Function: Produces lipids such as steroids,
phospholipids
Cell/Plasma Membrane
Function: Control what comes in and out
Location: Outer layer of the cell
of the cell; gatekeeper
Cell Wall
Location:
Function:Outermost
Provide structure
layer in and
plant
support
cells
Cytoplasm
Function: Provides a liquid environment
Location:
Inside of
the cell and
for the various
dissolved
substances
some structure
Cytoskeleton
Location:
Throughout
an animal
cell
Function:
Provide
structure
and support
Nucleolus
Nucleus
Ribosomes
Cytoplasm
Cell Wall
Vacuole
Lysosome
Cell Membrane
Mitochondria
Chloroplast
What are the difference between an
animal and plant cell?
Differences
between
Prokaryotic
and
Eukaryotic
Cells
