The Guts of an “Animal Cell”
Animal Cell Membrane
• Unlike the wall of the
restaurant business,
the plasma
membrane is quite
flexible and allows
the cell to vary its
shape.
Cells must have boundaries!!
• Cell membranes or plasma membranes are
made of fats, proteins and cholesterol.
Functions of the Cell Membrane
1. Boundary between the inside and
outside of the cell.
2. Controls movement of materials going in
and out of the cell. For instance, waste,
water, organic compounds and protein.
3. Helps to maintain a chemical balance
within the cell.

membrane on

Our Manager “Mr. Nucleus”
• Just like the
restaurant
business, the
cell needs a
manager
within its
boundaries.
The manager
directs the
affairs of the
business.
The nucleus is the organelle that
manages cell functions.
The Nucleus Continued…
• The nucleus contains DNA (Deoxyribose
Nucleic Acid), the master instructions for
building proteins. DNA forms long strands
called chromatin which can form
chromosomes when cells reproduce.
DNA
Nucleus
Nuclear Envelope
• The nucleus is
surrounded by a
nuclear envelope,
which is a double
membrane. Each
membrane has two
layers.
Ribosomes
• Inside the nucleus is
the nucleolus, a
region that produces
tiny cell particles
called ribosomes that
are involved in
building proteins.
Ribosomes are
organelles but do not
have a membrane.
Where are ribosomes located in cells?
Functions of the Nucleus
• Contains and processes genetic
information, controls cell
metabolism and protein synthesis.
Functions of the Nuclear
Envelope/Membrane
• Separates nucleus
from surrounding
cytoplasm.
Functions of Chromatin
• Regulates protein
building and other
molecular
interactions.
Functions of the Nucleolus
• Location where
ribosomes are made.
The cell manager…
• Color the nucleus,
nuclear envelope,
chromatin and
nucleolus now!
Cytoplasmic, Baby!!!
• Just like the restaurant with hallways and
rooms, the cytoplasm is used for
assembly, transport and storage of
materials.
Cytoplasm is:
• a media for transporting intracellular
substances
• contains storage vacuoles and vesicles to
store nutrients and waste
• contains enzymes needed for metabolic
reactions.
Color the cytoplasm now!
It’s Cell Quiz Time!!
• Get ready to play.
• Have one member represent your team in
answering the question.
• You will have 15 seconds to answer.
• Only one answer is to be given.
• Each answer is worth 3 points.
• Bonus question is used for a tie breaker.
Let’s Play!!
Question #1
• What organelle is responsible for holding
all the genetic information, or blueprints, of
the organism?
Nucleus!!
Question # 2
• Which organelle is responsible for what
material (protein, organic compounds,
water) goes in and out of the cell?
Cell Membrane or Plasma
Membrane
Question # 3
• What organelle does not have a
membrane surrounding it?
Ribosomes!
Question # 4
• What is the organelle that has two
membranes?
Nuclear Envelope
Question # 5
• Where are ribosomes made?
Nucleolus
Question # 6
• Where are organelles and the
cytoskeleton found and intracellular
materials transported?
Cytoplasm!
