CELLS!
•What is the
structure and
characteristics
of the lipid
bilayer?
• The basic building block of the
membrane is a phospholipids.
• has a head and two tails.
• head = hydrophilic, tail =
hydrophobic.
• form a double layer (a bilayer).
• stop polar molecules (+/-) from entering
the cell. different parts of the membrane
communicate inside and outside of the
cell.
• Lipid bilayers are fluid, they float around
like inner tubes
CO - Students will learn the major functions of the cell membrane.
LO - Students will think-pair-share for Ch. 8 interactive reading.
CELLS!
•Why is water
important?
•All cells are surrounded by water, with water
inside as well. Water is needed for hydration.
•The interaction between lipids water shapes the
cell membrane.
•Water is polar one part is positive, one part is
negative, so water molecules attract each other.
•Oil and water…
CO - Students will learn the major functions of the cell membrane.
LO - Students will think-pair-share for Ch. 8 interactive reading.

CELLULAR COMMUNICATION
•HOMEOSTASIS!
•WRITE THIS
DOWN!!!
•Cells want to be BALANCED!
–Hypertonic – concentration is greater
OUTSIDE of the cell, causing cell to lose fluid
and shrink
–Hypotonic – concentration is greater INSIDE
the cell, causing the cell to get bigger.
–Isotonic – Water moves in and out, cell stays
the same shape.
DRAW THESE!
CELLULAR MOVEMENT
•What are the
types of cell
movement?
•Cells are the smallest unit that can sustain life
so they need to “live” (eat, metabolise, etc..)
•There are 2 main avenues of movement
•First = Passive Transport – Does not
require energy
•Diffusion – The movement of molecules from a
high concentration area to low concentration area
(homeostasis) Diffusion is “toll-free”.
–Osmosis is the diffusion of water. Cells allow
water to pass freely to keep cells balanced.
Plants have cell walls to help hold water
without bursting.
C.O. – Students will explore the selectivity of semipermeable

Cell Cycle
•Describe the cell
cycle.
•Each cell goes through its own
cycle.
•Most of a cells life is spent in the 3
subphases of interphase.
•The M phase (mitosis phase), G1
(gap 1, growth) is the first phase of
interphase, S phase (2nd phase of
interphase) is where DNA is
synthesized (replicated), G2 (gap 2,
growth and preparation for mitosis).
CO- Students will learn the distinct parts of interphase.
LO- Students will produce a graphic organizer of interphase.
CO- Students will learn the distinct parts of interphase.
LO- Students will produce a graphic organizer of interphase.
No cell lives forever.
•Cell cycle vs
Cancer.
•Cell cycles can be triggered by genes or
other proteins.
•Faulty cells (cancer cells) never stop
replicating, spread throughout the body,
shutting it down, killing the organism.
•Cancer cells break away from main cell,
travel to other parts of the body and
replicate there as well. This is called
metastisizing.
CO- Students will
learn the distinct parts
of interphase.
LO- Students will
produce a graphic
organizer of
interphase.
•Most cancer cells have been found to have
defects in the gene that regulates cell
division.
•Mutations can cause cancer cells.
Factors can be environmental agents,
and chemical agents (like cigarette
Mitosis 6.2
•Describe the
•In order to survive and
process of mitosis reproduce cells must divide.
•When cells get to be a
certain size it either stops
growing or divides.
•Eukaryotic cells divide to form
2 nuclei to make 2 identical
copies.
•This process is called
MITOSIS. (MI-TWO-SIS)
Animation
• (interphase)
• Prophase
• Metaphase
• Anaphase
• Telophase
• cytokinesis
Mitosis
Mitosis
•Describe the 5
stages of mitosis
•Cells spend most of their lives in
“interphase”. Interphase is the time
between each cell division.
•“inter” comes from latin meaning
“between” so interphase really means
the “between” phase. Interphase can
be minutes, days, or years for some
cells. Nerve cells and some muscle
cells never complete a cycle.
•Right before mitosis the DNA copies
itself so that each cell will be identical.
•“INTERPHASE” is sometimes
considered the first stage of mitosis…
•PROPHASE
•Prophase is the first phase of
mitosis.
•Chromosomes coil, the nuclear
env. Breaks apart, and protein
spindle fibers (called microtubules)
from the centrosomes assemble
across the cell directing the
chromosomes where to go.
Mitosis
•METAPHASE
•Metaphase is the second
stage of Mitosis.
•(some call it the third stage only when they
count “interphase” as the 1st phase)
•Chromosomes line up in the
center of the cell and attach
themselves to the
microtubules.
Mitosis
•ANAPHASE
•Anaphase is the 3rd stage of
mitosis.
•Each chromosome separates
in half (into chromatids) and
they are “reeled” in like a fish
on a fishing pole towards the
opposite sides of the cell.
•Microtubules begin to break
down.
Mitosis
•TELOPHASE
•Telophase is the 4th stage of
Mitosis.
•In Telophase each cell now
has a complete set of
chromosomes, the nuclear
envelope forms around them
and they uncoil so proteins
can be built.
•Microtubules dissapear
Mitosis
•CYTOKINESIS
•Cytokinesis is the final stage
of Mitosis.
•Cytokinesis is where the
cytoplasm of the cell is
pinched creating 2 identical
cells.
•These 2 new cells are then
free to divide again on their
own etc…

3. List the 5 steps in order, of mitosis.
4. Draw a pie chart from memory to describe the order
of the entire life a cell including the subphases of
interphase.
5. In which phase does a cell spend most of its life?

You will have a mitosis quiz on Friday (please write it on your
HW calendar!), study life cycle of the cell (interphase (G1,S,G2))
and mitosis (prophase, metaphase, anaphase, telophase) and
cytokinesis.
You should also know generally what happens at each phase of
mitosis.
If you have not turned in your mitosis worksheet please turn it in
now.
C.O. – Students will understand the
components of DNA and how they affect
organisms.
L.O. – Students will work together coloring
and labeling distinct nucleotides and discuss
the level organization of heredity.

Chromosomes
•Describe the
structure and
function of
chromosomes…
•Chromosomes are like Google…TONS of
information stored in one convenient place.
Google has ONE site to search for everything.
•There are 46 chromosomes (in pairs) in almost
every cell in your body.
•Each “pair” is almost identical, containing
the same genes in the same order.
•Down syndrome (called trisomy 21) is where
you have an extra chromosome in the 21st “pair.
•Trisomy 18
•trisomy 13
•Down Syndrome has 3 main characteristics
•Physical, medical, and cognitive (developmental).
· A flattened appearance to the face
· A high, broad forehead
· A smaller head, proportionately
· An upward slant to the eyes
· A narrow slit to the eyes
· Pronounced bags or folds under the eyes
· A small, depressed nose
· Small ears
· Ears set quite low to the face
· A small mouth
· A large or protruding tongue
· A short neck
· Short arms and legs
· Short fingers and toes
· Large space between the first and second toe
· A single, deep crease in the center of the palm
· Poor muscle tone (hypotonia)
· Loose joints (hyperflexability)
· Weak reflexes

Mitosis and meiosis worksheet
Standard 2a
a. Students know meiosis is an early step in
sexual reproduction in which the pairs of
chromosomes separate and segregate
randomly during cell division to reproduce
gametes containing one chromosome of each
type.
b. Only certain cells in a multicellular organism
undergo meiosis.
c. How random chromosome segregation
explains the probability that a particular allele
will be in a gamete.
Mitosis Quiz!
• Please use the next 6-10 minutes to study
for your mitosis quiz.
• You will turn in your mitosis homework so
make sure it is finished!!!
C.O. – Students will illustrate the differences
between the process of meiosis (sexual
reproduction) and mitosis (cellular division)
L.O. – Students will read and discuss the
text, take notes and diagram mitosis and
meiosis.

It is carried out in all tissues that require cell replacement
It occurs only in cells in the reproductive structures of the
organism
It happens in all tissues except the brain and spinal cord
It is the first stage of mitosis.
Which element from the periodic table is essential for
building amino acids/proteins?
What is the difference between a scientific theory and a
hypothesis?
During which phase of mitosis does the cell split into 2
identical cells.
Which “phase” does a cell spend most of its lifetime in?
In order, starting with mitosis, what is the lifecycle of a
cell?
In class work ch. 11.1
• On the left hand side:
• Vocabulary:
– Gamete, zygote, diploid, haploid, fragmentation,
asexual reproduction, homologous chromosomes,
autosomes.
• Questions:
– 1, 2, 3, 4, 5
• Try to keep to one page. Write small and be concise.
DON’T JUST COPY, write in your own words.
• Remember to get full credit, you must include the page
numbers for where you found your answer.
• QUIZ TOMORROW ON THOSE VOCABULARY WORDS,
WRITE ON HW CHART!
• And remember your DNA packet is due today…
Chromosomes 6.1
•Describe the
structure and
function of
chromosomes…
•Chromosomes are like Google…TONS of
information stored in one convenient place.
Google has ONE site to search for everything.
•There are 46 chromosomes (in pairs) in almost
every cell in your body.
•Each “pair” is almost identical, containing
the same genes in the same order.
•These pairs are called diploid (di means 2)
because they contain both (or full set of)
chromosomes.
•A haploid cell (an “n” cell) contains only 1
CHROMATID (half) of the chromosomes of
that organism.
•A gamete (sex cell) is a haploid cell that
contains the genetic info from a parent
Sperm (haploid) + egg (haploid) = diploid..you!
Chromosomes
•Describe the
structure and
function of
chromosomes…
•Chromosomes are located in a cells
nucleus.
•Each chromosome contains one long thread
of DNA (if spread out would be about 5cm
long) that is wound around proteins
(hairdryer!)
•DNA has 2 strands wound together that
contains all the info necessary for that cell.
•Each DNA strand has its own order of
nucleotides bonded together. Its like having a
combination lock…hundreds of combinations.
•But DNA has 3,000,000,000 nucleotides so that
would be 4x10 3,000,000,000 combinations.
•Its like having a lock with 3,000,000,000
numbers on it.
