READ AND LISTEN
CAREFULLY to everything!!
You should have two windows open at
this time. One for the presentation and
one for the questions on the form. Click
the link below to get the form to open.

Orange and yellow –
tell you when to pause
Or when do click on a link
Do activity
Or answer a question.
Mitosis - Meiosis
Cell cycle has 7 parts
IPMATC –
interphase, prophase, metaphase, anaphas
e, telophase, cytokenisis.
Interphase has three parts
○ G1 – S phase – G2

94.jpg
Miotosis is also
known as m-phase
This chart
is the cell
cycle
Remember the
cell cycle has
ipmatc
The green
purple and
orange arrow
represent g1, s-
phase and g2.
S-phase
means
“synthesis”
phase
•Interphase
•Arrows
•G1 S-phase
G2
•Mitosis
PAUSE – answer the following
questions on the form.
What happens during interphase?
Label and write what happens during the
three parts of interphase.
Mitosis – Meiosis cont.
Which part is mitosis –
○ PMAT -prophase, metaphase,anaphase, telophase
○ This picture is metaphase
○ PAUSE the video – go to the microscopes and count the cells in Metaphase
Ask the station manager for help
Come back and put answer on the form

After watching vid come back to the program
Osmosis Osmosis is diffusion
across a membrane
Diffusion is movement
from high
concentration to low
concentration.
PAUSE
Using diffusion – go to
“form 2” and answer
the diffusion questions
“expain why when
someone puts on lotion
you can smell it?”
High concentrationLow
concentration
With osmosis, hypertonic means there are more
solutes (solids) outside the membrane.
Water goes where the solutes are.
What happens to the cell when it is put in a hypertonic
solution?
○ PAUSE – go back and look at microscope A and
microscope B.
○ Both microscopes have a purple onion. Which onion
is in HYPERTONIC SOLUTION? A or B? How do
you know?
○ Answer on form 2
Cellular respiration
Two types of cellular respiration
One uses oxygen the other does not.
PAUSE – What are the two types of cellular respiration and
how many atp do they make?
○ Answer on the form.
Bacteria on
the head of
a needle
Looks like
Twinkies
We know that humans and
other animals use anaerobic res. and
aerobic res in the same
body.
Some bacteria don’t like
oxygen and some do.
So if you have a low oxygen
environment what organisms
are going to survive?
Bacteria!
PAUSE.
Go to the form and answer the
question, “what organisms can live in a
low oxygen environment.”
What organisms need an high oxygen
environment.
Biodiversity 1 and invasive
species The biggest reason different organisms die out (go extinct) is
because of habitat destruction.
Ex. Clear cutting
Land development
Building homes and businesses
Farming
When a habitat is destroyed the organisms die and biodiversity
goes down.
Biodiversity 2
The European
starling (left) is an
invasive species.
That means they are
not from here
They travel in huge
groups and eat all the
food.
This cause birds from
TN to starve and die.
PAUSE – go to the
form and answer the
question
“If an invasive
species of plants
grows faster than the
local plants what will
happen?”
Cells and organelles PAUSE – go to this link and study the
different organelles listed below. http://upper.usm.k12.wi.us/academics/faculty/rheun/organelle.html
While at that site study the function of… Nucleus
Mitochindria
Golgi apparatus
Rough ER
Smooth ER
Ribosomes
Chloroplasts
Cell membrane
Play the game below until you score a 90% or higher
– must show Mr. Taylor your score

GENETICS To the right is a
pedigree of a family
with color blindness.
As you can see the
females are carriers
○ The males either have
the defect or they don’t.
○ That means the defect is
“sex linked recessive”
GENETICS 2 Both the parents in the
Punnett square on the right are carriers for the disease green ear.
PAUSE – “do the parents have the disease?”
“how do you know”○ Now let us say the G represents
groovy hair.
○ PAUSE “what does that tell you about square 2 and 3?”
○ “what is the chance the offspring will not have groovy hair?”

The parents are
heterozygous or Gg
The sq 1 is
homozygous
dominant or GG
Sq 2 and 3 are
heterozygous or Gg
or Carriers for non-
groovy hair.
Cells use chloroplasts to
absorb energy from the sun.
PAUSE – what color do
chloroplasts reflect?
What colors do they absorb?
What is the speed of light?
