ADD slide
• Pop up clues for pro vs. euk• ADD pictures!!!!!
Add slides with pictures of the organelles and have student verbally respond based on image…
• Ask students name and job• PLANTS AND ANIMALS BOTH HAVE
VACULOES…plants have one large central one
Add slide with different cell types with function for each
• Stems cells– What are they– Embryonic vs. adult comparisons
• Ask students name & function…key characteristics• SAME DNA…different genes turned on
– Give examples…• I am a cell with genes turn on to make proteins for: fast
communication, stretching, swimming….etc.• I use chemical messangers called neurotransmitter to send fast
messages around the body…
Sending messages
Unit 3 Reminders:
1. Cell specialization/differentiation:– Where do all cell originally come from (what type of
cell)?– Do all cells have the same DNA?– Do all cells have the same function (job)?– What makes a muscle cell and a nerve cell different?– REMEMBER: all cells have the same DNA, but
different jobs! The only difference are the GENES that are turned on or off in each cell – this determines their job!

ADD IMAGES OF ACTIVE & PASSIVE TRANSPORT….also addpic of trucks going up vs down hill…emphasize energy vs. no energy
NO YES
HIGH to LOW LOW to HIGH
Transport Reminders:
1. ALWAYS draw you box-circle model2. When the molecules CANNOT move it is OSMOSIS– WATER moves high to low– Use the salt concentration. Subtract from 100% (inside
and outside). The left remaining amount is the water concentration. Move the water from the high concentration to the low concentration.
3. If water moves…– OUT = the cell will SHRINK or SHRIVEL– IN = the cell will SWELL or BURST
100% water0% salt
20% salt80% water LOW (water)
HIGH (water)
Water will move out of the cell and it will SHRINK

0% salt

ADD pictures of homeostasis (shivering vs. sweating), monitoring amount of water salt, sugar, heart rate breathing etc. for body
Have pictures pop up and have students explain what is being balanced.
MAINTAINING BALANCE WITHIN AN ORGANISM
Homeostasis…What does it mean? Maintaining internal BALANCE
Explain why these are examples of HOMEOSTASIS:
Shivering when it’s cold out
Sweating when it’s hot out
Insulin released by the pancreas
Water balance in an organisms

REMINDER:SOLUTE = substance in the water(salt, sugar, etc.)
Real life application of osmosis…• What happens when you don’t water your
plants…
The VACUOLE loses water (water leaves the cell), so the cell SHRINKS or SHRIVELS, causing the plant to wilt and die.

THE SHAPE OF THE ACTIVE SITE
YES – ENZYMES ARE REUSED FOR THE SAME SPECIFIC TYPE OF REACTIONS, UNLESS THE ACTIVE SITE IS DENATURED (the shape is changed).
pH AND TEMPERATURE CAN DENATURE THE ACTIVE SITE OF THE ENZYME. IF THE ACTIVE SITE CHANGES SHAPE, THE ENZYME CAN NO LONGER PERFORM AT AN OPTIMAL LEVEL AND MAY STOP WORKING.

What we know:
Mom: Type A (AA or Ao)
Baby: Type O (oo)Dad: 1. Type AB (AB) 2. Type A (AA or Ao) 3. Type O (oo)
Narrowing it down:
If the child is blood Type O, then both parents have to give an ‘o’ allele.
This leaves means Mom has to be heterozygous Type A (Ao).Dad 3 could be the father because he is Type O (oo) and can give an ‘o’ allele.
Dad 2 could be the father only is he is heterozygous Type A (Ao), because he must have an ‘o’ allele to give.
Dad 1 could NOT be the father because he is blood Type AB (AB). He does not have an ‘o’ allele to give, so he cannot be the father of a child with Type O (oo) blood.
ADD image to show the difference
SKIN COLOR, HAIR COLOR, EYE COLOR
MULTIPLE ALLELES HAVE MORE THEN TWO ALLELES THAT CAN CODE FOR A DIFFERENT TRAITS, BUT ALL OF THE ALLELES ARE LOCATED ON THE SAME GENE. AN EXAMPLE OF MULTIPLE ALLELES ARE BLOOD TYPES (A, B, O).
POLYGENIC TRAITS HAVE MORE THEN TWO ALLELES THAT CAN CODE FOR A DIFFERENT TRAITS, BUT THE ALLELES ARE LOCATED ON THE DIFFERNT GENES. THIS CREATES A VERY WIDE RANGE OF PHENOTYPES. EXAMPLES OF POLYGENIC TRAITS ARE HAIR COLOR, EYE COLOR, AND SKIN COLOR.
Autosomal = because there are an equal number of males and females affected.
Recessive = because there are an equal number of males and females affected.

ADD pictures with answers
GENETIC ENGINEERING
THE DESIRED GENE (insulin) IS CUT OUT USING RESTRICTION ENZYMES.
THE DESIRED GENE (insulin) IS THEN GLUED INTO A BACTERIAL PLASMID (circuluar DNA) USING THE ENZYME LIGASE.
THE PLASMID (now recombinant DNA with the bacterial host and desired gene) IS INSERTED BACK INTO THE BACTERIAL HOST.
THE BACTERIAL WILL NOW PRODUCE COPIES OF THE DESIRED GENE EVERY TIME IT DIVIDES (using binary fission). So, the insulin gene is reproduced every time the bacteria divides.
FOSSILS ARE USED TO COMPARE AGE AND FETURES TO HELP DETERMINE COMMON ANCESTRY
COMPARING DNA, AMINO ACIDS, AND PROTEIN SEQUENCES TO DETERMINE COMMON ANCESTRY. FEWER DIFFERENCE MEANS A CLOSER COMMON ANCESTOR.
VARIATION IS NECESSARY FOR EVOLUTION. THERE MUST BE DIFFERENCES AMONG ORGANISMS IN ORDER FOR THERE TO BE COMPETITION. COMPETITION CREATES NATURAL SELECTION – THOSE WITH THE MOST FAVORABLE TRAITS FOR THE ENVIRONMENT SURVIVE AND REPRODUCE.
GEOGRAPHIC ISOLATION CREATES A PHYSICAL DIVIDE BETWEEN ORGANISMS. NATURAL PHYSICAL BARRIERS INCLUDE MOUNTAINS, LAKES< RIVERS, OCEANS AND ISLANDS. THE PHYSICAL SEPARATION MEANS THE ENVIRONMENTS ARE DIFFERENT. THE DIFFERENT ENVIRONMENTS WILL SELECT DIFFERENT TRAITS AS BEING BETTER FIT FOR THE SPECIFIC ENVIRONMENT.
SO, OVER TIME THE MOST SUCCESSFUL ORGANISMS WILL DIFFER IN APPEARANCE BASED UPON THE ENVIRONMENT THEY ARE IN. THE SPECIES ARE ALSO NO LONGER MATING, DUE TO THE PHYSICAL SEPARATION. OVER A LONG PERIOD OF TIME THE SPECIES ARE NO LONGER ABLE TO REPRODUCE WITH ONE ANOTHER TO PRODUCE FERTILE OFFSPRING. THIS CREATE A NEW SPECIES – SPECIATION.
THE ENVIRONMENT PLAYS A VERY IMPORTANT ROLE IN EVOLUTION. THE ENVIRONMENT SELECTS WHICH TRAITS AND ADAPTATION ARE BENEFITIAL TO AN ORGANISM. THE ORGANISM WITH THE DESIRABLE TRAITS SURVIVE AND PASS ON THEIR GENES.
EVOLUTION OF CELLS…No OXYGEN, which means NO PHOTOSYNTHESIS, which means organisms found food and did NOT make it
Anaerobic Heterotrophic Prokaryotic Cells
SUN, WATER & CARBON DIOXIDE available on early earth – the organisms use these to begin doing PHOTOSYNTHESIS
Photosynthetic Prokaryotic Cells
PHOTOSYNTHESIS creates OXYGEN – this allows heterotrophic organisms to make MORE ATP than with no Oxygen…
Aerobic Heterotrophic Prokaryotic Cells
Aerobic Heterotrophic Prokaryote (mitochondria) & Photosynthetic Prokaryote (chloroplast) form a partnership…(Endosynbiotic Theory)
Eukaryotic Cells
ABIOGENESIS = LIFE COMES FROM NON-LIVING THINGS
BIOGENESIS = LIFE COMES FROM OTHER LIVING THINGS
REDI
PASTEUR
VARIATION(Differences among members of the species)
Most with SHORTER necks
Occasionally some with LONGER necks
COMPETITION(More organisms than resources. Must compete for food, shelter and mates)
LONGER neck = easier time getting food
Food = survival
LONG NECK = BETTER TRAIT
LONG Neck giraffes more successful in obtaining food and mates
LONG neck gene is passed on because it is the more successful trait
Future generations look more and more like the successful traits – LONG NECK giraffes
NATURAL SELECTION
(Those with the best traits and adaptations for the environment are able to survive and reproduce.)
What happens if….• Lack of genetic variation (=lowered ability to adat to the
environment)– Mutations & sexual reproduction (MEIOSIS) lead to genetic
variation…• Geological isolation
– Put in polar vs. brown bear example &darwin finches…– Different env = different adaptations benefitial
• Reproductive isolation– Different mating times/different culture – food etc.
• Speciation examples• Pesticide & antibiotic resistance as example of natural selection
