Go back to your list of MICROBES/MICRO-ORGANISMS

MICRO-ORGANISMS = MICROBES BACTERIA VIRUSES PROTOZOA (protists) some FUNGI some PARASITES

MICRO-ORGANISMS = MICROBES BACTERIA VIRUSES PROTOZOA (protists) some FUNGI some PARASITES ONE of these things is NOT like the other!

MICRO-ORGANISMS = MICROBES BACTERIA VIRUSES PROTOZOA (protists) some FUNGI some PARASITES ALIVE!

MICRO-ORGANISMS = MICROBES BACTERIA VIRUSES PROTOZOA (protists) some FUNGI some PARASITES ALIVE! ALIVE! ALIVE! ALIVE!

MICRO-ORGANISMS = MICROBES BACTERIA VIRUSES PROTOZOA (protists) some FUNGI some PARASITES ** NOT ALIVE**

How are other microorganisms alive but viruses are not? http://archives.microbeworld.org/microbes/virus/

Let’s look again at scale here.

Viruses are tinier than bacteria. Compare.

VIRUSES ARE SO SMALL THEY ARE ALMOST AT THE MOLECULAR LEVEL http://learn.genetics.utah.edu/content/cells/scale/

VIRUSES ARE SO SMALL THEY ARE ALMOST AT THE MOLECULAR LEVEL

VIRUSES ARE SO SMALL THEY ARE ALMOST AT THE MOLECULAR LEVEL THEY ARE MUCH SMALLER THAN THE SMALLEST BACTERIAL CELL

VIRUSES ARE SO SMALL THEY ARE ALMOST AT THE MOLECULAR LEVEL THEY ARE MUCH SMALLER THAN THE SMALLEST BACTERIAL CELL And SINCE CELLS ARE THE SMALLEST __________ OF LIFE….

VIRUSES ARE SO SMALL THEY ARE ALMOST AT THE MOLECULAR LEVEL THEY ARE MUCH SMALLER THAN THE SMALLEST BACTERIAL CELL And CELLS ARE THE SMALLEST UNIT of STRUCTURE OF LIFE so IF VIRUSES ARE SMALLER THAN CELLS, they CAN’T be ALIVE.

LET’S LOOK AT IT ANOTHER WAY….

What separates the living….

What separates the living from the NON-living?

What separates the living….

What separates the living….

What separates the living from the NON-living? bacteria virus

What separates the living from the NON-living? Bacteria & protists viruses

What separates the living from the NON-living? bacteria & protists viruses

What separates the living from the NON-living? bacteria, protists, fungi viruses

What separates the living from the NON-living? bacteria, protists, fungi viruses

What separates the living from the NON-living? Bacteria, protists, fungi, plants, animals= ALL ALIVE viruses= NOT ALIVE!!

Compare & contrast… LIVING THINGS…. NON-LIVING THINGS…

Compare & contrast… LIVING THINGS…. NON-LIVING THINGS… ABSORB & USE ENERGY GROW REPRODUCE DON’T ABSORB & USE ENERGY DON’T GROW 3. DON’T REPRODUCE

Compare & contrast… LIVING THINGS…. NON-LIVING THINGS… ABSORB & USE ENERGY GROW REPRODUCE DON’T ABSORB & USE ENERGY DON’T GROW 3. DON’T REPRODUCE

If VIRUSES are NOT ALIVE, what of these 3 things CAN’T they DO? LIVING THINGS…. NON-LIVING THINGS… ABSORB & USE ENERGY GROW REPRODUCE DON’T ABSORB & USE ENERGY DON’T GROW 3. DON’T REPRODUCE

VIRUSES can absorb & use energy, they can grow (in numbers) BUT.. LIVING THINGS…. NON-LIVING THINGS… ABSORB & USE ENERGY GROW REPRODUCE DON’T ABSORB & USE ENERGY DON’T GROW 3. DON’T REPRODUCE

VIRUSES CAN’T REPRODUCE ON THEIR OWN, LIVING THINGS…. NON-LIVING THINGS… ABSORB & USE ENERGY GROW REPRODUCE DON’T ABSORB & USE ENERGY DON’T GROW 3. DON’T REPRODUCE

VIRUSES CAN’T REPRODUCE ON THEIR OWN. NOT ASEXUALLY NOT SEXUALLY

So, why are we so FREAKED-Out by something that can’t reproduce?

HOW CAN VIRUSES BE SO DANGEROUS if they CAN’T REPRODUCE?

Viruses are EVEN SIMPLER microbes than bacteria! No membrane, no cytoplasm, no ribosomes

Remember, viruses are really tiny Remember, viruses are really tiny. And VIRUSES are the SIMPLEST ORGANISMS. A VIRUS is ONLY some GENETIC MATERIAL (RNA or DNA) SURROUNDED by a PROTEIN COATING (capsid)

Remember, viruses are really tiny Remember, viruses are really tiny. And VIRUSES are the SIMPLEST ORGANISMS. A VIRUS is ONLY some GENETIC MATERIAL (RNA or DNA) SURROUNDED by a PROTEIN COATING (CAPSID) THAT’S IT: JUST SOME GENETIC STUFF in a HARD SHELL

Because they aren’t “alive”, they can do absolutely nothing for years. Like a volcano.

But IF A VIRUS CONTACTS A LIVING THING… Be you a bacteria, protist, tree or human!

But IF A VIRUS CONTACTS A LIVING THING, IT INJECTS ITS GENETIC MATERIAL INTO THAT CELL! Be you a bacteria, protist, tree or human!

But IF A VIRUS CONTACTS A LIVING THING, IT INJECTS ITS GENETIC MATERIAL INTO THAT CELL! Any unicellular or multi-celled creature is susceptible to viral attack! http://www.youtube.com/watch?v=RO8MP3wMvqg

Like a ZOMBIE PIRATE TERRORIST… VIRUSES HIJACK your cell!

What does that mean to the poor cell?

So, instead of your cell doing what it is supposed to do… like help you breathe if a lung cell. absorbing & using chemical energy thru diffusion & cell respiration

So, instead of your cell doing what it is supposed to do… like help you breathe if a lung cell. like help you move if a muscle cell. absorbing & using chemical energy thru diffusion & cell respiration growing thru protein synthesis

So, instead of your cell doing what it is supposed to do… like help you breathe if a lung cell. like help you move if a muscle cell. like help you feel if a nerve cell. reproducing thru mitosis, meiosis, or binary fission absorbing & using chemical energy thru diffusion & cell respiration growing thru protein synthesis

So, instead of your cell doing what it is supposed to do, your cell HOSTS a VIRUS PARTY!

A VIRUS REPROGRAMS A “host” CELL TO BECOME A VIRUS FACTORY! AND THIS AIN’T GOOD FOR THE CELL…NO WAY!!!

A VIRUS REPROGRAMS A “host” CELL TO BECOME A VIRUS FACTORY! AND THIS AIN’T GOOD FOR THE CELL…NO WAY!!! This “host” cell eventually fills up with little viruses until the cell EXPLODES and out comes more viruses ready for infection!

AND YOU CAN GUESS WHAT ALL THESE NEWLY CREATED VIRUSED WILL DO NEXT… NO, THEY AREN’T GOING TO PARTY…

And THESE MANY NEW VIRUSES NOW INVADE & HIJACK MORE OF YOUR CELLS. nasty little invaders!

And THESE MANY NEW VIRUSES NOW INVADE & HIJACK MORE OF YOUR CELLS. nasty little invaders! MORE of YOUR CELLS EXPLODE, RELEASING EVEN MORE ZOMBIE PIRATE TERRORISTS!

Many viruses like the HIV/AIDS virus hardly spends ANY time outside of your cells!

Many viruses like the HIV/AIDS virus hardly spends ANY time outside of your cells! YOUR CELLS LET THEM IN!

BIG DANGERS of VIRAL ATTACK!

VIRUSES can be NASTY!

3 COMMON PATHOGENIC/CONTAGION VIRUSES: FLU (influenza) COLDS CHICKEN POX

Thankfully, some even NASTIER VIRUSES are NOT as COMMON… EBOLA, HIV/AIDS, POLIO…

Let’s read about the ZIKA virus!!! http://www.medicaldaily.com/how-zika-virus-attacks-body-and-what-happens-after-infection-everything-you-393977

No treatment yet…only prevention. ZIKA reading activity…

but THANKFULLY some viruses can be helpful! http://www.cbsnews.com/news/using-polio-to-kill-cancer-60-minutes/ https://www.youtube.com/watch?v=ssHEtvUS9eU http://www.cbsnews.com/videos/how-the-polio-virus-is-being-used-to-fight-cancer/

GENETICALLY-ALTERED HIV VIRUSES are used to reprogram our T-cells (white blood cells) so they can attack cancer! GENETICALLY-ALTERED POLIO VIRUSES are used to attack cancer cells and trigger an immune response! BIOTECHNOLOLGY WOW!

GENETICALLY-ALTERED VIRUSES are used to HELP FIGHT DEADLY NON-INFECTIOUS CANCERS! BIOTECHNOLOLGY WOW!

BACTERIOPHAGES are VIRUSES that attack BACTERIA! https://www.youtube.com/watch?v=rzdwfwuVWUU https://www.youtube.com/watch?v=-w4C74cu6dk

BACTERIOPHAGE VID… LET’S MAKE A VIRUS!!!!

EACH CLASS WILL VOTE ON THEIR TOP 3 & THEIR WORST ONE TOO! TOMORROW EACH CLASS WILL VOTE ON THE OTHER CLASSES BEST AND WORST. THE CLASS THAT WINS THE MOST VOTING PER BLOCK WITHOUT HAVING THE WORST VIRUS WINS AN AUTOMATIC LAST CHANCE GAS!

What came first: bacteria or viruses? http://www.youtube.com/watch?v=TVLo2CtB3GA Are viruses nano-technology???? http://www.youtube.com/watch?v=sizO5XSnzCU FIRST 45 seconds

What other pathogens are out there????

man, how do we kill/destroy such microbes?
