microorganism

[maniesss]

hi everyone...

actually i'm new here in this forum.. i'm a math teacher in primary school... but then this math teacher had been ask to teach science next year... and i really think that is a problem for me... because i think that i have lack of science knowledge.. i hope evryone here can help me improve myself in science..

first question, is virus a microorganism??

second question, can somebody give me useful url where i can learn science?

thanks everyone for your coorperation..
i really appreciate it

you can start out with our tutorial section: http://www.biology-online.org/tutorials/home.htm

[honee_v]

for an overview (about viruses) check out these links
http://www.biology-online.org/dictionary/Virus and
http://en.wikipedia.org/wiki/Virus

thanks a lot honee_v...

i'll try my hard to study all this science stuff..

i read trough WIKIPEDIA i found this statement..

"Microorganisms can be bacteria, fungi, archaea or eukaryotes, but not viruses and prions because they are generally classified as non-living."


and i found this in biology-online..

A microscopic organism, those of medical interest include bacteria, viruses, algae, fungi and protozoa.
Retrieved from "http://www.biology-online.org/dictionary/Microorganisms"


So.. I don't know which one is the correct definition.. i am affraid that i'll explain the wrong thing to my student...

can somebody please help me about this...?

An organism must be a living creature. Since viruses are not alive, they cannot be microorganisms.

I have read that the reason that most scientists classify a virus as not alive is basicly because it can't grow or reproduce on its own w/o host.

[victor]

Yes, viruses are classified as non-living things, since they can't live without hosts. Viruses have a really close realtionship with microorganisms, but once again it's stated that "viruses are not living things, thus they're not organisms" .

[Poison]

virus thing has been discussed previously. make a search.

thanks a lot... for all the advise..
sorry for my late reply because of internet connection problem..

so... maybe i will explain to my student a simple way... that they should remember for the exam..

because in our textbook they said,
the process that microorganism (virus, fungi, bacteria and protozoa) undergo are :
1 - breathe
2 - grow
3 - moves
thats all...

but for the knowledge, i will let them to know the discussion on that matter


thanks a lot,
maniesss

When you do your background research, don't expect the rules in biology to be as precise as mathematics. It can be frustrating to people who like structure in their material.

For instance, although there is disagreement over whether viruses are alive, even biologists that think they are would be reluctant to call them micro-organisms.

But they're usually included in the grouping "microbes."

According to my knowledges,viruses is classified as the borderline of livingthings and non- livingthings. Viruses is considered a livingthings because it can undergoes reproduction in a host. Viruses is classified as non-living things because it do not carry out any metabolism process such as respiration,excretion and digestion.
