Is bacteria dead or alive?

It is alive.

Reasons:

It can reproduce, it eats, does not need a host to live (like virus which is dead), and it reacts to the enviroment. It has multiple functions and organelles in cells if it is a single or multi.

Also, alot of the answers you got are wrong. They are confused from avirus and a bacteria. It does not depend or it is not under debate.

Those guys are thinking of a virus.

Bacteria are alive. The reason is that they fulfil the 7 requirements of life. MRSGREN. Movemement (well some do), respriation, senstivity, growth, reproduction, excretion and nutrition.....yes to all these. Therefore we consider them alive (unlike viruses!!).

Depends

Very much alive. Bacteria is single-celled organism.

Alive. Responds to stimuli, and reproduces. Certainly alive.

Bacterium are alive...the ones they use in vaccines are usually weakened or dead though

...proof? Hit up wikipedia.com

Bacteria is alive.

They are microorganisms.

there is great dispute among scientists whether or not it is alive. think about the 8 charachteristics, and answer the question yourself.

it can be either, just like humans are dead or alive

bacterium is alive,even though they'r so tiny you need a micro-scope to see them,they're there.
