What about sperm?
2007-08-15 00:25:52 · update #1
Bacteria are considered separate than as because they are not made by our body. Sperm on the other hand is made by our body, therefore it is part of us.

Our cells are considered 'us'. We are made of cells. Bacteria is sometimes considered a symbiant organism, an organism that co-exsists with us. We provide it a place to live and it provides a service in return. The E. coli bacteria in your intestines are an example. Other times, bacteria is an enemy of our body, such as a food poisoning by Salmonella bacteria. Either way, bacteria is a seperate 'being'.

The bacteria are considered separate because they perform actions like movement etc. at their own will.
Cells in our body act accordingly to the instruction given by the brain.For example, the cells in our leg muscles contract and relax when we want to move. They will not perform such actions on their own,unlike bacteria

Some bacteria can be considered foreign, just remember that other bacterias in the body are there for a reason, or a function, and can then be considered as part of our bodies, or simply just symbiotic.

maybe 9/10 of the cells in the human body are actually bacteria. but they're much smaller than human cells so they are not so great a proportion by mass. they are usually symbiotic or at least not harmful, but they are considered separate because they are extracellular and have separate genomes. mitochondria however are intracellular symbiotes of bacterial origin, and usually considered part of the human cell.

it is true that every cell lives for itself and bacteria too.but it can be called as a separate bpody because they form a unique system which is called organ system and puts us on the top most level of organization.

Tough one! I think it is a philosofical question, because all those cells could survive (if they are not killed by something else) on a strata rich in nutrients, and still they have a collective conciousness which, if all cells were changed over a period of time (which actually happens!!) it remains the same
