OK i don't know if this should be in biology category but is there any such thing as silicate based life form?

Answer 1

No. There was a theory, based on the fact that carbon and silicon usually both bond with 4 electrons.

However, the bond between two carbon atoms is much stronger than the bond between two silicon atoms.
The complex molecules needed for carbon-based life don't have silicon-based analogs, because those molecules would be too unstable.

Answer 2

only in science fiction

no silicate based life forms have been discovered

there is speculation about it because silicon has some of the same properties that make carbon such a remarkable atom for molecular structures and results in all known life forms being carbon based

Answer 3

So far to date there is no such thing as a silicate life form. There have been sci-fi stories though that have addressed this idea. So far all life as we know it is carbon based... but with so much silica out there.......

Answer 4

Silicon could possibly replace carbon as a basis for life, but it would have to be at a much higher temperature. Silicon bonds at terrestrial temperatures are too rigid for any type of "organic" chemistry to happen (think rocks). At a higher temperature silicon would be more reactive, so silicon-based life might be possible.

Answer 5

Only in science fiction, but scientists have propsed the idea of it, because it has a similar valency to carbon

Answer 6

we are carbon based lifeforms and so is everything else on earth so im gonna go with no
