It is a membrane having holes

[Sachin@2210]

It is a membrane having holes or it is a membrane that has holes

Which is correct? And why?

I'd use the second and use grammar as the spelling.

1. It is a membrane having holes. or
2. It is a membrane that has holes.

Which is correct no question mark here and why?

Note my corrections above. When you give us more than one sentence to look at, put them on separate lines and number them.

Without context, it's hard to say definitively but sentence 2 is certainly grammatically correct and sounds like something a native speaker would say. They might also say "It's a membrane with holes [in]".

@Tdol - I suspect this was intended for a different thread.
