From my book,
" osmosis is the diffusion of water molecules across a differentially permeable mebrane"
Why 要有differentially permeable mebrane 先叫 osmosis??
如果有2隻solution ( 其中一隻係water,) 有不同的concentrations, 咁佢地mix together, 咁higher water potential 會move to lower water potnential.
However, in this process 無 differentially permeable mebrane, 咁E 個仲係唔係osmosis??
what is osmosis?

If there is no membrane, it will be diffusion....

1for permeable membrane : well, that's the defination.
2of course theyy will. since their conc. r diff. note that the higher conc. , the lower the water potential.
3 no. told u that permeable membrane is the defination, same as why 1+1=2 , that's the defination of sum

if there is a differentially permeable membrane, other substance in the solution cannot move to the other side
in this case, this is not osmosis since there is absent of differentially permeable membranme
