aside from a few different Pokemon you can encounter in the 2 game, yes they are the same
Firered and leafgreen both can catch different Pokemon but there pokedex is the same, here is some examples: magmar only in leafgreen not firered, oddish in firered not leafgreen, ekans in firered not leafgreen, bellsprout in leafgreen not firered, pinsir in leafgreen not firered.
Yes :)
No. You can catch a Growlithe in FireRed in Pokemon Mansion on Cinnabar island. FireRed is the same as LeafGreen so you can catch it. ;P i have 2 of them
Basically they are the same - visit www.serebii.net for more info
You can't get mew in firered or leafgreen.
They're exactly the same.
you can't only in Pokemon firered and leafgreen you can't only in Pokemon firered and leafgreen
yes
In Pokemon firered you can't, but in Pokemon leafgreen you can get it then trade it to Pokemon firered.
Bellsprout has to be found wild, in leafgreen, you need to trade from Leafgreen for Pokemon.
Yes, unfortunatly!:(
