Without the glass the bulb will not have its shape so glass will always be there.

Not all bulbs use filaments. But I ve never seen a plastic bulb also or rather plastic bulbs are even more rare if at all there are any!. So its "FILAMENT".

Because of filament the bulb gets heated up when the current pass through it. As the filament gets heated up the heat we are able to see it as a light or illumination which is seen in visible range. So filament is the correct answer.
