That's not a transistor. It's a capacitor. Capacitors charge when they receive power. Once they're charged, they emit voltage to reduce ripple. In most scenarios, they are grounded on one side.
What this means for you is that the board/chip will most likely work without the cap there at all. It can, however, effect the stability of the system since certain component(s) will not be receiving "clean" power.
Here's a quick figure to show what capacitors do:
For the most part, superglue has a very small chance of actually doing anything other than holding the cap in place. If you know anyone who is experienced at soldering, this is actually a relatively easy fix. The most difficult part is that you have to use a very high heat iron and it has to be done quickly. The solder used in the electronics industry is lead free and has a very high melting point, so it's much more difficult to get it to flow than standard run-of-the-mill solder. It has to be done quickly because surface mount capacitors can be damaged from prolonged exposure to high heat, usually in the form of cracking.
For someone with any experience, though, this is a two or three minute fix that's relatively low-risk. If the cap cracks, you can just get another. They're not hard to find and they're not expensive.
