if it comes from the ground up the why does it just shoot across the sky sometimes?

Both actually. Lightning has stepped leaders which originate in the bottom of the cloud and then they also originate from the top of the object that is about to be hit. This is the reason some say you feel like your hair is standing up right before you get hit. Once these two leaders meet somewhere halfway then the channel is formed and a dart leader shoots through the channel and then the channel lights up and the transfer occurs and this is the actual strike you see.

Both. But usually from the clouds to the ground. Read about Lightning storms http://physics.suite101.com/article.cfm/when_lightning_strikes

It comes from the ground. the ground's particles begin the charge then shoot upward to connect with the particles in the sky.

Usually- it goes from the ground UP... -Your science teacher needs to take a few refresher classes... :)
