If it's a baby palm tree, yes. But if it's growing pretty big, you'll probably want to plant it outside. When it's a baby, and it's really hot outside, (Arizona), the sun heats up the pot and kills the tree. So if it's a baby, grow it inside.
yes, an apple pip will grow into a tree... apples normally have pips inside them and these pips are used so that they can produce an apple tree to make more apples. if apples didn't have pips inside them we wouldn't be able to produce more apples and this could cause to having no apples left!

You can grow an apple tree from seed. Each apple has from 1-10 seeds inside. However, it will take a long time.
