my favorite fruit is the apple.  the apple tree is a deciduous tree in the rose family best known for its sweet fruit.
I have heard that about apples, that its in the rose family, does that mean the same family as the flower roses?
NO! silly.. it is cultivated worldwide as a fruit tree, and is the most widely grown species in the genus "malus"
Oh okay, haha. What kind of apple is the most common or the most liked kind?
there areo ver 7,500 known cultivars of apples, resulting in a range of desired characteristics!
Oh wow thats a lot. When were apples first discovered? Or what region were they first found in?
it is not exactly known however they have been growin for thousands of years in asia and europe, and wer brought to north america by the europeans.
Oh okay thats interesting, I did not know that they were brought here! 
some people say that they have a mythological significants in many cultures such as the Norse, Greek and European Christian tradtions
Oh okay, I wonder what they would do or symbolize in mythology? Healing properties maybe?
