That root-looking part is part root and part stem. The stem part (hypocotyl) pushes up above the top of the dirt. It looks like a whitish green upside down U when you first see it emerging from the soil. I think of it as the neck of the plant. The neck slowly rises up and pulls the first two beginning leaves with it. These leaves are beginning leaves, not real leaves. They are called cotyledons and were part of the apple seed itself. When the cotyledons are pulled up by the neck (hypocotyl) they usually bring up with them the covering of the apple seed. This brown apple seed covering eventually falls off.
