This is a  picture of me and my tree.

 My tree is a gray birch.
It is deciduous because it doesn't keep it's leaves in the winter.
It is heart-shaped because looks like a heart.
It is simple because it is one lobe not multiple same reason why it's pinnate.
The branches are alternat because the branches are not even with eachother. 
It is also double toothed because it has small teeth on big teeth.
