A tree is a woody plant that can grow to be 15 feet or higher and usually has a single stem and a crown (branched-out area) at the top.
Minnesota trees can be divided into two main types: deciduous and coniferous.
Deciduous trees drop their leaves each autumn. Deciduous trees are sometimes called angiosperms, broadleaf trees, or hardwoods. Oaks, maples, and elms are deciduous trees.
Coniferous trees are trees that produce seeds without fruits or nuts. Most coniferous trees bear seeds in cones, have needles instead of broad leaves, and keep their needles in winter. Coniferous trees are also called gymnosperms, evergreens, or softwoods. Spruces, firs, and pines are coniferous trees.
