Is a spruce tree monocot?

Neither, it is a gymnosperm (covered seed, coniferous (cone bearing) plants) . The terms monocot and dicot relate to angiosperms (naked seed, flower bearing plants)

Nope, it's an evergreen. :)

A spruce tree is a tree of the genus Picea. A maple is a tree of the genus Acer. The spruce is an evergreen and the maple is a deciduous tree

Spruce trees are softwoods and maple trees are hardwoods

Spruce is referring to trees of the genus Picea, a genus of about 35 species of coniferous evergreen trees in the Family Pinaceae, found in the northern temperate and boreal regions of the earth
