Question

which correctly distinguishes between how a pine tree and an apple tree reproduce?
the pine tree bears flowers; the apple tree does not have any flowers.
the pine tree has unprotected seeds; the apple tree has seeds in fruit.
the pine tree is vascular; the apple tree is a seedless, nonvascular plant.
the pine tree is nonvascular; the apple tree is vascular.

Explanation:

Pine trees are gymnosperms, which have unprotected seeds (naked seeds) in cones. Apple trees are angiosperms, which have seeds enclosed in fruits.
Pine trees do not have true flowers (they have cone - like structures), while apple trees have flowers. Both pine trees and apple trees are vascular plants.

Answer:

The pine tree has unprotected seeds; the apple tree has seeds in fruit.
