Detailed explanation-4: -Angiosperms are the plants that produce flowers and fruits as a part of reproduction. The majority of gymnosperms are conifers, such as pine, fir, spruce, cedar, larch, and cypress. All of these trees have needles instead of leaves, and produce both pollen cones and seed cones in order to reproduce.

Detailed explanation-5: -All the pines, hemlocks, spruces, and firs are gymnosperms, one of the two main groups of spermatophytes, or seed plants. The second group, which includes the oaks, birches, maples, hickories, ashes and other familiar deciduous trees of the North Quabbin are angiosperms.
