Detailed explanation-1: -Gymnosperms . The term gymnosperm (“naked seeds”) represents four extant divisions of vascular plants whose ovules (seeds) are exposed on the surface of cone scales. The cone-bearing gymnosperms are among the largest and oldest living organisms in the world.

Detailed explanation-2: -The word “conifers” means “bearing cones.” Conifers are plants that use cones to house their seeds. Conifers are woody plants and most of them are trees such as pine trees, firs, cypresses, junipers, cedars, and redwoods.

Detailed explanation-3: -Conifers are seed plants, and like most other seed plant groups they have wood, megaphyllous leaves, and of course seeds. These seeds are typically produced in woody cones, though the cones of some conifers are reduced to such a degree that they are no longer recognizable as such.

Detailed explanation-4: -Conifers produce their seeds in Woody cone structure. Trees which produce seed in the woody cone like structured are called conifers. There are two types of cone in conifers the male and the female cone.

Detailed explanation-5: -Gymnosperms are a group of seed-bearing plants that include conifers and cycads that produce “cones” as reproductive structures, one example being the well-known pine cone.
