DENDROLOGY

Detailed explanation-1: -Gymnosperms are the seed-producing plants, but unlike angiosperms, they produce seeds without fruits. These plants develop on the surface of scales or leaves, or at the end of stalks forming a cone-like structure.

Detailed explanation-2: -Cone-Bearing Plants, or Gymnosperms Common cone-bearing plants examples are ginkgos and conifers, like pine trees, redwoods and palm trees. These types of plants are called gymnosperms, and they were the first of the seed-bearing plants to evolve.

Detailed explanation-3: -By far the largest group of living gymnosperms are the conifers (pines, cypresses, and relatives), followed by cycads, gnetophytes (Gnetum, Ephedra and Welwitschia), and Ginkgo biloba (a single living species). About 65% of gymnosperms are dioecious, but conifers are almost all monoecious.

Detailed explanation-4: -Gymnosperms are vascular plants that develop uncovered seeds. The main group of gymnosperms is the conifer. Conifers produce seeds in cones. Conifers are major lumber and paper producers.
