DENDROLOGY

Detailed explanation-1: -gymnosperm, any vascular plant that reproduces by means of an exposed seed, or ovule-unlike angiosperms, or flowering plants, whose seeds are enclosed by mature ovaries, or fruits. The seeds of many gymnosperms (literally, “naked seeds”) are borne in cones and are not visible until maturity.

Detailed explanation-2: -This pinnate leaf form is not found in any other gymnosperms. cycads are dioecious, meaning that there are separate male plants that produce pollen cones and female plants that produce seed cones. The cones of cycads are typically large, with many fertile, leaflike organs (sporophylls) that are aggregated into cones.

Detailed explanation-3: -Life Cycle of Gymnosperms Gymnosperms are vascular plants that produce seeds in cones. Examples include coniferssuch as pine and spruce trees. The gymnosperm life cycle has a dominant sporophyte generation.
