Detailed explanation-1: -The largest group of gymnosperms are conifers, which comprise giant trees that can reach up to the height of 110 meters. They are the largest group due to the presence of six-hundred and thirty species of the total eight-hundred and sixty species of gymnosperms found on the planet.

Detailed explanation-2: -Comprising 550 species, conifers are the largest and most familiar group of gymnosperms. Conifers can range in size from tall trees, such as redwoods, to shrubs like yews and junipers.

Detailed explanation-3: -Zamia pygmaea is the smallest gymnosperm, and Sequoia sempervirens is the highest.

Detailed explanation-4: -Conifers like the spruce, cedar and pine tree are gymnosperms and have seeds on cones. Most coniferous trees are evergreen and are specially adapted to survive in areas with lots of snow. Many are cone-shaped to help snow slide off them so the branches won’t break.

Detailed explanation-5: -The sporophyte generation is most prominent in the gymnosperm life cycle. The life cycle of a gymnosperm begins on a mature sporophyte plant. Male spores grow into male gametophytes inside male cones.
