Detailed explanation-1: -Broadleaf species such as oak, hickory, ash, maple, walnut, etc. are angiosperms. Needle-leaf species such as pine, spruce, fir, hemlock, baldcypress, larch, etc. are gymnosperms.

Detailed explanation-2: -The angiosperm life cycle typically demonstrates the alternation of generations with haploid gametophyte and diploid sporophyte alternation. The sporophyte stage is the primary period of an angiosperm’s life cycle. Angiosperms are heterosporous. This means they produce bigger megaspores and smaller microspores.

Detailed explanation-3: -Flowering plants, also called angiosperms, use a sexual mode of reproduction. Reproduction in plants, mainly revolves around the flower, which has both the male and the female gametes. All parts of a flower aid in the process of reproduction, although some of them are sterile.

Detailed explanation-4: -Gymnosperms are mainly conifers, such as pine and fir trees. They produce both male and female cones.
