HORTICULTURE

Detailed explanation-1: -The first step was the development of mosses, followed by vascular plants ferns (and fern allies such as Lycopodium spp.). The next evolutionary step that took place was the development of cone-bearing plants (gymnosperms), and finally, flowering plants (angiosperms).

Detailed explanation-2: -Four major adaptations are found in all terrestrial plants: the alternation of generations, a sporangium in which the spores are formed, a gametangium that produces haploid cells, and apical meristem tissue in roots and shoots.

Detailed explanation-3: -Vascular plants like ferns and horsetails don’t have seeds, they reproduce with spores! These plants have two stages, the gametophyte stage and the sporophyte stage.

Detailed explanation-4: -1 Colonization of land. 2 Evolution of life cycles. 3 Evolution of plant anatomy. 3.1 Arbuscular mycorrhizal symbiosis. 4 Evolution of plant morphology. 5 Evolution of photosynthetic pathways. 6 Evolution of transcriptional regulation. 7 Evolution of secondary metabolism. 8 Evolution of plant-microbe interactions.
