Detailed explanation-1: -Flowering plants (angiosperms) are by far the largest, most diverse, and most important group of land plants, with over 250, 000 species and a dominating presence in most terrestrial ecosystems. Understanding the origin and early diversification of angiosperms has posed a long-standing botanical challenge [1].

Detailed explanation-2: -Angiosperms are plants that produce flowers and bear their seeds in fruits. They are the largest and most diverse group within the kingdom Plantae, with about 300, 000 species. Angiosperms represent approximately 80 percent of all known living green plants.

Detailed explanation-3: -Orchidaceae. The Orchidaceae is the largest plant family with approximately 28, 000 species (Christenhusz and Byng, 2016).

Detailed explanation-4: -Angiosperms are the largest plant group because it this the most evolutionarily developed and adapted group. They hide and protect their seeds in fruits, this also allows them to spread.

Detailed explanation-5: -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.
