NEET BIOLOGY

Detailed explanation-1: -Angiosperm. The most diversified phylum is Angiosperms that contains 260, 000 flowering vascular plant species.

Detailed explanation-2: -The largest group of living seedless vascular plants-and probably the most familiar-are the ferns with about 12, 000 species, over two‐thirds of which are tropical. Ferns are an ancient group.

Detailed explanation-3: -Plants are broken down into two main groups. They are either vascular or nonvascular. VASCULAR PLANTS make up about 80% of all plants. They have special tissues in their stems to move water and nutrients up and down the plant (xylem and phloem).

Detailed explanation-4: -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-5: -Nonvascular plants (often referred to collectively as the bryophytes) include three groups: the mosses (Bryophyta), approximately 15, 000 species; liverworts (Hepaticophyta), approximately 7500 species; and hornworts (Anthocerophyta), approximately 250 species (Table 1).
