DENDROLOGY

Detailed explanation-1: -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-2: -Seeds are surrounded by one or two integuments, which develop into a seed coat that is usually hard. They are enclosed in the ovary of a carpel and thus are protected from the elements and predators. The ovule is attached to the ovary wall until maturity by a short stalk called the funiculus.

Detailed explanation-3: -This group is usually referred to as angiosperms because, as their name implies, their seeds are enclosed in a carpel (in a vessel). The carpel is the primary feature that distinguishes angiosperms from gymnosperms. Angiosperms live in all terrestrial and aquatic habitats on earth.
