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: -Unlike gymnosperms such as conifers and cycads, angiosperm’s seeds are found in a flower. Angiosperm eggs are fertilized and develop into a seed in an ovary that is usually in a flower. The flowers of angiosperms have male or female reproductive organs.
Detailed explanation-3: -The stamens produce the male gametes in pollen grains. The carpels contain the female gametes (the eggs inside the ovules), which are within the ovary of a carpel. The walls of the ovary thicken after fertilization, ripening into fruit that ensures dispersal by wind, water, or animals.
Detailed explanation-4: -The fruit is formed after fertilization from the ovary and the ovules get converted to seeds. After fertilization, the flower whorls withers, and all the reproductive structures fall off. The embryo is within the ovule which ovule transforms into a seed with a hard covering to protect the growing embryo.
