Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (/ ˌ æ n dʒ i ə ˈ s p ər m iː /). [ 5 ] [ 6 ] The term 'angiosperm' is derived from the Greek words ἀγγεῖον / angeion ('container, vessel') and σπέρμα / sperma ('seed'), meaning that the seeds are enclosed within a fruit.
Fruit is produced after 4 years and is red or sometimes yellow, measuring between 20 and 25 mm across. A 3-mm layer of flesh covers a brain-like nut with a hard shell that encases the seed. This fruit is referred to as a drupe. It ripens from green to a shiny red in late spring or summer, and is globe-shaped and 20 to 40 mm across.
For example, the young leaves can be cooked and eaten. The raw seeds are toxic, but may be eaten when cooked. [6] In Singapore, the species forms part of the diet of local Raffles' banded langurs. [7] Adenanthera pavonina seeds have long been a symbol of love in China, and its name in Chinese is xiang si dou (Chinese: 相思豆), or
Angiosperm seeds are "enclosed seeds", produced in a hard or fleshy structure called a fruit that encloses them for protection. Some fruits have layers of both hard and fleshy material. In gymnosperms, no special structure develops to enclose the seeds, which begin their development "naked" on the bracts of cones.
angiosperm A flowering plant; a plant with developing seeds enclosed in an ovary. anisomery The condition of having a floral whorl with a different (usually smaller) number of parts from the other floral whorls. anisotomic Branching, with branches having unequal diameters, such as a trunk and its branch. Contrast isotomic. annual
Fruits are the mature ovary of seed-bearing plants, and they include the contents of the ovary, which can be floral parts like the receptacle, involucre, calyx, and others that are fused to it. Fruits are often used to identify plant taxa, help to place the species in the correct family, or differentiate different groups within the same family.
Seed plants include two clades with living members, the gymnosperms and the angiosperms or flowering plants. In gymnosperms, the ovules or seeds are not further enclosed. In angiosperms, they are enclosed within the carpel. Angiosperms typically also have other, secondary structures, such as petals, which together form a flower.
Angiosperms, the flowering plants, possess seeds enclosed in a fruit, unlike gymnosperms. In addition to the five living taxa listed above, the fossil record contains evidence of many extinct taxa of seed plants, among those:
