Flower Shoot System 1 (outer part of a flower) 2 green, protective 3 colored, attractant 4 male part 5 female part	. 1 Perianth 2 Calyx (sepals) 3 Corolla (petals) 4 Stamens 5 Carpels
Plants which produce flowers Most important economically!	Angiospermae (angiosperms)
Why have Angiosperms been so successful?	Flowering plants Most abundant of plants Reproduce by seeds or pollination Contain fruit
Angiosperm largest plant families	1 Orchids (Orchidaceae) 2 Compositae (daisies) 3 Legumes (beans)
Class Dicots subclass consisting of those families of dicots that lack petals or have petals separate from each other.	Archichlamydeae
1 Mainly tropical twining shrubs, herbs or trees Contains alkaloids (diterpene,triterpene) Saponins 2 Second largest family of flowering plants Contains alkaloids, cyanogenic glycosides Saponins, tannins Mucilage, anthrocyanins	1 Menispermaceae 2 Leguminosae
Most members are trees or shrubs. Flowers are unisexual and regular, fruit is three-celled capsule. Many species have latex, some are poisonous and irritant Contains cyanogenic glycosides, fixed oils Anthraquinones, triterpenoids Alkaloids (aporphine, pyridine, quinoline, tropane)	Euphorbiaceae
Mainly shrubs or trees. Oil glands are of general occurrence. Contains alkaloids, volatile oils, rhamnoglucosides, coumarins,terpenoids Alkaloids include amine, imidazole, indole,pyridine, pyrrolidine Fruits are rich in vit.C and citric acid	Rutaceae (citrus family)
Members are herbs with furrowed stems and hollow internodes Large leaves sheathing base and much divided lamina Flowers are small in simple or compound umbels Contains vol oils,resins, coumarins, terpenes, acetylenic compds	Umbelliferae
Leguminosae subfamily	1 Mimosaceae 2 Caesalpiniaceae 3 Papilionaceae
Class Dicots Subclass Derived their name from the fact that their petals are joined together	Sympetalae
