Characteristics of an angiosperm - Have flowers, produce fruit and seeds, have ovules enclosed by an ovary Angiosperm origins - - descended from gymnosperms - arose during cretaceous period Angiosperm habitats - - majority are terrestrial, some aquatic - some, such as the Xerophytes are specialized for super dry places - some, such as the Halophytes specialize in withstanding high salt levels

To adapt to dry and cool conditions - Why are leaves of conifers long and thin (pine needles) Specialized tissue to conduct water and nutrients - What is vascular tissue Substance in cells that makes cell walls rigid. Enables vascular plants to grow upright - What is lignin
