Explain why Darwin called the origin of angiosperms an “abominablemystery,” and describe what has been learned from fossil evidenceand phylogenetic analyses.
Describe what the early angiosperm may have been like with regard to flowers, body, ecołogy, wood and pollen. For each of the characters, what living angiosperms still have those characters? In what ways have those changed in certain lines of evolution?
Describe the orders ANGIOSPERMS-EUDICOTS : ERICALES, GENTIANALES, LAMIALES, SOLANALES, APIALES AND ASTERALES in terms of plant habit, reproductive type (monoecius/dioecius), leaf type, leaf shape, floral characteristics, fruit morphology, seed size/shape, and other distinct features.
