BIO 3102 Study Guide - Microsporangia, Cenozoic, Synapsid
Document Summary
Recovery, continental breakup, flower power, and the age of reptiles. Amniote animals: an animal whose embryo develops in an amnion and chorion and has an allantois; a mammal, bird, or reptile. Important to realize that the water proof egg with nutrient reservoir, wastes sac, and floating embryo in aquatic environment have a distinct advantage to this group no predators to the young. Anapsid: have no temporal arches and no spaces on the sides of the skill. Turtles are living representation of this group (although they actually come from the diapsid lineage) Angiosperm: flowering plants which are the most successful. Defining features include carpel and fruit which help protect and disperse seeds. As with other seed plants the large diploid sporophyte phase dominates a flowering plant"s life cycle, and the sporophyte retains and nourishes the smaller gametophytes. Meiosis produces four megaspores, then all but one disintegrate.
