Document Summary
Conifers: male cones are simple cones" axes bores microsporophyll"s. Douglas fir cones have three lobed bracts with scales. Seed scale is the same location as bud. Telome theory (robert zimmermann) explains how you got from earliest land plants (simple branch with terminal sporangia) to a typical land plant with has axes that bare planar leaves with venation. Strobiloid flowers the way of two types of pollen. Gradual transition of leafy structures to sepals and pedals at base and stamens and pistils near the tip. Gametophyte: genetic incompatibility with building on race through style. Sporophyte: compounds are in conflict with stigma and won"t germinate because of locus of a few alleles. Androecium: stamens are the male function-send pollen to other flowers. Have stock/filament and anthers (typically 2), which are microsporangia (bare microspores). Reduces stamens on perfect flowers are called staminodes. Corolla and calyx forms the periamth: sometimes cannot be differentiated and then called tepals.
