Phloem transport/loading Outline of Current Lecture I. Evolutionary changes of plant ReproductionII. Flower PartsCurrent LectureI. Evolutionary Changes in Plant Reproduction-a. During evolution of land plants, the sporophyte gets larger and more complexb. The gametophyte becomes smaller and less complexc. With moss, the sporophyte is small and dependent on the gametophyted. In flowering plants the sporophyte is larger and independent of the gametophyteII. Flowering Parts-a. Sepals- protects unopened flower budb. Petals- attract pollinatorsc. Stamen- produce male gametophytes and foster their early developmenti. produce male haploid spores through meiosisii. anther- on top of the filament, a group of four sporangia that produce sporesiii. filament- an elongated stalk that delivers nutrients to the antherd. carpels- produce and nurture female gametophytesi. vase shaped structuresThese notes represent a detailed interpretation of the professor’s lecture.
