Kingdom Plante Outline

Chapter 27 - Kingdom Plantae 1) Discuss the human uses and the adaptations of gymnosperms. 2) Contrast dicots with monocots, and describe the life cycle of flowering plants. 3)Compare the various plant life cycles, and explain why angiosperms are more diverse and widespread than the other plant groups. 4) Discuss the human uses and the adaptations of flowering plants. gymnosperm - a vascular plant producing naked seeds, as in conifers. [gymn - naked,sperm - seed]dicotyledons (dicots) - woody or herbaceous and they have flower parts usually in foursand five’s, net-veined leaves, vascular bundles arranged in a circle within thestem, two seed leaves. [di - two, kotyl - cavity]monocotyledons (monocots) - herbaceous and have flower parts in threes,parallel-veined leaves, scattered vascular bundles in the stem, and one seed leaf.[mono - one, kotyl - cavity]angiosperm - a flowering plant, the seeds are borne within a fruit. [ang - vessel, sperm -seed]1a) Uses of Gymnosperms- Supply much of the wood used for building and paper production.- They produce valuable chemicals1b) Adaptation of the Gymnosperms- Well developed roots and stems- Pollen grains are transferred by wind - No need for to water to fertilize.2) Contrast dicots and monocots- See definitions3a) Compare various plant life cycles- Nonvascular Plants* Dominant gametophyte* Flagellated sperm* Dependent sprorophyte* Homospores disperse the species- Seedless Vascular Plants* Dominant sporophyte* Homospores disperse the species* Independent gametophyte* Flagellated sperm- Seed vascular plants* Dominant sporophyte* Heterosporous* Dependent micro-, macrogametophytes* Pollen grains* Seeds disperse the species3b) Why angiosperms are more diverse and widespread than the other plant groups.- The fruit they produce gives a better covering for the seed to mature- Animals eat the fruit then deficate somewhere else whichtransports the seeds.4a) Human uses of flowering plants- food- oil...
