Plant Diversity
Question | Answer |
---|---|
four phyla of the plant kingdom | Bryophytes, Pteridophytes, Gymnosperm, Angiosperm |
adaptions of land plants significant for survival | protection from drying, gas exchange, waste and nutrient conducting system, and protection for embryo |
Bryophytes | non-vascular, swimming sperm, spores for reprodction |
dominant phase of the moss life cycle | haploid gametophyte stage |
adaptations of Pteridophytes not seen in Bryophytes | vascular, life cycle dominated by the sphoryte stage |
dominant stage of the fern life cycle | sporophyte stage |
significance of the seed | protection for the embryo, stored nutrients for growth of embryo, and adaption for reproduction in diverse terrestrial environments |
advantage of pollen | eliminated the requirement for water fertilization |
four phyla of gymnosperms | ginkgo, cycads, conifers, and cones and naked seeds |
adaptive value of the flower to plants | flowers are just plants that have petals, stomatans, carpels, and embrroy |
