Which type of plant is most closely related to flowering plants? CONIFERS HISTORY OF CLASSIFICATION SYSTEMS o Aristotle – Plants and Animals o Linneaus – developed BINOMIAL NOMENCLATURE o TWO KINGDOMS: plants and animals o THREE kingdoms: plant, animal, Protist o FIVE kingdoms: plant, animal, Protist, fungi, Moneran CLASSIFICATION K •Kingdom P •Phylum C •Class O •Order F •Family G •Genus S •Species Scientific name is genus and species name. Organisms in same genus are closely related FIVE KINGDOM CLASSIFICATION Moneran Protist Fungi Plant Animal •Bacteria •Prokaryotic •No nucleus •Have cell wall •Unicellular •Can be heterotrophic or autotrophic •Protozoans, algae •Eukaryotic •Have nucleus • Some have cell wall •Mainly unicellular •Can be heterotrophic or autotrophic •Mushroom, yeast •Eukaryotic •Have nucleus •Have cell wall •Mainly multicellular •heterotrophic •Moss, fern, trees, flowers •Eukaryotic •Have nucleus •Have cell wall •All multicellular •autotrophic •Sponge, annelids, amphibians, birds, mammals •Eukaryotic •Have nucleus •No cell wall •All multicellular •heterotrophic DICHOTOMOUS KEY • • • • Always begin with #1 Follow directions using choices given What shape is “Gina”? Equilateral triangle TYPES OF PLANTS Bryophytes Gymnosperms Angiosperms •Non-vascular •No xylem or phloem •Examples are mosses •They are small •Have to be near water •No pollen, seeds, flowers, or fruits •Vascular •Xylem to move water •Phloem to move food •Examples are conifers •Have pollen (sperm) •Have seeds on cones •No fruits or flowers •Vascular •Xylem to move water •Phloem to move food •Examples are flowering plants like oak trees, corn, and roses •Have pollen (sperm) •Have seeds in fruits •Have flowers PLANT ADAPTATIONS ROOT, STEM, LEAF Roots are adapted to absorb water with root hairs Leaves are adapted for photosynthesis by being flat and green Stems move water with xylem FLOWERS AND FRUITS Flowers have bright petals to attract pollinators Pollen (Sperm) can be transferred by animals When egg joins with pollen, a seed is formed in the ovary The ovary becomes the fruit Fruit surrounds and protects seed Fruit also helps get baby plants in seeds away from parent plant TYPES OF ANIMALS Annelids Insects Amphibians Mammals •Segmented worms •No backbone •“breathe” through skin •Closed circulatory system •External fertilization •External development •No backbome •Three body segments •Six legs •Wings •Open circulatory system •External fertilization •Females may store sperm •External development •metamorphosis •Have backbone •Moist skin •Gills when young, lungs when adult •Three chambered heart •Cold-blooded •External fertilization •External development •Metamorphosils •Jelly like egg •Backbone •Hair •Milk glands •Lungs •Four chambered heart •Warm-blooded •Internal fertilization •Internal development •Amniote egg
