Transcript of Biology 11U

Diversity of Life classification created by Carolus Linnaeus considered to be the father of Taxonomy can be represented by Phylogenetic Tree categories used to classify organism taxons categories species example Homo sapiens genus example Apis family example Hominidae rank #5 rank #7 rank #6 class rank #3 Order rank #4 Kingdom Phylum rank #1 rank #2 example example Aves Carnivora prokaryotic archea Archaebacteria Kingdom Human Influence how we are influenced decomposers vitamins Subgroups heat-loving Extreme
Thermophiles cold-loving Extreme
Psychrophiles live in saline environments Extreme
Halophiles low oxygen environment Methanogens prokaryotic eubacteria Eubacteria Kingdom Human Influence how we are influenced decomposers Infestation Diseases such as how we influence Antibiotics such as Commercial Use such as Arrangements round Cocci type of cells cluster single staphylococcus coccus pair linear diplococcus streptococcus rod-shaped Bacilli single pair linear bacillus diplobacillius streptobacillius spiral or corkcrew Spirillia single spirillium eukaryotic
organisms Kingdom Animalia Invertebrates Phylum
Porifera such as Sponges Phylum
Cnidaria such as Jellyfish coral sea anemone Vertebrates Phylum
Platyhelminthes such as tapeworms Phylum
Rotifera Phylum
Nematoda Phylum
Annelida Phylum
Mollusca Phylum
Athropoda such as such as such as snails squids earthworms leeches subgroups Arachnids such as scorpians Insects Crustaceans such as such as crabs butterflies Phylum
Echinodemata such as starfish sea urchins Phylum
Chordata classes
included Aves Amphibia such as Reptilia frogs like snakes lizards turtles Jawless
Fishes (birds) Cartilaginous Fishes Bony Fishes such as lamprey like salmon tuna such as sharks rays Mammalia sub-groups Monotremes Marsupials Placental (eutherians) such as platypus echidnas like kangaroos koalas opossums like sloths humans cats Human Influence how we are influenced how we influence food hunting and fishing urbanization and deforestation meat and fish have become largely consumed products species extinction species extinction and habitat destruction eukaryotic
organisms Kingdom Plantae Fungi Kingdom Kindgom Protista Vascular Non-vascular Bryophytes division mosses protection for embryo Spores adaptive vascular system Seeds asexual reproduction Seedless
Vascular examples Ferns Horsetails flowering conifers Gymnosperms examples Spruce Redwoods Angiosperms Dicot Monocot examples Apple Trees violets roses fruit baring examples wheat Sugarcane bamboo Human Influence how we are influenced how we influence paper products such as clothing wood used for building, heating, furniture, etc. Pollution Food Source plant and harvest crops species is threatened offspring feed from nipples in pouch egg-laying pouched true placenta a nutrients & waste filter eukaryotic
organisms first eukaryotic organisms Major Phyla
Fungi Chytrids Batrachochytrium dendrobatidis example most primitive
of fungi -most are soil fungi
-sexual reproduction Zygomycetes examples Rhizopus oryzae
(used to make Asian rice wine) Rhizopus stolonifera
(Bread Mold) -useful to humans
-cause serious plant diseases Ascomycetes example yeast -forms symbiotic relationships
with plant roots
-reproduce asexually Glomeromycetes examples Glomus mossae -most are decomposers
-forms symbiotic relationships
with plant roots Basidiomycetes examples mushrooms puffballs Human Influence how we are influenced Antibiotics such as penicillin Fermentation such as -Fungus is used to make bread and alcohol
-Fungus ferments grains and grapes Human Influence Main Groups -Absorptive
-reproduce asexually
and sexually -Ingestive
-reproduce asexually
by binary fission
-heterotrophic -Photosynthetic
-produce asexually by mitosis
-autotrophic Fungus-like which are decomposers such as slime molds water molds Animal-like Plant-like also called protozoa include phyla Zoomastigina includes which move by flagella Giardia Sarcodina includes which move by ameoba pseudopodia Ciliophora Sporozoa includes includes which move by which causes cilia paramecium plasmodium which does not move also called can be Algae multicelluar unicelluar such as such as brown algae green algae red algae Euglena diatoms includes includes includes kelp spirogyra chondrus how we influence how we are influenced Pollution Photosynthesis Sickness pollutes their environment,
may cause extinction photosynthesis of many protists
produce atmospheric oxygen cause sickness such as malaria,
sleeping sickness, etc.
