LD Biology Chapter 7
| Term | Definition |
|---|---|
| TAXONOMY | Science of naming and classifying organisms |
| SPECIES | A population of organisms of the same kind that can mate and produce fertile offspring. |
| EVOLUTION | Species gradually change over long periods of time to produce new species. |
| CLASSIFICATION CATEGORIES | Kingdom, Phylum, Class, Order, Family, Genus, Species |
| BINOMIAL NOMENCLATURE | Genus, Species (Ex: Homo sapiens, Felis domesticus, Canis familiaris) |
| WHO NAMED ALL THE PLANTS AND ANIMALS IN 1753? | Linnaeus |
| PHYLOGENETIC TREE | Shows common ancestry |
| EVIDENCES OF EVOLUTION | Structural, Biochemical, Cytology, Embryological, Behavior, and Fossils |
| STRUCTURAL INFORMATION | Similar skeletal or anatomy |
| BIOCHEMICAL INFORMATION | DNA, RNA, & Proteins may have similar chemical reactions in organisms. |
| CYTOLOGY INFORMATION | Similar cell structure |
| EMBRYOLOGICAL INFORMATION | Similar stages of development in embryos |
| BEHAVIOR INFORMATION | Mating habits could differ in species |
| FOSSIL INFORMATION | Show relationships in bones, footprints, or impressions. |
| SIX KINGDOMS | Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia |
| MONERANS | Unicellular, lack of nuclear membrane "prokaryotic" |
| ARCHAEBACTERIA | Live in harsh environments, lack carbohydrate "peptidoglycan in their cell walls." |
| EUBACTERIA | Have Peptidoglycan in cell walls. |
| PROTISTA | Have membrane bound nucleus & other organelles "eukaryotic" |
| PROTOZOA | Animal like - heterotrophic |
| ALGAE | Plant like, autotrophic due to photosynthesis |
| FUNGI | Heterotrophs: live as parasites or as decomposers of dead matter. Secrete enzymes that digest food materials then they absorb the nutrients (ex: mushrooms) |
| ANIMALIA | Heterotrophic (Invertebrates - no backbone / Vertebrates - backbone) |
| PLANTAE | Autotrophic (make their own food via photosynthesis) |
| BRYOPHYTES | No vascular tissue - Ex: Moss |
| TRACHEOPHYTES | Vascular Tissue (xylem & phloem) - Ex: Trees |
| DICHOTEMOUS KEY | Used to classify |
| REPRESENTATIVE ORGANISMS | Ameba, Paramecium, Hydra, Earthworm, Grasshopper, Human |
| AMEBA | Moves as cytoplasm fills their "pseudopods" or false feet. They engulf their food by phagocytosis |
| PARAMECIUM | Move by hairlike structures called cilia, has 2 nuclei (a micronucleus and micronucleus). Also, has an oral groove to take in food. |
| HYDRA | Belongs to phylum Cnidaria - 2 cell layers thick, hoolwo body with 1 opening. |
| EARTHWORM | Phylum Annelida - has well developed digestive, circulatory, excretory, and nervous system. |
| GRASSHOPPER | Anthropoda "jointed feet" has well developed digestive, circulatory, respiratory, excretory, and nervous system. |
| HUMAN | Phylum Chordata - a dorsal hollow nerve cord (spinal cord), a notochord-flexible, rodlike internal supporting structure (backbone), gill slits possibly during embryo stage. Mammals nourish young with milk, have hair or fur, & well developed brains. |
