1 9 Weeks Test Review

2 Aristotle--- was the first to place living things into categories according to where they lived and if they had “blood”

3 LINNAEUS Linnaeus--- the “Father of Taxonomy” He came up with the two word naming system called binomial nomenclature

4 BINOMIAL NOMENCLATURE Binomial nomenclature---the two word naming system (Genus species)

5 TAXONOMY Taxonomy – the science of how living things are classified

6 YOU What is your scientific name? Homo sapiens What does it consist of? Genus and species How to write it correctly?Homo sapiens

7 LEVELS List the major levels of classification from highest/broadest to lowest/most specific Domain-Kingdom- Phylum-Class- Order-Family- Genus-Species Dumb king phillip chased old fat girl scouts

8 DOMAINS 3 Domains and characteristics of each 1Archaea – unicellular organisms that can live in harsh conditions; Prokaryotes 2Bacteria – unicellular organisms that are also Prokaryotes 3Eukarya – unicellular and multicellular Eukryotes

9 ANIMALS Characteristics of the animal kingdom – Animals are multicellular – many cells, heterotrophic (eat food), eukaryotes (have a nucleus)

10 HYPOTHESIS Hypothesis – a possible explanation for a set of observations or answer to a scientific question Will more chocolate chips make cookies taste better?

11 Experiments Controlled experiment - An experiment in which only one variable is manipulated at a time

12 Controlled Variable. Controlled Variable – the variables that are not changed in an experiment

13 Operational Variable Operational Variable – how to measure a variable or define a term.

14 Manipulated or Independent Variable 3. Manipulated Variable – the only variable that is changed in an experiment – ex – chocolate chips!

15 Responding Variable Responding Variable – the factor that may change as a result of the manipulated variable EX - TASTE

16 CLASSIFYING Classifying – placing into groups based on criteria

17 Observing Observation – using your senses

18 Types of Observations Quantitative vs. qualitative observations – numbers vs no numbers

19 THE ODDS & ENDS KINGDOM Cilia---Hairlike structures Used for movement/locomotion by some bacteria and protists

20 Pseudopods Pseudo pods---false feet Used for movement/locomotion by Amoebas

21 Flagella Flagellum--- long whip like structures Used for movement by Euglena

22 DNA What is found in nucleus of cell? DNA – the genetic material Where is genetic material of a bacteria cell found? Loose in the cytoplasm

23 Virus 5. Draw and label the structure of a virus

24 How Viruses Multiply Active viruses enter cells and immediately begin to multiply, leading to the quick death of the invaded cells. - Viruses

25 Virus How are viruses like parasites?they harm the host

26 Bacteria Shapes Shapes of Bacteria--- spirilla (spiral), Cocci (spherical), and Bacilli (rod- shaped)

27 Sexual Reproduction Draw and explain conjugation Sexual reproduction in which genetic material is exchanged between 2 parents. The offspring is more genetically different than those produced by binary fission

28 Asexual Reproduction Binary Fission Asexual reproduction in which a cell splits and the offspring is identical to the parent

29 Eukaryotic cells Animal Cells are which type? Eukaryotic cells What is their outer covering?cell membrane

30 PRODUCER Producer – An organism that is at the base of the food chain that makes their own food. THE PRODUCERS HAVE THE MOST ENERGY IN THE FOOD PYRAMID AND WEB!

31 Consumers Consumer – An organism that cannot make their own food and must eat producers or other consumers

32 Definitions Prokaryotes – no true nucleus Eukaryotes – have a nucleus Autotrophs – make their food (producers) Heterotrophs – eat food (consumers

33 Food Chain Food Chain – shows the simple feeding relationship in a ecosystem

34 Food Web Food Web – the pattern of overlapping food chains in an ecosystem

35 Energy Pyramid Energy Pyramid – a diagram that shows how energy moves from one feeding level to another in a food web

36 Biology Biology – The study of living things

37 CELLS Unicellular – one cell Multicellular – many cells

38 Limiting Factor Limiting Factor any environmental factor that causes a population to decrease Examplesfood, water, living space, weather

39 Biotic/Abiotic Biotic factor – living things in the ecosystem Examples animals, plants Abiotic factor – nonliving part of an ecosystme Examples rocks, water, sunlight

40 Levels of Organization Organism – one individual – ex one prairie dog Population – the same species ex – all the prairie dogs in an area Community – all the populations - ex – all the dogs, rabbits, owls, etc Ecosystem – all the biotic and abiotic parts ex – animals, plants, weather, sunlight, rain, soil ex – desert ecosystem

41 Methods of Estimating Populations Direct Observation – counting

42 Indirect Observation Indirect observation –counting nests or tracks

43 Sampling Sampling - counting a small area and multiplying to get the large area

44 Mark & Recapture Mark & Recapture – catching and marking and releasing and recatching

45 Consumers Carnivore – meat eater Herbivore plant eater Omnivore eats plants and animals

46 Chloroplasts in Plant Cells Where does photosynthesis take place? In plant cells – in the chloroplasts What is the name of the green pigment?chlorophyll

47 Plant Types Vascular vs. non- vascular plants Vascular plants have a tube like system for transporting materials and nonvascular do not.

48 PHLOEM The tube in a vascular plant used for transporting food

49 Xylem The tube in a vascular plant that is used for the transporting of water and minerals.

50 Stop! Dormancy – a period when an organisms growth or activity stops

51 Germination When a plant begins to push out of the seed and grow

52

53 Water Cycle

54 Nitrogen Cycle

55 Carbon Cycle

56 Parts of a SEED

57 Fruit The ripened ovary

58 POLLEN Pollen is produced by seed plants and will later become sperm cells

59 Seed Dispersal By wind By Water By organisms
