Title: Characteristics of Living Things and Classification


1
Characteristics of Living Things and
Classification
  • What makes something living?
  • How do we organize living things?

2
Biology
  • Bio- life
  • Ology- study of

What are they looking at?
3
BIOLOGY THE STUDY OF LIFE.
  • ALIVE OR NOT ALIVE????
  • Scientists have not really decided upon a single
    definition of life, but it is determined by the
    actions of life functions carried on by an
    organism.

I. Organization of Living Things
MULTICELLULAR ORGANISMS
COMPLEX
UNICELLULAR ORGANISMS
SIMPLE
5
II. 4 Characteristics of ALL Living Things
  1. Living things are made of CELLS that contain DNA
  2. Living things have a METABOLISM to help them use
    ENERGY to live, grow, and develop
  3. Living things maintain HOMEOSTASIS (a stable
    internal environment)
  4. Living things REPRODUCE

6
Characteristics of Living Things(531)

III. Similarities and Differences Among Living
Things
  • Living things go about the 4 characteristics in
    similar AND different ways
  • 8 Life processes that are similar and different
    among living things
  • Obtaining nutrients
  • Transport of materials throughout organism
  • Breaking down nutrients to get energy (cellular
    respiration)
  • Combining simple substances to make more complex
    substances (synthesis)
  • Growth
  • Removal of waste products (Excretion)
  • Responding to internal and external stimuli
  • Reproducing

8
Simple to Complex (153)

IV. Helping Vocabulary
  • Number of cells
  • Multicellular
  • Made of many cells
  • Examples Plant, Animals
  • Unicellular
  • Made of one cell
  • ex. Bacteria, Paramecium, Ameba, Euglena, Yeast

Copy down all of the examples
10
  • B. Nucleus?
  • Eukaryote
  • Cells contain a nucleus
  • Prokaryote
  • Cells lack a nucleus
  • C. Mode of nutrition
  • Heterotroph
  • Need to obtain food ex. humans
  • Autotroph
  • Can make their own food by a process called
    photosynthesis ex. plants

11
The Five Kingdoms (352)

(No Transcript)
13
The 5 Kingdoms
  • Similarities and Differences in life processes
    has grouped organisms into 5 different kingdoms
  • Animalia
  • Fungi
  • Plantae
  • Protista
  • Monera

MULTICELLULAR
EUKARYOTIC
UNICELLULAR
PROKARYOTIC
14
V. Obtaining Nutrients (FOOD!?)
  • Heterotroph
  • Gets nutrients from the environment
  • Kingdoms
  • Animalia, Fungi, Some Protista and Monera
  • Autotroph
  • Makes own food
  • Kingdoms
  • Plantae and some Protists (photosynthesis), some
    Bacteria (chemosynthesis)

15
Quiz Time
  1. What does prokaryote mean?
  2. Give an example of a prokaryote.
  3. What does autotroph mean?
  4. Give an example of an autotroph.
  5. Name 3 of the 5 Kingdoms.
  6. What does the nucleus of a cell hold?

16
VII. Transport of materials
  • Unicellular Orgs
  • Transport within cytoplasm
  • Kingdoms
  • Protista, Monera
  • Multicellular Orgs
  • Transport within liquids and tubes
  • Kingdoms
  • Animalia, Plantae, Fungi

17
VIII. Reproduction
  • Asexual
  • One parent
  • Offspring genetically identical (clones)
  • Kingdoms
  • Some Fungi, Protista, Monera
  • Sexual
  • Two parents
  • Offspring genetically different from parents
  • Kingdoms
  • Some Fungi, Plantae, Animalia

18
IX Classification of Living Things
  • Why classify organisms?
  • For easy identification
  • For evolutionary comparison of organisms
  • Organisms are grouped into large categories based
    on similarities
  • Once in a group, organisms are separated based on
    differences

Modern Classification System classify from
broad to specific
19
Classification of Living Things
  • 5 Kingdoms
  • Phyla (s. Phylum)
  • Class
  • Order
  • Family
  • Genus
  • Species

DIVIDED INTO
DIVIDED INTO
DIVIDED INTO
OF ORGANISMS DECREASES
DIFFERENCES AMONG ORGS INCREASES
DIVIDED INTO
DIVIDED INTO
DIVIDED INTO
20
Acronym to help remember!
  • King
  • Phillip
  • Called
  • Oprah
  • For
  • Good
  • Spices

21
Classification of Humans
  • KINGDOM Animalia
  • PHYLUM Chordata
  • Has backbone
  • CLASS Mammalia
  • Females have mammary glands
  • ORDER Primates
  • Larger brain size
  • FAMILY Hominidae
  • GENUS Homo
  • SPECIES sapiens

22
Scientific Naming
  • Referred to as Binomial Nomenclature (2 name
    naming system)
  • Scientific name Genus species
  • species is not capitalized
  • Both are always italicized or underlined
  • Ex. Homo sapiens or Homo sapiens
  • Abbreviation
  • First letter of genus (capitalized), followed by
    species
  • Ex. H. sapiens
  • Scientists have only identified and named a
    FRACTION of all living organisms on Earth!!!!
