Title: Classification of living things


1
  • Classification of living things

2
Organism or Not Organism
Organism Not Organism

3
What is an organism?
  • An organism is a living thing.
  • How do we know something is a living thing?
  • With your partner, write down characteristics of
    living things.

4

Characteristics of Living Things
2. reproduce
1. obtain and use resources

3. grow and develop
4. respond to stimulus
growth development
5
What do you think?
  • 1. What is an organism?
  • 2. How can you tell if something is an organism?

All Living things must1. obtain and use
resources for energy
  • They must obtain (get) food, oxygen, and water to
    grow, develop and repair themselves.

9
Organisms are either
  • 1. Autotrophs organisms that make their own
    food. For example plants.
  • Or
  • 2. Hetertrophs organisms that do not make their
    own food. For example animals.

10
2. respond to stimuli
  • A stimulus is any change in a living things
    environment. Some stimuli come from the
    enviroment, while some come from inside the
    organism.
  • A reaction to the stimulus is response.This is
    any action or behavior performed by the organism.

11
Match the stimulus and response
  • Stimulus
  • Bright light
  • Loud sound
  • Fear
  • Hunger
  • Change in temperature
  • Response
  • Shed winter fur
  • Close eyes
  • Faster heart beat
  • Hunt
  • jump

12
3. reproduce
  • Organisms produce offspring that have similar
    characteristics as the parent. There are two
    ways to reproduce
  • Asexually - involves only one parent. The
    offspring are identical to the parent.
  • Sexually - involves two parents that produce
    offspring that have characteristics from each
    parent.

13
4. grow and develop
  • Growth and development is not the same!
  • Growth When an organisms becomes larger.
  • Development When an organism becomes more
    complex structurally.

14
Growth or Development?You decide
  • 1. An egg becoming a baby chick.
  • A small plant becoming a larger plant.
  • A tadpole to frog.
  • A baby gaining five ounces in a week
  • The baby learned to roll over
  • The baby had longer hair in a year

What I Think
  • Divide these pictures into groups
  • Give each group a name and tell why you put the
    pictures together

19
Classification of Living Things
  • 3. Classification is the process that scientists
    use to arrange organisms into groups based on the
    shared observable characteristics.

20
Classification of Living Things
  • 4. Taxonomy is the science of identifying and
    classifying organisms into groups.

21
Characteristics of Living Things
  • Continued from previous slide
  • A taxonomist is a scientist who identifies and
    names organisms based on their similarities and
    differences.
  • Taxonomist use physical characteristics as well
    as DNA, genetic information, to classify
    organisms.

22
Characteristics of Living Things
  • Scientist all over the world study organisms, in
    order to avoid confusion scientists need a
    universal way of naming organisms.

24
Characteristics of Living Things
  • 6. A dichotomous key is a tool used to identify
    organisms. It uses a series of questions, each
    with only 2 answers.

25
Characteristics of Living Things
  • The scientific name is made up of the genus and
    species of the organism.
  • The name is written in italics, the GENUS is
    capitalized, and the species is lower case
  • for example the scientific name for a human is
    Homo sapiens because homo is our genus and
    sapiens is our species.

26
Characteristics of Living Things
  • The Linnaeus system is made up of seven levels,
    Kingdom, Phylum, Class, Order, Family, Genus, and
    Species.
  • King Philip Could Only Find Green Socks is one
    mnemonic way to remember the order of the levels.
    Another is King Philip Came Over For Good
    Spaghetti.
  • The levels are arranged from the most broad,
    Kingdom, to the most specific, Species.

27
Characteristics of Living Things
  • Kingdom- organisms are placed into kingdoms based
    on their ability to make food and the number of
    cells in their body.

28
Characteristics of Living Things
  1. Phylum (phyla is plural)- In the Plant Kingdom,
    phyla are sometimes called divisions. In the
    Animal Kingdom, there are 35 different phyla.

29
Characteristics of Living Things
  1. Class, Order, Family-these levels become even
    more specific. Each level has fewer organisms
    that have more in common with each other as you
    move down the levels.

30
Characteristics of Living Things
  1. Genus- contains closely related organisms. The
    genus is the first word in an organisms
    scientific name

31
Characteristics of Living Things
  • Species- consists of all the organisms of the
    same type which are able to breed and produce
    young of the same kind. The species is the second
    word in an organisms scientific name.

32
Hybrid Species
  • Only animals from the same species can produce
    offspring that are fertile.
  • Liger

33
Hybrid Species
  • Only animals from the same species can produce
    offspring that are fertile.
  • Leopon

34
Hybrid Species
  • Only animals from the same species can produce
    offspring that are fertile.
  • Pumapar

35
Hybrid Species
  • Only animals from the same species can produce
    offspring that are fertile.
  • Zorse Zonkey

36
Hybrid Species
  • Only animals from the same species can produce
    offspring that are fertile.
  • Wolphins

37
Hybrid Species
  • Only animals from the same species can produce
    offspring that are fertile.

    offspring that are fertile.

Characteristics of Living Things
  1. Most scientists classify organisms into 5
    kingdoms Plants, Animals, Protists, Fungi, and
    Monera.

42
5 Kingdoms
  • 14. Kingdoms
  • 1) Plants (Plantae)- the plant kingdom is made
    up of plants. Plants are autotrophs, they make
    their own food. Plants are made up of many cells.
    Plants are divided into 2 groups vascular and
    nonvascular.

43
5 Kingdoms
  • 15. Kingdoms
  • 2) Animals (Animalia)- the animal kingdom is
    made up of animals. Animals are heterotrophs-
    they must obtain food by eating it. Animals are
    made of many cells. The 35 phyla are divided into
    two groups vertebrates and invertebrates.

44
5 Kingdoms
  • 15. Kingdoms
  • 3) Fungi- the fungi kingdom is made up of molds,
    yeasts, and mushrooms. Fungi are heterotrophs
    because they must absorb their food. Yeasts are
    one celled, while molds and yeasts are made of
    many cells.

45
5 Kingdoms
  • 15. Kingdoms
  • 4)Protists (Protista)- the protists are made up
    of organisms that cannot easily fit into the
    plant, animal, or fungi kingdoms. They are one
    celled organisms with a nucleus or simple
    multi-celled organisms.

46
5 Kingdoms
  • 15. Kingdoms
  • 5)Monera- the Monera kingdom is made up of
    bacteria. Their cells do not contain a nucleus.
    Some bacteria are autotrophs, some are
    heterotrophs.

47
New 6 Kingdoms
Bacteria- organisms with no nucleus
Archaea- single cell organisms with no nucleus
that live in extreme conditions
