Chapter 6Multi-cellular OrganismsLesson 1

• How are living things grouped?

2
Vocabulary Preview

• Classification process of grouping similar
  things together
• Kingdom a major, large group of similar
  organisms
• Species a single kind of organism that can
  reproduce among its own kind

3
Classification

• When you walk into your kitchen at home, you
  probably know where to find most things.
• The forks are in a certain drawer with spoons and
  knives.
• Soups, vegetables, macaroni are all in a pantry
• Can you think of other items in your kitchen that
  have a certain place?
• Putting similar items together in a kitchen makes
  cooking and cleaning up easier.

4
Classification

• The process of classification, or grouping
  similar things together, makes sense in a
  kitchen.
• It also helps scientists who study living things.
  
• No one can know everything about the 10 MILLION
  different kinds of organisms that live on Earth.
• By identifying characteristics that living things
  share, scientists can group similar organisms
  together.
• Scientists look for similarities in the way
  organisms look, live, eat, move, grow, change and
  reproduce

5
CLASSIFICATION

• What characteristics do these two animals share?

6
Grouping Living Things

• Scientists classify for many reasons.
• How can classifying make things easier?
• It makes finding/sharing information easier
• When they discover a new organism they can look
  at other organisms they have already studied

Kingdoms.ppt
One classification system divides all organisms
into five kingdoms Animals, Plants, Fungi,
Protists, and Bacteria. What characteristics does
each kingdom have?
8
Grouping Living Things.

• Scientists classify living organisms into major,
  large groups called kingdoms.
• All members of each kingdom have certain
  characteristics
• Different methods of classification have
  different members of kingdoms-either five or six

9
Grouping Living Things..

• Scientists need to classify animals together
  because animals are made of many cells and they
  feed on other living or once living things.
• Plants have many cells also, but they make their
  own food.
• Fungi are many-celled organisms, but they dont
  make their own food. They absorb it from the
  remains of other organisms.
• Protists are one celled organisms
• Bacteria are all one celled organisms
• Their cells have no nucleus
• Most feed the way fungi do, but some make their
  own food.

10
Smaller Groups

• Kingdoms include many different organisms.
• The members of each group share more and more
  characteristics.
• The smallest group contains only one kind of
  organism.

Smaller Groups

• First Step divide each kingdom into smaller
  groups.
• A Phylum-is a major group within a kingdom
• Organisms in a phylum have more characteristics
  in common than do organisms in different phyla.
• Phylas are divided into classes, classes are
  divided into orders, and orders are divided into
  families.
• Just as in your family, members of the same
  family share many characteristics
• Like human families, they have individual
  differences.
• A genus can contain one or more specied.
• A Species is a unique kind of organism

13
Smaller Groups..

• Every different kind of living thing has its own
  specific name.
• This name includes the names of the smallest two
  groups-genus and species
• Example The scientific name for a house cat is
  Felis domesticus. Felis is the names of its
  genus.
• The names of its species is domesticus.
• House cats and only house cats have this name
• When scientists use this name they know they are
  only talking about house cats.

14
Smaller Groups.

• To divide larger groups into smaller groups,
  scientists look for characterisitics that some
  members of one group have but others dont.
• Example Butterfly is the only animal in the top
  group that doesnt have a backbone.
• Soooo the butterfly doesnt belong to the same
  phylum as the other animals.
• At the next level, all the animals except the
  fish are mammals, so the fish doesnt belong
• As the group gets smaller, each group includes
  organisms that are more alike
