1. Classifying Living Things

2. Kingdom
• Living things are
divided into 5 large
groups called
kingdoms
• kingdoms share
similar characteristics
• bacteria(monerans),
protists, fungi, plants,
animals

3. Classification
• Classification helps
scientist compare
different animals
• What do these animals
have in common?
• Would they be put in
the same group?

4. Groups
• The most general
group is the kingdom
• each step eliminates
organisms until there
is only one
• The species is the
smallest most exact
group

5. Characteristics
• To divide
groups to make
them smaller
scientist view
characteristics
• How would we
classify the
groups at left?

6. Plant groups
• Plants are classified
just like animals
• Two large groups are
vascular - have
transport tubes(trees)
• non- vascular = absorb
nutrient into
cells(mosses)

7. • What does this circle
graph tell you about
where most species of
animals live?

8. Animal groups
• Vertebrates =
backbones
• Invertebrates = no
backbone
• What would this
octopus be?
• What are some
examples of each?

9. Vertebrates
• Broken into five
groups
• fish, amphibians,
reptiles, birds, and
mammals
• What are some
differences between
these groups?

10. Fish
• Have gills that absorb
oxygen dissolved in
water
• live entire life in water
• have scales
• cold blooded
• most lay eggs
• More than 19,000
species

11. Amphibians
• Begin life in water
• live on land as adults
• must return to water to
lay eggs
• Moist smooth skin
• cold blooded
• frogs, toads, newts,
salamanders
• More than 4,000 species

12. Reptiles
• Cold blooded
• dry scaly skin
• most lay leathery eggs
on land
• More than 6,000
species

13. Birds
• Lay hard shell eggs
• warm blooded
• have feathers, beaks,
and scaly legs
• Have light bones
• More than 9,000
species

14. Mammals
•
•
•
•
Warm blooded
have hair
live birth
produce milk for
young
• More than 4,000
species

15. Invertebrates
• All lack a backbone
• have different body
forms and live in
different areas
• many divisions
• sponges, worms,
mollusk, echinoderms,
arthropods

16. • Largest group of
invertebrates
• have exoskeletons
• crustaceans (crabs,
lobsters, shrimp)
• insects (beetles,
butterflies, ants,
roaches, bees)
• arachnids (scorpions,
ticks, mites, spiders)
Arthropods
