1. Classification Biologists have estimated that there are many trillions of organisms on our planet. We need to classify or sort them into groups to help us study them.

2. Classification
Biologists work with a system of five kingdoms. The key differences between kingdoms relate to whether the organisms are unicellular or multicellular, how the organisms obtains their food (nutrition), and whether they are mobile or not (movement).

3. 5 Kingdoms
Organisms are put into one of the kingdoms because of difference in movement, nutrition and cell structure.

4. 5 KINGDOMS

5. KINGDOM MONERA Bacteria
Unicellular organisms with a cell structure
different to all other living organisms.
Do not have a nucleus.
Extracellular digestion
Decomposers
Use flagella for movement

6. KINGDOM PROTISTA (Usually) Single celled organisms but their
cells are more like plant and animal cells
because they have a nucleus.
Everything that doesn’t fit easily into the
other four groups ends up here!
Examples: euglena, paramecium, amoeba
Some carry out photosynthesis.

7. KINGDOM FUNGI Fungi are a huge group that can be as
little as a single celled yeast.
Yeast are used to brew beer, make wine
and rise bread.
Some fungi are huge (eg. Mushroom).
Fungi reproduce using spores and they have a nucleus.
Extracellular digestion
Decomposers

8. KINGDOM PLANT Multicellular with nucleus.
Immobile but parts move towards water
(roots) or sunlight(shoot).
Producers as they make their own food.

9. KINGDOM ANIMAL Multicellular with nucleus. Moving bodies and parts
Internal digestion of food
Consumers (=cannot make their own food)

10. Compare and contrast: Plant and Animal Kingdom
Similarity
Differences
Both multicellular
Both cells have
nucleus
Both their body parts move
Plant cells have
chloroplast
Animals can’t make
their own food but plants can.
Animals can move
freely but plants can’t

11. Compare and contrast: Plant and Fungi Kingdoms
Similarity
Differences
Both multicelullar
Both immobile
Fungi reproduces with
spores but plant
reproduces with seeds.
Plants can make their
own food but fungi
cannot.
Fungi digests food by
extracellular digestion.

12. classification levels
Related species are put into a genus. Similar genera are put into a family. Similar families are put into an order. Similar orders are put into a class. Similar classes are put into a phylum, and finally related phyla go into a kingdom.

13. Kingdom

14. Binomial System An organism’s classification
should include a clear description, an accurate diagram, and
its unique name (denoted by the
genus and species).
