Grade 9 ScienceKingdoms of Life

Classification of Living Things

Living things can be sorted into

these 5 kingdoms…but it’s not the only

way!

Kingdom Moneran (Bacteria)

Kingdom Protista

Kingdom Fungi

Kingdom Plantae

Kingdom Animalia

Kingdom Moneran - Bacteria microscopic, single-celled

organisms do not have a nucleus but do have

a ring of DNA (prokaryotic) do have a cell wall Some can photosynthesize

(autotrophic) Most are heterotrophic

Bacteria Some bacteria are useful – Lactobacillus

bulgaricus used to make yogurt Some bacteria are pathogens and cause

disease, like Pneumococcus that causes pneumonia

Kingdom Protista single-celled organisms with a nucleus

(eukaryotic) All live in water Includes a huge variety of organisms

from giant kelp to amoeba All have the same cell structure Some can photosynthesize, others

can’t

Kingdom Protista Chlorella Plasmodium Kelp Algae

Kingdom Fungi Eukaryotic cells Cannot photosynthesize Heterotrophic Have cell walls Some single celled like yeast Most multicellular (molds,

mushrooms)

Kingdom Fungi

Kingdom Plantae Multicellular – made up of lots of

cells Make their own food by

photosynthesis (autotrophic) Have cell walls Lots of examples: flowering

plants / non-flowering plants

Kingdom Plantae Mosses Ferns Flowering plants Non-flowering

plants

Kingdom Animalia Multicellular – made up of may

specialised cells heterotrophic Can be further classified into

vertebrates and non-vertebrates then into classes such as amphibians, reptiles, birds, mammals, insects

Animals you may not have seen…

Aye-aye lemur Star-nosed mole Blob fish Alligator snapping

turtle 3-toed Sloth Preying mantis Nudibranch Some type of

jellyfish!

Limitations Much more

DNA evidence now

Three Domain System is more recent

Another way of organizing…

Lichens•formed by a fungus and cyanobacteria living symbiotically

* first to enter an uninhabited area, slowly break down rock-*they are indicator species: they are very sensitive to environmental change, don't tolerate chemical pollution, eg. sulphur dioxide

Don’t fit into ANY Kingdom!

What about Viruses? Are they living or not?? No one can decide!!
