1. Variety of Life

2. Is It Alive? How do you know if something if alive or not?
There are seven life processes (MRS GREN):
Movement
Respiration
Sensitivity
Growth
Reproduction
Excretion
Nutrition

3. MRS GREN
Movement- we need to move around to get food, plants can move their leaves towards sunlight
Respiration- both plants and animals take in Oxygen from the air to release energy
Sensitivity- we are all sensitive to the cold, acidity etc.

4. MRS GREN Growth- We all grow up (and out!)
Reproduction- All living things make more of themselves
Excretion- Getting rid of waste e.g. we breathe out Carbon Dioxide
Nutrition- Eating (plants take in nutrients from the ground)

5. Organisms Organism means living thing There are two big groups: Plants
Animals
There are also bacteria and viruses that make us sick

6. Classification
Carl Linnaeus, a Swedish scientist came up with the classification system
Organisms are placed in groups if they are similar to each other

7. Animals Animals can be divided into: vertebrates (have a backbone)
invertebrates (no backbone)
Which group do we belong to?
Vertebrates
Which group do worms belong to?
Invertebrates

8. Vertebrates There are five groups (BFARM): Birds Fish Amphibians
Reptiles
Mammals

10. Weird Mammals
Dolphins- they have lungs
A Bottlenose Dolphin

11. Weird Mammals
Whales- have lungs
Killer Whales

12. Weird Mammals
The Blue Whale- the largest animal

13. Weird Mammals
Bats- they are related to rodents

14. Reptiles
The Tortoise live on land

15. Reptiles
Turtles live in water
The Green Sea Turtle

16. Birds
Emperor Penguins are one of the few organisms to live in Antarctica

17. Amphibians
The Fire salamander can re-grow legs that have been cut off

18. Amphibians
The poison dart frog is lethal to humans

19. Fish
Sharks are fish, they have gills
The Great White Shark

20. Annelids These are Earthworms and leeches They are invertebrates
They have rounded bodies
Their body is segmented

21. Arthropods
This big group (phylum) of ancient invertebrates include smaller groups (classes) of insects, spiders, millipedes and crabs
They have a hard body
It is divided into segments
They have jointed legs

22. Arachnids
They have 8 legs
Two body parts and no wings

23. Insects They have 6 legs and two pairs of wings
They have 3 body parts:
Thorax
Head
The Damselfly
Abdomen

24. Insects (Stag Beetle)
Head
Thorax
Abdomen

25. Molluscs These are slugs, snails, squid and the octupus
They have soft bodies with a head and a muscular foot

26. Plants These are divided into:
Flowering plants (conifers and seed producing flowers)
Non-flowering plants (Algae, ferns and mosses)

27. Non-Flowering Plants
Algal bloom on a river

28. Flowering Plants
This Passion Flower makes seeds

29. Keys This is a question key
It can be used to separate organisms according to their characteristics
Can you name the invertebrate A, B, C and D
A= Ant
B= Mite
C= Spider
D= Mayfly
