1. Living Things

2. What Makes something alive??
Which of the following are alive?
Fish
Bacteria
Tree
Insect
Rock
Baby
Frog
Water
Mushrooms

3. What do all the Things you have identified as living have in common?
Movement
Respiration
Sensitivity
Feeding
Excretion
Reproduction
Growth
Remember MRS FERG

4. Movement Movement means the ability of an organism to change position
Some organisms can move the entire body
Some organisms can move part of the body
eg plants
Some organisms can move both their entire body, and each section of the body eg insects, amphibians, reptiles, mammals
Most organisms move towards things they need and away from things that harm them

5. cell glucose oxygen Respiration carbon dioxide water energy
Respiration means
releasing energy from food
Glucose in the food is broken down inside cells, and energy is released
Most organisms use oxygen for this process
cell
glucose
oxygen
energy
water
carbon dioxide

6. Sensitivity
Sensitivity means the ability of an organism to gather information and respond to it
Some of the things that cause living organisms to respond are light, sound, touch, chemicals, gravity…eg:
Roots grow downwards in response to gravity, shoots grow towards light
Both plants and animals use their sense of touch when climbing
Predators use sound and smell to hunt for prey

7. Feeding Feeding means getting Food
All living organisms need food for energy
Plants can make their own food using energy from the sun (photosynthesis)
Animals need to find an outside source of food

8. Excretion Excretion means the removal of toxic chemical substances
toxic substances are poisonous and
may harm cells if not removed
examples of toxic substances are
carbon dioxide and urea

9. Reproduction Reproduction means
producing more organisms of the species
Some organisms reproduce from one parent only – this is called ASEXUAL reproduction
Other organisms reproduce by combining one cell from a male with one cell from a female – this is called SEXUAL reproduction

10. Growth Growth means the organism develops into an adult
For micro-organisms, this means their cell grows to full size before reproducing
For multi-celled organisms, this means that cells divide, organs grow in size, and systems develop maturity

11. 2 main groups of living things
Plants
Animals

12. There is a huge variety of Animals
This means that we need to divide the animal kingdom into 2 groups
Vertebrates – Have a backbone
Invertebrates – Have no back bone

13. Can you guess the Vertebrates + Invertebrates?
Bone Blaster game
Snail
Ant
Dolphin
Hedgehog
Crab
Fish
Starfish
Bee
Snake
Lobster
Platypus
Spider
Worm
Fox
Frog
Dragonfly
Blackbird

14. Vertebrates are divided into 5 groups

15. Plants
Plants are living organisms fixed in one position and cannot move around they can only moves parts
Plants contain a green chemical called chlorophyll and can make their own food by photosynthesis

16. How do you Identify Plants + Animals you don’t know?
A key is a system that gives you a few simple questions at a time and you work through the key by answering questions and eventually identifying organisms
Lets try a few online!
And another!
Now see if you can use the key on page 3 of your book
