2. Look at these ecosystems.
Which living things are plants?
Which living things are vertebrate animals?
Which living things are invertebrate animals?

3. The animal, plant and fungi kingdoms
trees
Bushes
grasses
Can plants move around? Can they make their own food?
 MOVE AROUND  MAKE THEIR FOOD
vertebrates
invertebrates

yeast
Tree living fungus

4. Cells All living things are made up of cells.
The smallest are so small you can only see them with a microscope.
Different cells have different functions.
Most living things are made up of many types of different cells but some, like bacteria, have just one cell.

5. What do invertebrate animals have instead of a backbone?
Animal Kingdom: invertebrates
What do invertebrate animals have instead of a backbone?
Molluscs   
Jellyfish

7. Animal kingdom: vertebrates
How do animals breathe?
Mammals
Birds
Fish
Reptiles
Amphibians

8. Both with LUNGS and GILLS
Animal kingdom: vertebrates
How do animals breathe?
With LUNGS
With GILLS
Mammals
Birds
Fish
Both with LUNGS and GILLS
Reptiles
Amphibians
Animals take oxygen from the air with LUNGS and from the water with GILLS.

9. Animal kingdom: vertebrates
How do animals reproduce?
Mammals are viviparous.
The others are oviparous.
Some animals are born directly from their mother: VIVIPAROUS.
Some others lay eggs: OVIPAROUS.

10. Animal kingdom: vertebrates
What do animals eat?
Some animals are carnivores, some are herbivores and others are omnivores.

11. Plant kingdom How do plants reproduce?
Some plants have sexual reproduction: pollen goes from the stamen to the pistil of the same plant or a different one.
Some plants have asexual reproduction: there are no flowers or fertilisation.

12. Both sexual and asexual
Plant Kingdom
How do plants reproduce?
Some plants have sexual reproduction: pollen goes from the stamen to the pistil of the same plant or a different one.
Insect pollination
Wind pollination
Self-pollination
Some plants have asexual reproduction: there are no flowers or fertilisation.
Runners
Tubers
Both sexual and asexual

13. Plant Kingdom Why is photosynthesis imortant? OXYGEN = LIFE
PLANTS = OXYGEN
PLANTS = LIFE!
Every animal needs oxygen to live.
Plants produce oxygen and consume carbon dioxide.

14. Plants and animals living together
animals from the same species  POPULATION
different populations in one place  COMMUNITY
the place they live  HABITAT
habitat + community = ECOSYSTEM

15. How can you look after living things?
We shouldn’t climb trees, pick up flowers, remove animals from their habitats, make fires in the forest or touch wild animals.
We should feed birds in the winter.
