Unit 1: ANIMAL PLANETS, Vertebrates and invertebrates animals.

1. ANIMAL
PLANET

2. VITAL FUNCTIONS
• There are vital functions that chracterise all living
things.
• NUTRITION
• INTERACTION
• REPRODUCTION

3. NUTRITION
• Some living things (like human and animals) get their
food by eating other living things.
• They can be clasifiied into three groups:
• HERBIVORES: They only eat plants. ZEBRAS.
• CARNIVORES: they eat other animals. LEOPARDS
• OMNIVORES: they eat other animals and plants.
MONKEYS.
• However, plants are able to make their own food.

4. INTERACTION
• We receive information from the world through our
senses. Then, we make decisions.
• For example, when we are cold, we put on a
jumper.
• Acting and reacting to the wrold around us is
known as INTERACTION.

5. REPRODUCTION
• Lions can give birth to lion cubs, and plants can use
their seeds to make new plants.
• There are different types of reproduction:
• OVIPAROUS – Ducks are born from eggs.
• VIVIPAROUS- Urchins give birth to their young.
• SEEDS- Beans are born from seeds.

6. VERTEBRATES

7. VERTEBRATES
• All vertebrates have an internal skeleton that is
made up of many bones.
• Some vertebrates are viviparous. (dogs and human
veings)
• Other vertebrates are oviparous (frogs, eagles and
lizards)

8. BODY PARTS OF
VERTEBRATES
• Commonly the bodies of vertebates can be split
into:
• HEAD
• BODY
• LIMBS

9. INVERTEBRATES

10. Some animals don’t have
skeletons. They are
INVERTEBRATES.

11. INVERTEBRATES
• All invertebrates have one thing in common: they
are OVIPAROUS
• They aren´t VIVIPAROUS

12. Invertebrates
don’t have a backbone.

13. ARTHROPODS
• Arthropods is the biggest and most important
group of invertebrates.
• All arthropods have an external skeleton that
protects their body.
• They also have many legs.
This group can be divided into three subgroups:
-insects (six legs)
-arachnids (eight legs)
-crustaceans (ten legs)

14. INSECTS
• It is the largest group of arthropods.
• Their body is divided into three parts: HEAD, THORAX
AND ABDOMEN.
• They have two antennae and may have wings.

15. Insects are invertebrates.
bee ladybird
cockroach fly mosquito

16. ARACHNIDS
• Their body is divided into two parts: Cephalothrax
and abdomen.
• Arachnids don´t have antennae or wings.

17. CRUSTACEANS
• Their body is divided into two parts:
• Cephalothorax and abdomen
• They have two antennae but don´t have wings.

18. SPONGES
• Sponges live at the bottom of the sea.
• They are fixed to the ground so they cannot move
around.
• Their body is full of holes known as pores.
• Food and water enter their body through these
pores

19. JELLYFISH
• Jellyfish can be very dangerous animals.
• They have poisonous tentacles that they use to hunt
other animals.

20. ECHINODERMS
• Starfish and sea urchins are echinoderms.
• They have many small feet that they use to move
along the bottom of the ocean.
• SEA URCHIN STAR FISH

21. WORMS
• Worms have a long soft segmented body that is
made up of rings.
• Some worms live in the ground, while other live in
water.

22. MOLLUSCS
• All moluscs have soft muscular bodies that they use
to move around the ground or through the water.
• There are three types of mulluscs that have shells:
• Molluscs with two shells. MUSSEL
• Molluscs with one shell. SNAIL
• Molluscs with an internal shell. SQUID

23. REVIEW
• All living things have three vital functions in order to
grow and live. These are: nutrition, interaction and
reproduction.

24. REVIEW
• Animals eat food to get energy. Carnivores only eat
meat and hervivores only eat plants. Omnivores eat
both meat and plants

25. REVIEW
• Some animals give birth to their young and others
lay eggs.

26. REVIEW
• Animals with bones are called vertebrates and
animals without bones are called invertebrates.
Some animals have an external skeleton known as
a shell.

27. REVIEW
• The biggest groups of invertebrates are arthropods..
They can be classified into three groups: arachnids,
crustaceans, and insects. Each of these groups has
a different number of legs.

28. REVIEW
• There are other groups of invertebrates that live in
water. They are jellyfish, molluscs, sponges,
echinoderms and worms.

29. TRUE OR FALSE?
• Spiders are arthropods because they have an external
skeleton and many legs. TRUE

and an internal skeleton. TRUE
• All invertebrates are oviparous. TRUE
• Arthropods have an external skeleton and many legs.
TRUE
