Review Start b9: Vertebrates

Goals: 

-I can distinguish the 5 classes of vertebrates by using 4 characteristics. 

-I can explain the benefit (voordeel) of 2 transitions in evolution of vertebrates. 

Vertebrates have 4 classes.

1. True
2. False

Amphibians have:

1. Scales + eggs with leathery shell.
2. Mucous+ eggs with leathery shell.
3. Scales + eggs without shell.
4. Mucous+ eggs without shell.

Reptiles are able to lay their eggs safely on land, because

Which class do turtles belong to?

-Have scales(schubben) covered in mucous(slijm). 

-Use gills(kieuwen) to breathe.

B9: vertebrates

Amphibians:

-Live in water and land.

-Have skin covered in mucous. 

-Use gills and skin to breathe when young. Lungs and skin when mature(volwassen).

-Are cold-blooded.

B9: vertebrates

Reptiles:

-Live (mostly) on land.

-Have dry scales as skin.

-Lay eggs with a leathery shell.

B9: vertebrates

Birds:

-Live (mostly) on land and sky.

-Have feathers(veren). 

-Use lungs with air-sacs to breathe.

-Are warm-blooded.

-Lay eggs with a chalky(kalkachtig) shell.

B9: vertebrates

Mammals:

-Feed young with milk.

How do you recognise vertebrates?

1. They have 4 legs.
2. They have scaley skin.
3. They have a backbone.
4. They live on land.

How are mammals different from other vertebrates?

1. No mucous on their skin.
2. They feed their young with milk.
3. They are warm-blooded.
4. They use lungs to breathe.

Name two features only a reptile has.
