Classification= ordening

Remember: Classifying organisms

Characteristics that are used to classify:
- Cell nuclei
- Cell walls
- Chloroplasts

Cell characteristics

Which kingdom hasn't got a nucleus

1. Bacteria
2. Fungi
3. Plants
4. Animals

Which kingdom has got chloroplasts

1. Plant
2. Fungi
3. Bacteria
4. Animal

Which kingdom does not contain a cell wall?

1. Bacteria
2. Plant
3. Animal
4. Fungi

 The animal kingdom

Two features play key role:
- Symmetry
- Skeleton

7 phyla (they all have their own features) of the animal kingdom:
Sponges, Cnidarians(kwallen), worms, mollucs(mossel, slak), arthropods (spinnen, vliegen), echinoderms(zeester), Vertebates (gewervelden). Video is mainly about the last one.

We can classify animals into phyla based on:

1. Number of legs
2. Body shape
3. Symmetry
4. Type of skin

3. No skeleton

What type of symmetry does a snail (slak) have?

1. Bilaterally symmetrical
2. Radially symmetrical
3. Asymmetrical

What type of symmetry does a sand lizard (zandhagedis) have?

1. Bilaterally symmetrical

Bs 8 The arthropod (geleedpotigen) phylum

Classification of arthropods

- Insects (insecten)
- Crustaceans (kreeftachtigen)
- Arachnids (spinachtigen)
- Myriapods (duizendpotigen)

Arthropods

• jointed legs
• bodies divided in segments
• have exoskeleton
• many legs

Dutch: ' geleedpotigen'

The vertebrate(gewervelden) phylum

Features: Endoskeleton(backbone,vertebrae)
This phylum is subdivided into classes:
- Fishes
- Amphibians
- Reptiles
-Birds
-Mammals

Vertebrates

Five classes can be distinguished using the following features:

-Skin
- Body temperature
- Respiratory organs
- Method of reproduction

- Environment
