Recap questions

When do two organisms belong to the same species?

Which of the following is correctly listed in the hierarchical classification system used in taxonomy?

1. Kingdom, Class, Order, Phylum, Family, Genus, Species
2. Kingdom, Phylum, Class, Order, Family, Genus, Species
3. Kingdom, Phylum, Order, Class, Family, Genus, Species
4. Kingdom, Phylum, Family, Class, Order, Genus, Species

Kindom of bacteria

Are all bacteria dangerous for humans?

1. yes
2. no

Making a PIF

PIF = Personal Idiom file = list of new words

• On your laptop create a new document, call it: 'PIF Biology'
• Make a table like the example
• If you find/read/hear words during the lessons that are unfamiliar/unknown/difficult, add them to your PIF!
• Make sure to save the document well! You will use it throughout the year!

Extend your PIF

1. Read Chapter 3.1
   
2. Write down the bold words and other words you don't know
3. Look up the meaning of the words and write them in your PIF
4. Lookup synonyms of the words
   

Taxonomy

Organising life into different groups

•  Kingdom
•  Phyla
•  Classes

Phylum/Phyla

Mueum/Musea

Classification groups:

today we are going to discuss the phyla of the animal kingdom

According to different characteristics

We classify animals mostly with the help of 2 characteristics: symmetry and skeleton.

symmetry

Skeleton

Phyla of the animal kingdom

Phylum	symmetry	skeleton
sponges	no	internal: fibers
cnidarians	radial	often none
molluscs	bilateral	no or shell
arthropods	bilateral	external: exo skeleton
echinoderms	radial	internal: calcium
vertebrates	bilateral	internal: bones

Which Phylum are we missing?

Phylum	symmetry	skeleton
sponges	no	internal: fibers
cnidarians	radial	often none
molluscs	bilateral	no or shell
arthropods	bilateral	external: exo skeleton
echinoderms	radial	internal: calcium
vertebrates	bilateral	internal: bones

Which Phylum are we missing?

Worms
