Welcome everyone 

 Think about...

• Take off your coat, hat/cap off.
• Mobile in the phone bag (on silent).
• Book/laptop + notebook, pen on the table. Bag on the floor.
• Sit in your own place.

• 5 minutes.

What is the principle difference between eukaryotes and prokaryotes?

1. their size
2. their activity
3. their nuclei
4. their cell wall

Write the sentence you use to remember all the classification group names.

A species is more specific than a genera.

1. true
2. false

A phylum is more specific than a class

1. True
2. False

There are 2 kingdoms in the domain prokaryotes.

1. True
2. False

How many kingdoms make up the domain eukayotes?

1. 3
2. 4
3. 5
4. 6

Learning objective 3.2

• You can distinguish between species and breeds.
• You can explain how the classification of organisms depends on similarity and kinship.

Basics 2 - Similarity and kinship

• kinship = verwantschap 
• Organisms from the same kingdom have fewer similarities
  
• example: Fish and a zebra
• Organisms from the same genus                                                     have a lot of similarities
• example: Lion and a tiger

Species?

• What is a species?
• Organisms that reproduce together and make fertile offspring.                                                                                                    (They make babies that can                                                                have babies).

Breed?

Evolution

• Organisms that belong to the same species                            have a lot of similarities -->Variation
• Selection - a bird can not see the dark snails so eats the light ones first. The dark shells survive and make babies. Become more common.
• Evolution: the development of life on Earth in which species arise, change and/or disappear

Kinship

Animals with a close common ancestor 

are closely related 

• More closely related means 

       more similarities in DNA                                             overeenkomst in DNA

common ancestor of Tuna, salmander, turtles and leopards

Common ancestor of all these groups

Common ancestor of turtles and leopard

Make assignments of 3.2

Read page 176 until 178 in ZS

make assignment 1 until 8

Learning objective 3.2

• You can distinguish between species and breeds.

Species: organism can have fertile ofsprings

breed: variation of a species 

• You can explain how the classification of organisms depends on similarity and kinship.

species with a common ancestor are related. the more similarites the more they will be in the same group.
