2.1 Welcome to the group

• Organising things is called: Classification
• Taxonomic group/taxon: the groups scientist have made to organise living things
• the binomial system: the system in which each organism is named after ist genus, the first part of its name and is species, the second part. 
• kingdom: the largest taxon, at the upper level
• species: the smallest taxon, at the botom level

the four kindoms

the four kindoms

Cats (Felidae)

Predators (Carnivora

native animals of the Netherlands

www.natuurmonumenten.nl

Common plants, birds and insects of the Netherlands

on page 182-184.

Exotics: species that have been brought to an area on purpose or by accident, but manage to survive in that area. 

Tijgermug     tiger musquito.  

Stegomya albopicta

Native to the south east of Asia. Is has spread to many countries through the transport of goods. The larva hides in the bamboo. 

It is able to spread viruses who are tropical diseases.

what is a native animal in the Netherlands?

1. rabbit
2. beaver
3. red crayfish
4. great tit

The red crayfish is an 

invasive exotic.

The red crayfish is native to 

the United States.

Since his introduction is had out-competed the native European crayfish

In what way did the red greyfish out-competed the European crayfish? (answer in the next slide)

Why did the red crayfish out-competed the European grayfish

1. by a fungus what causes a deadly plaque
2. it can survive in a wider range of habitats
3. it can survive better in dry periode.
4. it can migrate from one pond to another

Amoebae proteus

pseudopodia, which means 'false foot"

engulfing food

unicellular

Mosses & liverworts

simple leaves

no proper sterns

spores inside capsules

Ferns

• leaves
• true roots
• strong sterns
• vascular system
• spores inside patches, called 

    sporangia

Gymnosperms ( non-flowering)

conifers: Seeds naked and develop in cones. 

male: pollen: seeds

They have needle shape leaves to minimise water loss

Angiosperms (flowering plants)

Unit 2 Classification

Monday 15 november

• Discuss 2.6 Identifying species
• Identify a leaf from a tree and a soil animal
• Check the exercises from 2.6
• Start with the animal passport

Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification.

A branching key.

This key contains descriptions

that branch out into even more descriptions, ending in the names of the organisms or items. 

Identify organisms in class

• choose an mini animal and a leaf
• make a  biological drawing 
• use the branching key to identify the leaf and animal
• Look on internet for the english and binomial name
• Put the english and binomial name on the drawing. 

Check and correct your work

• Check and correct the exercises 2.1- 2.4 - 2.5 and 2.6
• Answer the questions on page 51 in your text book.
• Have your completed all the summary's? 

Tomorrow we will start with the Animal passport!

The test of Chapter 2 is next monday!
