3.4 Worms

Slide 8 - Slide

Monday 29th of november
  • Check if all the Animal passports are uploaded in teams
  • Check the exercises 1-4 on page 51 - 52
  • Read and make a summary of 3.4 togheter
  • Make the exercises 3.4 
  • Discuss the questions of the test

Slide 9 - Slide

3.4 Worms page 63-64

  • Open your book on page 63.
  • Open your notebook at summary 3.4
  • Read when its your turn

Slide 10 - Slide

Body plan
  • long thin bodies
  • bilateral symmetric
  • no skeleton
  • mouth and anus
  • many shapes & sizes 
  • Three types:
  1. segmented worms
  2. roundworms
  3. flatworms 

Slide 11 - Slide

Segmented worms
  • Also called ringworms 
  • The rings are the segments
  • eats soil, the soil moves trough the digestive tract (het spijsverteringskanaal)
  • food: little pieces of plants and animal matter ( dierlijk materiaal)
  • excretes what is left over

Slide 12 - Slide

Roundworms
  • they lack segments 
  • bodies look like threads
  • live in soil
  • some are parasites, living inside animal and plant.
  • roundworm infections: eggs live in soil and contaminated faeces. the eggs can get into the body through the mouth. In the intestines your worms wil hatch (uitkomen) from them. 
  • parasites causes disease, but do not kill the organisms they feed on.

Slide 13 - Slide

Slide 14 - Slide

Flatworms
  • Long flat bodies
  • simplest bodyplan of all worms
  • some have no muscles 
  • live in water, absorb food through their skin
  • some are parasites, live inside animals and cause problems in their host.

3.8 Vertebrates (gewervelden)
What do vertebrates have in common?

  • the backbone consists of vertebrae (wervels)
  • They have muscles and a endoskelet
  • There a five classes: - Fish, amphibians, reptiles, birds, mammals

Fish
  • aquatic; they live in water
  • lay eggs, fertilised externally, soft outer covering 
  • some are livebearers (levendbarend)
  • fish are coldblooded; same temperature environment
  • bodies covered with scales (schubben)
  • bodies are streamlined
  • fins for balance and controle movement
  • breathe by gills

Slide 30 - Slide

How do gills work?
  • bony fish have gill cover
  • cartilaginous fish have gill slits ( shark and stingray (rog))
  • gills are made up by gill arches an filaments
  • The filaments make a larger surface to take oxygen out. 
  • also gills: mayfly nymph, sea slug

Slide 31 - Slide

Slide 32 - Slide

Amphibians
  • Include Toads, frogs and salamanders.
  • Live in moist environments
  • skin moist and wet, no scales
  • survive in water and land

  • many have lungs too
  • lay eggs in water, eggs have a soft slimy scale
  • larva of a frog is tadpole; who have gills and live in water. 
  • newt lives most of the time in the water, salamander on land
