  • Cell wall

Slide 10 - Tekstslide

Slide 11 - Video

Unicellular fungi
  • Reproduction by budding
  • cells divide by forming buds
  • Example: yeast

Slide 12 - Tekstslide

Multicellular fungi
  • Reproduction by spores
         - Toadstools
         - at the end of hyphae
  • Examples

Slide 13 - Tekstslide

Useful & harmful
  • Feed on dead bodies of other organisms
  • Make penicillin
  • Biotechnology : bread, beer, cheese, etc.
  • Cause fungal infections
  • Spoil food

Slide 14 - Tekstslide

Bacteria are everywhere

Slide 15 - Tekstslide

Cell characteristics of prokaryotes
All prokaryotes
(bacteria and
archaea)
have:
  • NO nucleus
  • Cell wall
Cell membrane
Cell wall

Slide 16 - Tekstslide

Features of bacteria
  • Always unicellular
  • Very small (too small for most microscopes)
  • Reproduction: Cell division

Slide 17 - Tekstslide

Reproduction
Speed depends on:
  • Temperature
  • Food
  • Species
s
s

Slide 18 - Tekstslide

Useful bacteria
Most bacteria are useful:
  • Help digest food in our intestines
  • Kill harmful bacteria on our skin
  • Feed on dead organisms
  • Can be used in making food: Yoghurt, Sauerkraut

Slide 19 - Tekstslide

Harmful bacteria
  • Cause diseases
  • Spoil food
Antibiotics (like penicillin) kill bacteria
