  2. YEASTS • Unicellular organisms • They live everywhere around us • Useful • An eukaryotic cell • Reproduction by budding • Heterotrophic • A thick cell coat

  3. YEASTS – A CELL

  4. YEASTS - BUDDING • A bud – a new growing cell • A cell wall • A membrane • Cytoplasm • A mother cell

  5. YEASTS - IMPORTANCE • Brewer´s yeast – beer and wine production, bread baking and yeast bakery products baking • Yeasts include B vitamin and other important substances • A yeast of genus Candida – a skin disease

  6. FUNGI • Organisms differ from plants and animals • Decomposers They differ from animals They differ from plants • They do not absorb organic substances (they absorb them in solutions) • A different cell structure • They have a cell coat • They do not have chloroplasts • They are not able of photosynthesis • They are heterotrophic

  7. FUNGI– WAYS OF GETTING OF NUTRIENTS

  8. FUNGI- IMPORTANCE • Stimulating food • Cheese production (mould shaping fungi) • Pharmaceutical industry (antibiotic production) • Dangerous of poisoning • Mycorrhiza = symbiosis of a fungus + a plant

  10. FUNGI WITHOUT SPOROCARPS • CLAVICEPS PURPUREA

  13. FUNGI WITH SPOROCARPS - tubes - sporangium (spore case) - spores

  14. FUNGI WITH SPOROCARPS Fungi with an ascus on the gills - gills - an ascus

  15. FUNGI WITH SPOROCARPS • PARASOL MUSHROOM

  16. FUNGI WITH SPOROCARPS • FLY AGARIC

  17. HOUBY S PLODNICEMI • SUMMER CEP (PENNY BUN)

  18. HOUBY S PLODNICEMI • BOLETUS REDICULATUS
