- 1Mould cell wall compositionChitin
Glucans (mannans, galactosans, cellulose,)
Glycoprotein
Amorphous glucans - 2Yeast cell wall compositionNO chitin
Mannans - 3Fungi cell membraneSimilar to humans
BUT instead of cholesterol it has ERGOSTEROL - 4Yeast general featuresCircular, oval, cylindrical
3-30 um
unicellular
Reproduction:
Sexual and asexual - 5Name an example of a yeastSaccharomyces cerevisae
- 6Moulds basic featuresThreadlike+branched filaments
Filament = HYPHAE
Mass of filaments = mycellium
Contains large amount of nucleates - 7What is a mould with cross walls calledSeptate ( sound similar to separation)
- 8What is a mould with no cross walls calledCoenocytic
- 9Mushrooms general featuresGrows in favourable conditions (moisture + heat) in autumn
Cap
Gills
Stalk
Volva
Mycelium - 10Life cycle of a mushroomSpores
Spore germination
Mycelium
Mushroom primordia
Mature mushroom - 11Asexual reproduction main pointsOffspring identical to the parent
*spores
*germination
*mycelium - 12Asexual reproduction in YEAST1) Fission - a yeast cell splits down a middle to give two new cells
- Schizosaccharomyces pombe
2) Budding - a cell buds of from another
-Candida albicans
=growth is VERY quick
= evolve quickly
=resistant to medication - 13Asexual reproduction mouldsExospores (condiospores) gerimnate
Mycellial differentiation
1) Vegetative mass (bottom + absorbs nutrients)
2) Aerial form (rise up+ produce sexual spores)
-sporulation occurs
-spore germinates
-sporangia - 14—
