04 / 04 Thursday
Learning objective:To be able to draw, label and describe the structure of a generalised fungus
Starter1) Define these terms:
- aerobic respiration - anaerobic respiration
2) Give three differences between aerobic and anaerobic respiration
Anaerobic Respiration – without oxygen
Sugar → Lactic acid + H2O + Energy Produces much less energy than aerobic
respiration Lactic acid is used for making sour foods Fermentation is a form of anaerobic
respiration – used for making wines and beers
Fungi Mushrooms, moulds and yeasts Multicellular (except for yeasts) Eukaryotic (the opposite of prokaryotic) Range in size from microscopic to the
size of giant mushrooms Either saprotrophic or parasitic No photosynthesis They are NOT PLANTS

05 / 04 Thursday
Learning objective:To be able to describe how fungi perform:a) Digestionb) Reproductionc) Respiration
Starter1) Describe “extracellular digestion”2) Define “anaerobic respiration”3) Write down the aerobic respiration
equation4) Write down the anaerobic
respiration equation
Extracellular Digestion
Fungal Reproduction – Sexual & Asexual
Fungal Infections
Athlete’s Foot
Cordyceps
Anaerobic respiration (Fermentation)
Homolactic fermentation – common in animals and bacteria
Glucose → Lactic acid + water + energy
Heterolatic fermentation – common in fungi
Glucose → Alcohol + CO2 + water + energy
What have we learnt today? How do fungi eat? How do fungi reproduce? How do fungi respire?
09 / 04 Tuesday
Learning objective:Describe fungal respiration and how it is used in fermentation of food such as beer
Starter1) What are the three different types
of fungi?2) Describe the digestion of fungi3) Describe the reproduction of fungi4) Describe the respiration of fungi
Can you remember?
Aerobic Respiration – with oxygenSugar + O2 → CO2 + H2O + Energy
Anaerobic Respiration – no oxygenSugar → Lactic acid + H2O + Energy
Anaerobic respiration (Fermentation)
Homolactic fermentation – common in animals and bacteria
Glucose → Lactic acid + water + energy
Heterolatic fermentation – common in fungi
Glucose → Alcohol + CO2 + water + energy
Alcohol & CO2 = ???
Yeasts – unicellular fungi
Practical – Making ginger beerRecipe for a small (400ml) screw top bottle:• 0.75 cup sugar• 0.5 tsp tartaric acid• 0.5 tsp ground ginger• 0.5 tsp lemon essence
1. Add warm water until the bottle is 75% full.2. Add in the above and shake to dissolve.3. Now add 0.5 tsp dried yeast and gently shake. 4. Screw on lid and incubate for a couple of days.
What have we learnt today? Describe the anaerobic respiration in
common bacteria Describe the anaerobic respiration in
common fungi Name three foods fungi are used to
make
