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.
