04 / 04 Thursday Learning objective: To be able to draw, label and describe the structure of a generalised fungus

Starter 1)Define these terms: - aerobic respiration - anaerobic respiration 2)Give three differences between aerobic and anaerobic respiration

Anaerobic Respiration – without oxygen Sugar → Lactic acid + H 2 O + 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)Digestion b)Reproduction c)Respiration

Starter 1)Describe “extracellular digestion” 2)Define “anaerobic respiration” 3)Write down the aerobic respiration equation 4)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 + CO 2 + 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

Starter 1)What are the three different types of fungi? 2)Describe the digestion of fungi 3)Describe the reproduction of fungi 4)Describe the respiration of fungi

Can you remember? Aerobic Respiration – with oxygen Sugar + O 2 → CO 2 + H 2 O + Energy Anaerobic Respiration – no oxygen Sugar → Lactic acid + H 2 O + Energy

Anaerobic respiration (Fermentation)  Homolactic fermentation – common in animals and bacteria Glucose → Lactic acid + water + energy  Heterolatic fermentation – common in fungi Glucose → Alcohol + CO 2 + water + energy

Alcohol & CO2 = ???

Yeasts – unicellular fungi

Practical – Making ginger beer Recipe 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
