‣
- Cant make own food
- Gather food from other organisms

- Athletes Foot
‣
‣
- Can get food from live or dead hosts
‣
- soft rot on food
‣
‣
- Live off dead organic matter
‣
- Mushrooms
- Bread Mould

‣
- Mushrooms that can be bought in the shop

- Studying the spore prints

‣
- Saprophytic
‣
- Bread mould
‣
‣
‣
- Allows the fungi to spread rapidly
‣
- Anchorage
- Absorption of nutrients
‣
- Allows the haploid spores to develop
‣
- Vertical hyphae that grows up out of the substrate
‣
- Swelling of the sporangiophore
‣
- It is an ark wall that separates the apophysis and the sporangium
‣
- The body of the rhizopus containing the hyphea and rhizoids in the substrate
‣
‣
BOTH !!!!
‣
‣
- Sporolation
‣
- Hyphae grows up from substrate to form sporangiophore
- Tips swell to form a sporangium
- Cells in sporangium divide by mitosis to produce haploid spores
- Sporangium then splits and the spores are blown away and can grow into a new Rhizopus if they land on a suitable substrate
‣
‣
- In adverse conditions where asexual reproduction is not possible
‣
- Dehydration
‣
- Two chemically different hyphae align (+) and a (-)
- Swellings form and they touch forming the Progametangia
- Haploid spores flow into swellings
- Cross Walls form preventing other haploid nuclei entering
- The gametangia is now formed
- The walls separating the gametangia break down and the haploid nuclei mix together to form a zygote nuclei
- This zygote nuclei is then surrounded by a tough walled zygospore
- This zygospore germinates by meiosis
- Hyphae grows out of the zygospore forming a sporangiophore
- The tips swell to form sporangium
- The spores are then released when sporangium splits

‣
- Anaerobically

- Fermentation
‣
- Breakdown carbohydrates
- Produce alcohol and CO2
‣
‣
- Asexually
‣
- Budding
‣
- Parent cell divides by mitosis
- One nucleus and some cytoplasm enters a small bud on the side of parent cell
- Bud may remain attached and continue to divide by mitosis forming more buds
‣
- Colony
OR
- Bud may separate and form a single cell
- All cells are identical

‣
- Yeasts are used to produce alcohols (brewing)
- Fungi such as mushrooms are grown as a source of food
‣
- Cause fungal diseases
‣
- Athletes foot
- Destroys food
‣
- Bread mould
- Potato blight
‣
- Measures are taken to exclude unwanted micro-organisms
‣
- Means all micro-organisms are destroyed
