A slice of bread, water sprayer, filter paper, dropper, Petri dish, glass slide, cover slip, forceps, Compound microscope.
Real lab procedure
- Take the filter and keep it inside the petri dish.
- Take a piece of bread.
- Place it on a filter paper kept in a Petri dish.
- Sprinkle some water on it using water sprayer.
- Close the petri dish.
- Leave it undisturbed in a warm shaded place for 2 - 3 days.
- Observe the surface of the bread slice kept in petri dish.
- You may find some thread-like structures on it.
- With a forceps, pull out a few threads like structure from the bread slice.
- Place the threads like structure (sample) on a glass slide.
- Add three to four drops of water over the sample by using dropper.
- Place a cover slip over the glass slide.
- Observe under the low power of microscope.
- Drag the forceps towards the bread slice, then click on it to take a few threads of fungi.
- Drag and drop the forceps with the thread of fungi towards the glass slide to drop it on the glass slide.
- Drag and drop the dropper towards the beaker to take few drops of water and put few drops of water on to the glass slide.
- Drag and drop the cover slip on to the glass slide.
- Drag and drop the glass slide towards the stage of the microscope to place it under the lens.
- Click on the eye piece to view the microscopic view.
- Click on the next button to view for the labelling of fungi.
- Click on the highlighted parts on the image to view the name and its functions observe each parts of fungi.
- Bread mould is a kind of fungus and the thread-like structures on the surface of moist bread are the hyphae of a fungus.
- Some hyphae develop a spherical or club-shaped body at the tips called sporangium.
- The sporangiophore is a specialized fungal hypha as a stalk of sporangium.
- The sporangium produces several hundreds of minute rounded spores.
- These spores are asexual reproductive bodies which are released into the atmosphere.
- Under certain conditions, these spores germinate into new hypae.
