Reproduction in Yeast Cell

Materials Required

  • A beaker 
  • Warm water 
  • Sugar 
  • Dehydrated yeast powder 
  • Glass-slide 
  • Dropper 
  • Glass cover (coverslip) 
  • Compound microscope
  • Glass Rod
  • Spatula

 

The Procedure

Real Lab Procedure

  • Take some warm water in a beaker.   
  • Dissolve a spoonful of sugar in it.   
  • Now add about 1g of dehydrated yeast powder into the solution.   
  • Stir the solution using a glass rod.  
  • Keep the beaker in a warm place for about an hour.   
  • With the help of a dropper, place a drop of the solution on a clean micro-slide.   
  • Place a cover slip on it taking care that air bubbles do not enter beneath the cover glass.   
  • Observe the slide under the microscope.   

Simulator Procedure

  • Drag and drop the spatula towards the watch glass containing yeast, take a spatula of yeast, and put it into the beaker containing water.
  • Drag and drop the spatula towards the watch glass containing sugar, take a spatula of sugar, and put it in the same beaker containing water. 
  • Drag and drop the glass rod towards the beaker and thoroughly mix the solution. 
  • Drag and drop the dropper towards the beaker and take a few drops of the mixed solution. 
  • Now, drag and drop the dropper towards the glass slide and pour the few drops of mixed solution into the glass slide. 
  • Drag and drop the coverslip on the top of the glass slide. 
  • Drag and drop the slider towards the microscope and click on the eyepiece. 
  • Click on the adjustment button to view the image clearly. 
  • For coarse adjustments, you can either click on the left and right arrow of the ‘Coarse adjustment’ knob, seen on the left control panel.   
  • For fine adjustments, you can click on the left and right arrows of the ‘Fine adjustment ' knob available on the left control panel.  
  • Click on the 'Inference' button to learn about the structural details of the microscopic image.  
  • Click on the 'Next' button to match the correct labelling.  
  • Click on the ‘Reset’ button to redo the experiment.  

 

Observations

A few minute-rounded unicellular yeast cells can be observed. A few yeast cells have a bulb–like projection on their body. Some yeast cells appear like chains of 3-4 cells.
