We have done an experiment to study how temperature affects cell division in unicellular living things.
Natural yeast is very easy to find in any supermarket and is a great way to obtain cells for experiments.Only one gram of this yeast contains billions of cells!
We dissolved some yeast in water and added some sugar. We placed a small amount of this mixture in the fridge and some in the bain Marie at 37ºC.
