Question

Why the colonies of yeast do not multiply in water but multiply in sugar solution?

Answer 1

The yeast respire from the sugar solution and multiples because of the energy contained in it.

There is no such energy source in water so that's why yeast can't multiply.

I hope this helps.

Answer 2

heya...


it is so becoz...
Sugar provides energy for sustaining all life activities in yeasts. In water, it fails to reproduce because of inadequate energy in its cells.
