Why excess sugar would slacken yeast growth?

Excess sugar produces a very negative water potential and this

causes water to move out of the yeast cells into the sugar solution

(by osmosis)- the cells become dehydrated, they do not have enough

water for cell growth (yeast cells are usually 90% water).
