That happens to bacteria on hypotonic solutions, they end up blasting due to excess of water intake. In hypertonic solutions the opposite happens they have water loss due to the medium they are in.
But eukariotic cells like yeast have protein-pumps-ATP-dependent that allows them to pump our ions in hypotonic media and in hypertonic media they pump water in to avoid dessication.

Yup, the yeast cell wall is strong and can withstand a lot of abuse. They also have a vacuole and those ATP driven pumps to even some things out across hypo / hyper tonic gradients

Because they have thick cell wall that protects them from osmotic shock. This disables water from coming into the cell and anables the yest to live in a wide variety of environments.
