Final answer:
Osmosis is important to cells because it helps maintain water balance and prevents cell swelling or shrinking leading to potential damage or death.
Step-by-step explanation:
Osmosis is important to cells because it helps maintain the balance of water and solutes inside the cells. This process allows cells to take in water when they need it and release it when they have excess. If cells take in too much water, they can swell and potentially burst. On the other hand, if cells don't get enough water, they can shrink and become dehydrated, eventually leading to cell death.
