Final answer:
A hypotonic solution has a lower solute concentration compared to the cell's internal environment, causing water to enter the cell and potentially leading to cell swelling.
Step-by-step explanation:
The solution that would have a solute concentration lower than the concentration found inside a cell is known as a hypotonic solution. In a hypotonic situation, the external solution has a lower concentration of solutes, which means it has a higher concentration of water when compared to the cell's internal environment. Consequently, water will move down its concentration gradient and enter into the cell, potentially causing the cell to swell and possibly lyse if excessive water is absorbed.
