If a cell is hypotonic, the direction of water is ____
|
|
Inside the cell membrane
|
|
|
Outside the cell membrane
|
|
|
Within the cell membrane
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -In hypotonic solutions, there is a net movement of water from the solution into the body. A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis.
Detailed explanation-2: -Water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic.
Detailed explanation-3: -The hypertonic solution has a lower water concentration than the hypotonic solution, so a concentration gradient of water now exists across the membrane. Water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic.
