Question

Water moves via osmosis across plasma cell membranes in which direction?

a) From high concentration to low concentration
b) From low concentration to high concentration
c) It doesn't move through osmosis
d) In both directions simultaneously

Answer 1

Water moves via osmosis from an area of high water concentration to an area of low water concentration across a semi-permeable membrane.

Step-by-step explanation:

Water moves via osmosis across plasma cell membranes from a region of high water concentration to a region of low water concentration. This process occurs along an osmotic gradient, where water moves from an area where solute concentration is low (thus, water concentration is high) to an area where solute concentration is high (and water concentration is low). This directional movement allows cells to maintain osmotic balance with their environment and is essential for various physiological processes in the body.
