What term describes the movement of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration?

Explanation

Osmosis is the movement of water molecules across a semi-permeable membrane from a region of lower solute concentration to a region of higher solute concentration, continuing until the concentration on both sides becomes more balanced. This process is essential for maintaining proper fluid balance within living cells, since cell membranes are semi-permeable and allow water to pass through more easily than many dissolved substances. Osmosis explains everyday phenomena such as why a wilted plant can become firm again after its roots absorb water. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
