Which of the following is the best definition of osmosis?The movement of oxygen molecules across a partially permeable membrane from a region of higher oxygen concentration to a region of lower oxygen concentration.The net movement of dissolved substances from an area of higher concentration to an area of lower concentration.The net movement of water molecules across a partially permeable membrane from a region of higher water concentration to a region of lower water concentration.A process that moves substances across a membrane from an area of low concentration to an area of high concentration, using energy transferred during respiration.

Solution

The best definition of osmosis is: "The net movement of water molecules across a partially permeable membrane from a region of higher water concentration to a region of lower water concentration." This definition accurately describes osmosis as it specifically involves the movement of water molecules, not just any dissolved substances or oxygen molecules, across a membrane due to concentration differences. It also does not require energy, unlike the process described in the last option.
