The molecule that is transported across the cell membrane during osmosis is water.
During osmosis, the molecule that is primarily transported across the cell membrane is water.
The molecule that is primarily transported across the cell membrane during osmosis is water. Osmosis is a type of passive transport where water molecules move from an area of higher water concentration (lower solute concentration) to an area of lower water concentration (higher solute concentration) through a selectively permeable membrane, such as the cell membrane. This movement of water helps to maintain the balance of water and solute concentrations inside and outside the cell. Therefore, the correct answer is water.
