____ is a specific type of diffusion; it is the passage of water from a region of higher water concentration through a semi-permeable membrane to a region of ____ water concentration. Water moves in or out of a _____ until its concentration is the same on both sides of the cell membrane. A cell in a pure water solution (hypotonic solution) would be expected to _____ in volume due to the net flow of ____.

Osmosis is a specific type of diffusion; it is the passage of water from a region of higher water concentration through a semi-permeable membrane to a region of lower water concentration. Water moves in or out of a cell until its concentration is the same on both sides of the cell membrane. A cell in a pure water solution (hypotonic solution) would be expected to increase in volume due to the net flow of water.
