Question

osmosis is a form of passive transport. which defines osmosis? (1 point)
the movement of water across a semipermeable membrane up a concentration gradient from low to high, using no energy
the movement of water across a semipermeable membrane down a concentration gradient from high to low, using no energy
the movement of water across a semipermeable membrane down a concentration gradient from high to low, using energy
the movement of water across a semipermeable membrane up a concentration gradient from low to high, using energy

Explanation:

Osmosis is a passive - transport process where water moves across a semi - permeable membrane from an area of high water concentration (low solute concentration) to an area of low water concentration (high solute concentration) without the use of energy.

Answer:

the movement of water across a semipermeable membrane down a concentration gradient from high to low, using no energy
