The correct definition of osmosis is:
The movement of water across a semipermeable membrane down a concentration gradient from high to low, using no energy.
The correct definition of osmosis is: "the movement of water across a semipermeable membrane down a concentration gradient from high to low, using no energy."
To arrive at this answer, we can break down the options and identify the key components of osmosis:
1. "the movement of water": This defines the substance that is moving across the membrane.
2. "across a semipermeable membrane": This specifies the type of membrane through which the water moves.
3. "down a concentration gradient": This describes the direction of movement of the water from an area of higher concentration to an area of lower concentration.
4. "from high to low": This further emphasizes the direction of movement.
5. "using no energy": This states that osmosis is a form of passive transport that does not require the input of energy.
By considering these components, we can determine that the correct definition of osmosis is: "the movement of water across a semipermeable membrane down a concentration gradient from high to low, using no energy."
