General KnowledgeBiology
- Ahigher concentration to its lower concentration through a cell wall.
- Blower concentration to its higher concentration through a fully permeable membrane. through a fully permeable membrane.
- Chigher concentration to its lower concentration through a fully permeable membrane. through a fully permeable membrane.
- Dhigher concentration to its lower concentration through a semi-permeable membrane. through a semi-permeable membrane.
Explanation
Osmosis is the movement of water molecules from the region of higher water concentration to the region of lower water concentration through a semi-permeable (selectively permeable) membrane. Movement through a fully permeable membrane or a cell wall does not constitute osmosis, and water does not move from lower to higher concentration. The correct description is option D.
