Which of the following is the best definition of osmosis?

• A. Movement of molecules from an area of their higher concentration to an area of their lower concentration
• B. Movement of water across a semi permeable membrane from an area of high water concentration to an area of lower water concentration
• C. Movement of, molecules from an area of their lower concentration to an area of their higher concentration
• D. Movement of water across a semi-permeable membrane from an area of low water concentration to an area of higher water concentration

Answer 1

The correct option is B Movement of water across a semi permeable membrane from an area of high water concentration to an area of lower water concentration

Osmosis can be best defined as the movement of water across a semipermeable membrane from an area of high water concentration to an area of lower water concentration.

So, the correct answer is 'Movement of water across a semi permeable membrane from an area of high water concentration to an area of lower water concentration'.
