Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Fill in the blank:Osmosis is the movement of ____ across a cell membrane from high to low.
A
Carbon dioxide
B
Starch
C
Water
D
Oxygen
Explanation: 

Detailed explanation-1: -Osmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.

Detailed explanation-2: -Water moves across cell membranes by diffusion, in a process known as osmosis. Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.

Detailed explanation-3: -Osmosis happens when molecules move from higher to lower concentrations, but diffusion happens when it is reversed.

Detailed explanation-4: -In osmosis, water moves from areas of low concentration of solute to areas of high concentration of solute.
