Osmosis | MCQs

Explanation

Osmosis is the movement of water molecules through a semipermeable membrane from an area of higher water concentration to lower concentration.

It is a vital process in biological systems for maintaining cell balance.

Explanation

Active Transport:

Requires energy (ATP) to move molecules against the concentration gradient (low → high).

Example: Sodium-potassium pump in cells.

Explanation

• Osmosis is the movement of water molecules from an area of higher water potential (high concentration of water molecules) to an area of lower water potential (low concentration of water molecules) through a selectively permeable membrane.
• This process helps to equalize the concentration of water molecules on both sides of the membrane.

Explanation

• Osmosis is the process where a solvent, typically water.
• It moves through a porous membrane from an area of lower solute concentration to an area of higher solute concentration.

Explanation

• Water enters the root hair through the process of osmosis.
• It is the movement of water molecules from a region of high concentration to a region of low concentration through a selectively permeable membrane.
