Question

osmosis: _____ transport of ___ molecules through a _____

• solute: something that is ________ in water to make a ________
• solution: a liquid that has a _______ dissolved in it

kool - aid example:

• the solute is the _______________ because it mixes with the water
• the solution is the _____________ because it is the product of the ______ + water

tonicity

• tonicity: the _______________ of solute in a solution
• hypertonic: the concentration of _______ in the solution is _____________ than in the cell
• hypotonic: the concentration of _______ in the solution is _____________ than in the cell
• isotonic: the _____________ of solute in the _____ is _____________ as in the cell

Explanation:

• Osmosis is a passive process where water molecules move through a selectively permeable membrane.
• A solute is a substance that dissolves (is soluble) in a solvent (like water) to form a solution.
• In the Kool - Aid example, the Kool - Aid powder is the solute as it mixes with water (the solvent), and the resulting drink is the solution.
• Tonicity refers to the concentration of solute. In a hypertonic solution, the solute concentration is higher than in the cell; in a hypotonic solution, it is lower; and in an isotonic solution, the solute concentration in the solution is the same as in the cell.

Answer:

• Osmosis: passive transport of water molecules through a selectively permeable membrane
• solute: something that is soluble in water to make a solution
• solution: a liquid that has a solute dissolved in it
• Kool - Aid Example:
• the solute is the Kool - Aid powder because it mixes with the water
• the solution is the Kool - Aid drink because it is the product of the Kool - Aid powder + water
• TONICITY
• tonicity: the concentration of solute in a solution
• hypertonic: the concentration of solute in the solution is higher than in the cell
• hypotonic: the concentration of solute in the solution is lower than in the cell
• isotonic: the concentration of solute in the solution is the same as in the cell
