Unit 3 Retake Part 1 (24-25)

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution. In the case of saltwater, salt is the solute.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution. In the case of saltwater, water is the solvent.

Front

What is a solution?

Back

A solution is a homogeneous mixture formed when a solute is dissolved in a solvent.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing it to swell and potentially burst.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a process by which substances move across a cell membrane with the help of transport proteins, without the use of energy.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy.

Front

What direction does active transport move substances?

Back

Active transport moves substances from an area of low concentration to an area of high concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.
