Cell Transport

Front

Why are diffusion and osmosis important to cells?

Back

It allows them to take in and get rid of materials without using energy.

Front

Where is there a low concentration of dye?

Back

At the bottom of the cup.

Front

What does permeable mean?

Back

Things can pass through.

Front

What is it called when particles move from areas of high concentration to areas of low concentration?

Back

Front

What is the term for a solution with LESS WATER and MORE SOLUTES compared to the cell?

Back

Hypertonic.

Front

What is osmosis?

Back

The movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What does isotonic mean?

Back

A solution with equal concentrations of solutes inside and outside the cell.

Front

What is a concentration gradient?

Back

A difference in the concentration of a substance across a space.

Front

What is endocytosis?

Back

The process by which cells take in substances by engulfing them in a membrane.
