Cell Transport

Front

What is osmosis?

Back

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

Front

What substance moves during osmosis?

Back

Water.

Front

In which direction does water move through a semipermeable membrane when one side has a higher solute concentration?

Back

Water moves from the side with lower solute concentration to the side with higher solute concentration.

Front

What type of solution causes water to leave a cell?

Back

Hypertonic solution.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What is an isotonic solution?

Back

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

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell.

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 is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically down their concentration gradient.

Front

What type of transport describes the movement of oxygen into red blood cells?

Back

Simple diffusion.
