Passive Transport Review

Front

What type of solution causes blood cells to shrink?

Back

Hypertonic solution causes blood cells to shrink because it has a higher concentration of solutes compared to the inside of the cell, leading to water moving out of the cell.

Front

Which of the following is NOT a type of passive transport?

Back

Endocytosis is NOT a type of passive transport; it requires energy to move substances into the cell.

Front

Osmosis is the diffusion of ______________ molecules.

Back

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

Front

What does Passive Transport mean?

Back

Passive Transport means that no energy is used to move substances across a cell membrane.

Front

If there is 5 percent water inside a cell and 5 percent water outside a cell, what will happen?

Back

There will be no movement of water cells because the concentration of water is equal inside and outside the cell.

Front

Define Hypertonic solution.

Back

A hypertonic solution has a higher concentration of solutes compared to another solution, causing cells to lose water and shrink.

Front

Define Isotonic solution.

Back

An isotonic solution has the same concentration of solutes as another solution, resulting in no net movement of water.

Front

Define Hypotonic solution.

Back

A hypotonic solution has a lower concentration of solutes compared to another solution, causing cells to gain water and swell.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses protein channels to help move substances across the cell membrane.
