What is passive transport?
Which of the following processes does NOT require energy?
In which direction do molecules move during diffusion?
What is the main driving force behind diffusion?
Which type of molecules can diffuse freely across the cell membrane?
What is osmosis?
What kind of solution is saltwater (seawater) to a cell placed in it?
A cell placed in a hypotonic solution will:
Which term describes the concentration of solutes outside the cell being equal to the concentration inside the cell?
What happens to red blood cells in distilled water?
Which of the following is NOT a factor that affects the rate of diffusion?
Facilitated diffusion requires:
Which structure regulates what enters and exits a cell?
What is the effect of temperature on the rate of diffusion?
What type of solution causes cells to lose water when placed in it?
What role does the semi-permeable membrane play in osmosis?
Which of the following can affect osmosis?
What is the main function of osmosis in cells?
In which scenario will osmosis stop?
What is the primary factor that drives water movement in osmosis?
Active transport differs from passive transport in that it:
Cell membranes are selectively permeable. This means they:
What would happen to a red blood cell if it were placed in a solution of 0.9% salt?
Which process is responsible for the reabsorption of water in the kidney?
Osmosis is the movement of solutes across a membrane.
Diffusion can occur through a semipermeable membrane.
Active transport occurs against a concentration gradient.
Water molecules can freely cross the cell membrane.
Osmosis only involves the movement of solutes.
Facilitated diffusion requires energy to occur.
Hypertonic solutions cause cells to gain water when cells are placed within them.
Molecules move from an area of high concentration to an area of low concentration during diffusion.
All forms of passive transport are rapid processes.
What provides the structural support for a plant cell during osmosis?
If a cell is placed in a solution that is greater in solute concentration than its cytoplasm, the cell will:
Which of the following is a form of passive transport?
What happens to a cell in an isotonic solution?
The process of water moving into a cell is called:
In which type of environment do animal cells thrive best?
Which factor does NOT influence diffusion rates?
The bursting of cells due to excessive water intake is called:
Which of the following molecules typically requires facilitated diffusion?
A plant cell in a hypertonic solution will:
What occurs during dynamic equilibrium?
