QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Cell Membrane and Transport.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
A cell is placed in a solution and water moves into the cell. Is the solution hypertonic, hypotonic, or isotonic to the cell?
A cell uses energy to move a substance from a low concentration to a high concentration. What type of transport is this?
Describe the direction of water movement when a cell is placed in an isotonic solution.
Describe what happens to an animal cell placed in a hypotonic solution.
Explain why facilitated diffusion is considered a type of passive transport.
Explain why plant cells do not burst when placed in a hypotonic solution, but animal cells might.
Name one example of a molecule that can pass through the cell membrane by simple diffusion.
What is the function of channel proteins in the cell membrane?
What is the function of glycoproteins in the cell membrane?
What is the main difference between passive and active transport?
What is the main difference between simple diffusion and facilitated diffusion?
What is the main function of the carbohydrate chains attached to proteins and lipids in the cell membrane?
What is the main reason why ions cannot easily cross the phospholipid bilayer?
What is the term for the movement of molecules from an area of high concentration to an area of low concentration?
What role do cholesterol molecules play in the cell membrane?
Which part of the phospholipid molecule is attracted to water?
